The P2PE VAS production architecture communicates directly with the Web Service for all card data decryption and optional card scoring.
The P2PE VAS Sandbox architecture communicates with a Web Service "test host" that stores magnetic fingerprint values for test cards issued. These test cards are used to simulate production card data decryption and optional card scoring during testing/certification. In addition, Velocity provides a Sandbox environment for integration, testing, and certification purposes.
P2PE VAS Implementation
Integration to the P2PE VAS requires a P2PE VAS-enabled workflowId that must be passed with each Commerce Web Services (CWS) transaction request. This workflowId is returned to the application in the response to the GetServiceInformation call during the Preparing the Application to Transact process of a CWS integration.
Optionally, a ScoreThreshold value can be passed with each transaction request to trigger card authentication.
Setting the ScoreThreshold Value
One of the key features of the security architecture is card authentication, which is used to identify counterfeit credit cards, debit cards, gift cards, and other cards at the point of swipe.
This makes it possible for card issuers to uniquely identify each physical card they produce by analyzing its magnetic "fingerprint". By storing this fingerprint, merchants are able to perform a fingerprint reference check to determine if the card is counterfeit, and should therefore be declined.
Card authentication, or card scoring, is performed based on the presence of the CWS BankcardTransactionData.ScoreThreshold parameter in each transaction authorization request.
•ScoreThreshold Present - Encrypted card data is decrypted and card scoring is performed based on the ScoreThreshold value passed in the transaction request.
•ScoreThreshold Null - Encrypted card data is decrypted, but no card scoring is performed.
P2PE VAS Requirements
Point-to-Point Encryption (P2PE) Value-Added Service (VAS) provides a comprehensive security solution that protects card data throughout the entire Commerce Web Services (CWS) transaction lifecycle. The VAS integrates directly to the Service to decrypt card data that was encrypted during initial swipe at the point-of-sale using a Secure Card Reader Authenticator (SCRA) device.
