I just purchased and/or upgraded my POS software and it is a First Data Secure Transport Network (formerly Datawire)-enabled version. It calls for a Datawire ID (DID). What is a DID and where can I get one?


Before being transported via the First Data Secure Transport Network, every transaction is authenticated using a Datawire ID (DID), which is a unique customer identifier generated by the Secure Transport provisioning system and assigned to each client who will use the Secure Transport Network. In order to be authenticated as a valid user of the Secure Transport Network I, the DID must be sent with each transaction request. Typically, the DID is arranged through the merchant services provider at time of activation, when Merchant IDs (MIDs) and/or Terminal IDs (TIDs) are provided.
