Get more secure payment processing with point-to-point encryption (P2PE) provided through devices from industry leading hardware manufacturers. Express maximizes card data protection and transaction security from the point of swipe all the way to authorization. All of our EMV capable devices support P2PE as well. This document provides information on using an encrypted device via a direct integration with the Express processing platform.

 

Developers Need To Know

  1. The device must be encrypted with an Express encryption key, and depending on your integration method, may or may not support keyboard-emulation.
  2. Encrypted Swiped/Keyed Data and Card Data Key Serial Number alpha characters should be capitalized when submitted to the Express platform.
