June 2026

Android Terminal App

Version 5.39.0

🐞 Bug Fixes - Card language selection: Fixed issue where the cardholder language was not correctly selected for CB and Conecs cards on Sunmi and Elo terminals. The terminal now uses the language preference stored on the card when available, helping cardholders complete the payment in their preferred language. - IRIS reversals: Resolved issue where an approved IRIS payment could be automatically reversed while the merchant receipt was still printed. IRIS payments now complete with the correct final status, reducing confusion for merchants and customers. - InterApp preauthorisation: Fixed issue where a Card Present preauthorisation could be initiated with a zero amount after a cancelled IRIS payment. The requested amount is now preserved correctly when a new InterApp preauthorisation is started after an IRIS cancellation. - Greek UI on Android 16: Resolved layout issues on Android 16 when the terminal language was set to Greek. Headers, dates and transaction tiles are now displayed correctly on affected screens. - Bill Payments: Resolved issue where Bill Payments initiated through App2App could fail after an AADE transaction. Bill Payments can now be processed successfully without AADE parameters when they are not required for that payment type. - Double charges: Fixed issue where tapping the Continue button multiple times on DCC, installment or loyalty screens could create duplicate payment requests. The terminal now prevents repeated taps on critical action buttons, reducing the risk of duplicate charges. - Account type selection: Improved handling of cards that require the cardholder to choose between multiple account types. The transaction now continues or times out consistently, even when the customer selects an option at the same time as the timeout expires. - Terminal freezing: Resolved issue where Android terminals could freeze after application selection when using specific dual-branded cards. The payment flow is now more stable for merchants processing transactions with cards that include multiple payment applications or account types. - AADE ECR status: Fixed issue where terminals with AADE enabled could return an incorrect ECR status after a connectivity problem. The cash register now receives the correct terminal status, improving transaction handling for integrated merchants. - Oracle integrations: Fixed transaction declines affecting Oracle OPI and Symphony F&B integrations. Card-present payments initiated through these integrations are now processed with the correct transaction type. - DCC refund amount: Fixed issue where DCC refunds initiated with only the orderCode could refund the original transaction amount instead of the converted payment amount. Refunds now use the correct amount for the currency selected during the original DCC transaction. - DCC refund response: Resolved issue where DCC refunds could fail because the requested refund amount was slightly higher than the original transaction amount. Refund amounts are now capped correctly, helping merchants complete DCC refunds from the terminal transaction history. - DCC refund session: Fixed mismatch between amount and currency code in DCC refund session responses. The refund session status now returns consistent amount and currency information for easier reconciliation. - MB Way payments: Fixed issue where a card tap during the MB Way QR flow could potentially trigger more than one payment method for the same sale. The payment flow now prevents multiple charging when MB Way is displayed and a card is presented at the same time. - Sunmi Play Store message: Fixed issue where Sunmi P-series terminals displayed Google Play Store warnings on app launch. Terminals without Google Play Services no longer show unnecessary warning messages to merchants. - Cloud payment response: Fixed issue where successful cloud payments on Sunmi terminals could incorrectly return a cancellation response. Merchants now receive the correct payment result, reducing the risk of retrying an already approved transaction. - Sunmi installation: Fixed installation issue on Sunmi terminals when another Viva app flavour was already installed. The installation flow is now more reliable across demo, UAT and production environments. - Unattended network retry: Fixed issue where unattended terminals could send multiple login retry requests after a network error. The terminal now performs a single scheduled retry, improving stability in unattended environments. ✅ Improvements - InterApp refactoring: Updated InterApp sale, refund, unreferenced refund and preauthorisation capture flows to use the latest transaction handling implementation. This provides a more consistent integration flow for partners using InterApp payment actions. - SAF cancellation: Improved Store and Forward cancellation handling when a terminal returns online. The terminal now continues attempting the appropriate reversal when needed, reducing the risk of duplicate charges after offline processing. - PAX IM30 v2: Added support for PAX IM30 v2 terminals. The terminal app now recognises the new hardware revision and supports the updated activation and card presentment flow. - KT-2 presentment icon: Updated the card presentment indicator for KT-2 terminals. The contactless tap icon is now aligned with the terminal NFC reader position, making the payment experience clearer for cardholders. - Refresh token mechanism: Replaced the legacy refresh token mechanism with an updated implementation. Authentication refresh is now handled more consistently, reducing the risk of unexpected logout scenarios. - Slovenian receipts: Updated terminal receipt translations for Slovenia. Receipt wording is now aligned with the requirements for the recent country launch.

