iMIS supports three gateway options for credit card authorization:
1. Payflow Pro (see Implementing Payflow Pro as an authorization gateway), offered by PayPal, (previously Verisign), based in the United States
2. TNSPay (formerly SafePay) (see Implementing TNSPay as an authorization gateway), offered by TNS, based in Australia and focused on international sales
3. Custom gateways (see Creating a custom credit card gateway), which you can create using ASI-supplied code and documentation
All three gateway options work with the PCI Compliance options (see Implementing Advanced PCI Compliance options) available in AR/Cash Setup.
Note: If Advanced PCI Compliance|topic=Implementing Advanced PCI Compliance options > Do not retain cardholder information is enabled, iMIS saves transactions without cardholder data and shows only gateway reference number and authorization code fields.
