SIM uses scripting techniques to authenticate transactions with a unique transaction fingerprint.

The Authorize.Net Payment Gateway can handle all the steps in the secure transaction process – payment data collection, data submission and the response to the customer – while keeping Authorize.Net virtually transparent.

  • Payment gateway hosted payment form employs 128-bit SSL data encryption.
  • Digital fingerprints enhance security, providing multiple layers of authentication.
  • Customize the look and feel of the payment gateway hosted payment form and/or receipt page.
