How can a TPS update an approved Certification that has approved merchants?
TPS’s that wish to update a certification that has approved merchants should contact SIGIS at email@example.com. The TPS will be asked to complete the “TPS Change Questionnaire” document. Upon review, the TPS will instructed on required steps. In some cases a simplified process may be available so as to not impact the approved merchants. Each situation will be evaluated based on the info provided in the TPS Change Questionnaire document.
To become IIAS certified, a POS vendor 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's acquirer will review the TPS Self-Assessment Certification Form and submit it to SIGIS for approval. 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.
