If you or one of your merchants is using the Authorize.Net Anywhere Commerce Walker C2X and/or the BBPOS Chipper™ 2X, via the Authorize.Net In-Person SDKs, you must update the EMV card reader to remove the expired 1152-bit key.


The 1152-bit key recently expired and it must be removed from the EMV card reader within six months. If no update occurs, and a chip card reader with an expired key requests authorization, the transaction will be declined. The 1152-bit key must be removed from EMV card readers no later than July 1, 2018.


Recommended Action

  • Update your In-Person SDK iOS, Android and Windows integration with the Firmware/Configuration Over-the-Air (OTA) remote update feature.


  • Utilize the In-Person SDKs sample applications in Net’s GitHub repositories.
