Review Injected PIN Encryption Keys or Point to Point Encryption Keys on Ingenico Telium Devices

Timothy Hughes
  • Updated

Description: Utilize the steps below to determine if an encryption key is present. 

Note: The steps below only confirm an encryption key is present, not that it is valid. Only the Key Injection Facility (KIF) can validate a PIN Encryption Key. Shift4 agents can only validate if a Shift4 Point to Point Encryption (P2PE) Key is valid.

Note: If utilizing the hardware device for Signature Capture ONLY, no Keys may be present on the device.

To verify whether encryption is in place on the device, perform the following:

  1. Reboot the PIN Pad.
Model Type Reset Procedure
iSC250/480:

 

Press and Hold the Clear (Yellow) and the Minus ( - ) Keys until the device chirps.

 

iPP320/350:

iWL252/258:

iCMP/iSMPv4:

 

Press and Hold the Clear (Yellow) and the Period ( . ) Keys until the device chirps.

 
  1. Wait for the PIN Pad to display the Retail Base (RBA) version information screen.

  2. When the Ingenico Copyright screen appears, press 2, 6, 3, 4, and Enter. Shortly after this, the device will ask you to either press (+) Plus or (F) Function for menu. *If the device requests (F) Function for menu, but there is no (F) key simply press (+) Plus instead.

    If successful, the Functions menu should display. If it does not, please reboot again try performing the code entry again.

    1. You may use the relevant keys to scroll up and down to view every index. Any value other than No Key indicates a key is in place.

    1. The PIN Encryption Key will generally be located in Slot 0 or Slot 1, more commonly the former. The P2PE Key will be located in Slot 4 in almost every case. Only one Key may be present if the merchant is not utilizing PIN entry or P2PE.