Viva Fiscal improvements

✅ Improvements - Viva Fiscal tipping: Added support for tips during fiscalised transactions. Merchants using Viva Fiscal can now accept tips while keeping the transaction fiscalised. - Fiscal capture: Added Capture and ISV Capture support across Viva Fiscal Terminal API protocols. Capture operations are now available through App-to-App, Cloud and P2P integrations. - Fiscal refunds: Added support for non-cash refunds in Viva Fiscal. Merchants and ISVs can now process fiscalised refunds for supported Alternative Payment Methods, not only card payments. - Fiscal amount pad: Added automatic amount pad locking for Greek Viva Fiscal merchants. Once fiscalisation is active, the payment amount must come from the fiscal system and can no longer be manually changed on the terminal. - Fiscal signature: Added the sourceTerminalId field to the fiscal signature. This improves transaction traceability by identifying the terminal that initiated the fiscalised payment.

Version 5.39.1

🐞 Bug Fixes - Tip dialog: Fixed crash in the tip dialog caused by translation strings. The tip screen now opens correctly in affected languages, and tip-related wording has been corrected where needed.

iOS

Version 5.38.1

🐞 Bug Fixes - Force logout: Fixed crash that could occur when restarting activation after a failed authentication refresh. The app now completes the logout and cleanup process correctly when the user restarts activation. - Fiscalisation APM transactions: Fixed issue causing fiscalisation failures for Alternative Payment Method transactions. APM transactions can now be fiscalised successfully after payment completion.

PAX

Version 4.37.0

August 2026

Android Terminal App

Version 5.40.0

Released: August 3, 2026

✅ Improvements

• Cartes Bancaires refunds: Added support for referenced refunds without requiring the physical presentation of the Cartes Bancaires card used for the original sale.
• Capture transaction references: Capture requests now use the MerchantTrns or clientTransactionId value supplied by the integrator, instead of automatically inheriting the value from the parent transaction. This applies to Cloud, P2P, and InterApp integrations. When neither parameter is supplied, the value from the parent transaction continues to be used.
• Android 14 support: Viva SoftPOS is now fully compatible with Android 14, including support for the Ciontek SmartS device.
• PIN protection policy: Strengthened application PIN validation to help protect against unauthorized access and fraudulent refunds. New or updated PINs must contain at least four digits and cannot use repeated or sequential patterns, such as 1111, 1234, or 4321. The policy applies whenever a PIN is created or changed through application settings, the activation wizard, P2P mode, or App-to-App commands such as activatePos and setMode. Existing PINs remain valid until they are changed.
• PAX A77 certification: Completed Viva SoftPOS certification for PAX A77 devices running Android 10 or later.
• App-to-App reset safeguards: Enhanced soft and full reset requests to process stored offline transactions and pending reversals before resetting the application. The reset is stopped if the SAF journal cannot be uploaded or cleared, or if a pending reversal cannot be completed. The caller receives a distinct error response for each failure scenario, while an on-screen progress indicator remains visible until the outcome is confirmed.
• Cloud launch-interapp action: Added a new launch-interapp action for Cloud integrations, enabling Viva SoftPOS to open a third-party application. The action is available with both merchant and ISV credentials.
• Transaction type label: Added a label to the card-presentment screen so merchants can clearly identify the transaction type, including Sale, Preauthorization, Refund, Rebate, Fast Refund, and Unreferenced Refund.
• Surcharge amounts in Batch Summary: Added a dedicated surcharge section to the Batch Report. The Sales section now excludes surcharge amounts, providing a clear distinction between sales revenue and collected surcharges.

