Braintree Card Validation Rules
We recommend that you set a few rules governing validation of credit cards through the Braintree control panel. These rules will ensure that the security code (CVV) and zip code (Address Verification or AVS) are entered correctly when adding a credit card, which help with security, and also may lower your processing fee.
