What is the Vault used for?
The Vault helps reduce the PCI burden by providing a non-resident encrypted storage solution. The vault employs a Globally Unique Identifier (GUID) also known as an alias or token, which is stored on the merchant’s server or host software to represent the encrypted data securely stored behind our firewall. Transactions are processed using the GUID, their Paya Merchant_ID, and Paya M_Key.
