Verifone Validation Logic

To provide an example of the Verifone validation logic, let us assume that you set up the following two blocking rulesets for a given merchant entity:

1. Blocking Ruleset A
   
   • Rule 1: Issuer Country equals to Country A
   • Rule 2: Amount is greater than 100
   • Rule 3: Currency Code equals to Currency Code B
2. Blocking Ruleset B
   
   • Rule 1: Customer Country Code is not equal to Country Code C

After saving the blocking rulesets, transaction #001 is initiated with the merchant entity with the following properties:

• 99 Currency Code B with Issuer Country A from Shopper Country D

And the following logic is applied by the Verifone Validation Service for Transaction #001:

• Blocking Ruleset A, Rule 1 is triggered
• Blocking Ruleset A, Rule 2 is not triggered
• Blocking Ruleset A, Rule 3 is triggered
• Blocking Ruleset A is not activated
• Blocking Ruleset B, Rule 1 is triggered
• Blocking Ruleset B is activated
• Result: The Transaction is blocked by the Verifone Validation Service

Transaction #002 is initiated with the merchant entity with the following properties:

• 101 Currency Code A with Issuer Country B from Shopper Country C

The following logic is applied by the Verifone Validation Service for transaction #002:

• Blocking Ruleset A, Rule 1 is not triggered
• Blocking Ruleset A, Rule 2 is triggered
• Blocking Ruleset A, Rule 3 is not triggered
• Blocking Ruleset A is not activated
• Blocking Ruleset B, Rule 1 is not triggered
• Blocking Ruleset B is not activated
• Result: The transaction is not blocked by the Verifone Validation Service, and is sent for further processing
