eWIC Requirements for WIC Vendors
The USDA/FNS provides two publications that govern WIC EBT processing standards for all entities involved. These are the Operating Rules for WIC EBT and the Technical Implementation Guide (TIG). The Operating Rules address the operation of WIC EBT for all entities, including: retail system vendors, WIC Vendors, Acquirers and Processors. The TIG consists of the implementation guidelines of the X9.93 standards and specifications for processing WIC EBT transactions. If you are a Louisiana WIC Vendor, these documents contain the information you will need to provide to your cash register system/point-of-sale support to integrate WIC EBT into your existing system.
