POS Vendors

A third-party servicer (TPS) is a company that provides point-of-sale processing services to medium-size and smaller merchants. Becoming a SIGIS member and implementing the IIAS standard into a TPS’s point of sale system allows a simpler streamlined certification process for merchants that are using a SIGIS certified POS system.

Membership in SIGIS offers TPS access to the following programs:.

SIGIS IIAS Transaction and Data Retention Specification

The SIGIS Specification outlines the requirements needed for merchants, acquirers, processors, card issuers and plan administrators to support an IIAS.

TPS IIAS Certification

The key requirement for a company to qualify as a TPS whose merchants may take advantage of the streamlined certification is that the TPS provides and operates all of the following services/systems on behalf of its merchant clients:

  • Inventory management
  • Cash register/POS transaction processing
  • Payment card processing

The TPS must have an established relationship with an acquiring processor for purposes of certifying the POS and payment card processing. If the TPS's software allows the merchant to make changes that will affect IIAS processing after the software is installed, its merchant clients who use that software will not be able to use the streamlined certification. In those cases, the merchant may certify using the standard SIGIS IIAS Merchant Self-Assessment form.

Once the POS Vendor is IIAS certified with SIGIS, merchants that use a certified-TPS solution version and acquirer, and are a SIGIS Member, can certify with SIGIS by completing a simplified, TPS Merchant certification form.

To become IIAS certified, a TPS completes a similar IIAS certification process as merchants. This requires completion of a TPS Self-Assessment Certification Form, a technical testing certification by the TPS’s acquirer, use of the SIGIS Eligible Product List, and arrangements to support transaction data retention/retrieval. A TPS will not be permitted to claim that it supports IIAS transactions using the SIGIS standard until it has been certified to the IIAS standards developed and approved by SIGIS.

SIGIS provides additional support through our Help Desk that is available to answer any questions regarding the programs listed above.