🐞 Bug Fixes

• Offline limits display: Fixed inconsistent values on the Offline Limits screen, where the offline transaction count could appear as zero while the total amount remained non-zero, or vice versa.
• Bancontact logo: Fixed an issue that prevented the Bancontact logo from appearing in the transaction list.
• Batch Details stability: Fixed a rare issue that could cause the Batch Details screen to crash when a network error occurred while the transaction list was loading.
• Cartes Bancaires contactless CVM: Fixed an issue where Cartes Bancaires cardholders could be incorrectly prompted to enter a PIN for contactless transactions below the EUR 50 CVM threshold.
• Preauthorization capture source: Fixed an issue where the reseller source code supplied in a preauthorization capture request was ignored. Captured transactions are now linked to the specified source code instead of the default source.
• InterApp installment parameters: Fixed an issue that caused InterApp sale requests to fail when preferredInstallments was empty and withInstallments was set to false.
• App-to-App abort action: Fixed an issue that prevented the App-to-App abort action from being recognized. When an active transaction exists, the action now cancels it correctly. When no active transaction exists, the application returns error code -55 (Nothing_to_abort).
• Tipping selection: Fixed an issue on the Tipping screen by keeping the Continue button disabled until the user selects a tipping option or chooses No, thanks.
• IRIS cancellation flow: Fixed an issue that prevented users from selecting another payment method after cancelling an IRIS payment.
• Preloaded transaction totals: Fixed an issue affecting preloaded Cloud transactions with tips in the merchant flow. The returned grand total now includes tipAmount, as expected.
• IRIS clientTransactionId: Fixed an issue where clientTransactionId was not stored for IRIS payments.
• MOTO transaction stability: Fixed an issue that could force the application to restart after a MOTO transaction.
• Cartes Bancaires offline transactions: Added AID A0000000426010 to the supported AID list, resolving an issue affecting Cartes Bancaires offline transactions.

September 2026

Android Terminal App

Version 5.41.0

🐞 Bug Fixes

• Duplicate charges: Resolved an issue where an incorrect transaction response could lead to a second payment attempt for specific payment methods, including Multibanco and MB Way.
• Unreferenced refunds: Fixed issues that could result in duplicate refunds or unnecessary PIN prompts during refund and cancellation flows.
• Offline payments: Improved offline transaction stability, including fixes for terminal freezing and transaction failures when connectivity is unavailable.
• Preauthorisation sessions: Fixed an issue where a successfully completed preauthorisation capture could return “Session not found” when the session details were requested. Captured sessions can now be retrieved correctly through Cloud REST API integrations.
• DCC refunds: Fixed issues affecting DCC refund responses for InterApp integrations and improved currency-conversion information displayed during refunds.
• Transaction information: Fixed missing merchant and customer transaction information and improved stability when accessing transactions from transaction history.
• SUNMI P2 SmartPad display: Fixed incorrect display of large transaction amounts on SUNMI P2 SmartPad devices.

✅ Improvements

October 2026

Android Terminal App

Version 5.42.0

✅ Improvements

• POS activation – kiosk lock: Added the lockKiosk parameter to POS Activation. It pins Viva SoftPOS to the terminal screen in kiosk mode, so the callback is returned to the third-party app only if activation fails.
• Tip settings deeplink: Added the set_tip_settings action to configure tipping through a deeplink. Parameters: enableTip (default true), and enableCustomTip, enablePercentageTip and enableRoundTip (default false). enableTip=false overrides all other parameters, and enableRoundTip=true turns off the custom and percentage tip options.
• Advanced settings deeplink: Added the set_advanced_settings action with the parameters enableTerminalService (default false), keepAliveService and updateUserStatus (default true). If enableTerminalService is false, the other two parameters are ignored.
• Preselected tip: Added a “Preselected Tip xx%” setting so merchants can set a default tip percentage, which is highlighted as the middle option on the tipping screen.
• Skip SAF for Cloud REST API: Transactions initiated through the Cloud REST API now bypass Store and Forward (SAF), even when SAF is enabled in the merchant’s configuration.
• Feitian F360 support: Added full compatibility with the Feitian F360 unattended payment device. DCC and surcharge are not supported on this device because of its small screen. Kiosk mode, installments and loyalty are not supported yet.
• Sunmi P3KH support: Added full compatibility with the Sunmi P3KH (PCI) device.

🐞 Bug Fixes

• Card scheme selection timeout: Fixed an issue where the card presentment screen timed out unexpectedly after the card scheme was selected manually.
• Reprinting settings deeplink: Fixed an issue where the app became unresponsive when processing a ReprintingSettings deeplink request after an App-to-App sale in unattended mode.
• Hardware cancel button: Fixed an issue where pressing the red Cancel button on the terminal during PIN entry sent the user back to the card presentment screen.

