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.
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.
Merchants with an Authorize.Net gateway account can use the card reader update feature in the Authorize.Net MPOS or VPOS applications to remove the expired keys.
