Known Issues

  • The Metadata documentation page does not show fields as being required. Please refer to the Swagger Documentation for this information.
  • The triPOS service may fail when a request is sent during a specific phase of initialization of a Vx805 PIN pad. To avoid this failure, do not make a request to a Vx805 PIN pad until the PIN pad is fully configured.
  • The RBA software running on the iSC250 has the following limitations on the GET /api/v1/selection{laneId} endpoint: 
       1. Some numeric-only strings (e.g. "123") are reserved as Prompt IDs in RBA and will not be displayed as raw text on the prompt or buttons. If this occurs, please try to put a space at the beginning of the string for it to be displayed correctly. 
       2. RBA currently displays "Input Accepted" on the PIN pad after the cardholder makes a selection. The PIN pad will remain on the "Input Accepted" screen, rather than the semi-custom screen, until a new request is sent to the PIN pad.
  • There is a connectivity issue with Ingenico Bluetooth devices (iCMP, iSMP4) when attempting to download files via Bluetooth connection. Please see Bluetooth Connectivity for workaround steps to download files to these devices.
  • Setting a custom idle screen image for the Verifone Mx915 and Mx925 with triPOS running on Linux fails because the mono installation is missing a dependency.
  • Verifone Mx9xx and Vx devices display a "CARD READ ERR" when a card containing only track 3 data is swiped. Transactions not canceled will time-out and return a PinPadException and "VerifoneXPI S20 timeout response" message. This issue is pending resolution from Verifone.
  • MasterCard contactless MSD for NFC Card and ApplePay issues on Mx devices