Version 5.42.3

🐞 Bug Fixes

• Pin encoding issue on Sunmi P2 Smart Pad: Fixed a bug affecting the SUNMI P2 Smart Pad device where the PIN was encoded twice when the user entered it. The issue has been resolved to ensure the PIN is encoded only once during entry.

iOS Terminal App

Version 5.40.0

✅ Improvements

• Capture/refund handling: The app now rejects incoming sales requests with error code 1000 while a pre-authorization capture or card refund is in progress, preventing overlapping transactions.
• Abort after card is read: The app now accepts abort requests from integrated third-party apps or cashier systems even after the card has been read and the transaction has reached the PIN entry screen.
• ePOS activation parameters: Added skipExternalDeviceSetup and lockCapture (Boolean) and datecsTerminalCode (string, used only when pairing an external device) to the ePOS activation request.
• Request type labels: The card presentment screen now shows a label for each request type: “Hold Here to Pay” for sales (with “Temporary deposit” added for pre-authorizations) and “Hold Here for Refund”, with “Refund from” above the merchant name, for unreferenced refunds.
• Cloud launch-interapp action: Added the launch-interapp action for Cloud REST API integrations, enabling Viva SoftPOS to open a third-party application installed on the same device.
• Digital wallet indicator: Added an indicator in the Transactions list showing which digital wallet was used for a payment.

🐞 Bug Fixes

• Cloud REST API sales: Fixed an issue introduced in version 5.38.1 where sales requests sent through the Cloud REST API were not delivered to the terminal.
• Locked terminals: Fixed an issue that allowed payments on terminals with a locked status. Payments are now blocked, and users who open the app on a locked terminal are logged out automatically.
• MOTO abort: Fixed an issue where aborting a MOTO sale during card detail entry returned a failure status through InterApp instead of confirming the cancellation.

Version 5.40.1

🐞 Bug Fixes

• ISV batch details: Fixed an issue where transactions processed with ISV credentials were missing from batch details (“No transactions found”), although they appeared in All Transactions.
• Printing crash: Fixed a crash when the print dialog was displayed on the transaction result screen while an external printer was connected.

Paydroid Terminal App

Version 5.38.0

✅ Improvements

• Transaction type label: Added a label at the top of the card presentment screen showing the transaction type (Charge, Refund, Fast Refund or Pre-authorization). Refund amounts are also no longer shown as negative values (for example –€4.06), to avoid confusion about whether the amount is credited or deducted.
• Accessibility compliance: Added Phase 2 updates to support EU Accessibility Act (Directive (EU) ²⁰¹⁹⁄₈₈₂) compliance.
• Connection error code: The app now returns a dedicated CONNECTION_ERROR code to integrated third-party apps when it fails to launch because of lost internet connectivity.

• AADE keyboard (Greece only): Fixed an issue where the on-screen keyboard remained accessible when an AADE transaction was started.

CORE Updates

✅ Improvements

• Daily refund limit: Added a configurable daily refund limit per terminal to strengthen fraud prevention. The limit can only be requested or changed by the merchant, not by third-party partners. The counter is based on the terminal processing the refund, and excludes cancellations (same-day refunds), unreferenced refunds, rebates, Fast Refunds and e-commerce refunds.
• Wallet APIs: Three new API calls are available for wallet management: create a wallet account (POST /merchants/v1/wallets), send funds to a wallet account (POST /merchants/v1/wallets/{sourceWalletId}:send) and get wallet details (GET /merchants/v1/wallets). All calls require OAuth 2.0 authentication with Account Transactions credentials (Viva e-banking → Settings → API Access).
• Bank transfers default priority: The default priority for bank transfers is now Standard instead of Instant, reducing rejections when the recipient’s bank does not support instant transfers.
• ISV registration: ISV partners can now register with a mobile number whose country code differs from the registration country (for example, a partner in Estonia using a UK number).
• Magento plugin credentials: A new pair of credentials is now available in Viva e-banking (Settings → API Access) for use with the Magento plugin.

FRONT Updates

✅ Improvements

• Fiscalisation role for child users: Admins can now assign the new “Allow fiscalization” role to any child user. The role is available only when fiscalisation is enabled at merchant level.

🐞 Bug Fixes

• Smart Checkout cancel button: Fixed an issue where the Cancel button was invisible or hard to see when the configured color was white or very light.
