OTP Required for TPN Change at POS.

Previously, terminals did not require additional authentication to change the TPN downloaded on the POS device. To strengthen security, a one-time passcode (OTP) is now required to change the Terminal Profile Number (TPN) on a POS terminal. The OTP can be obtained from the "Edit Parameters" Module on the iPOSpays Portal.

Example:

If the user wishes to replace the TPN on their POS terminal, they must:

  • Remove the old TPN and enter the new one

  • iPOSpays portal -> Edit Parameters -> Search and select the TPN from the search box at the top

  • Copy the OTP
