On-Device SAF
On this page:
All Simplify versions support POS SAF (Store and Forward) If enabled, Simplify will send to the POS all data required for the POS to perform SAF processing. This requires the POS to store sensitive data.
Starting with build 115, Simplify supports On-Device SAF (Store and Forward) on Tetra devices (Simplify versions 2.03.xxx). If this feature is enabled, Simplify performs SAF processing and does not send any sensitive data to the POS.
Note:
On-Device SAF is recommended with OnGuard as the encryption mode, as Voltage is not valid for PCI-validated P2PE.
On-Device SAF and POS SAF are not compatible. If Simplify is configured to support either method of SAF processing, the other method is not allowed.
