Luhn algorithm. The Luhn algorithm or Luhn formula, also known as the " modulus 10" or "mod 10" algorithm, named after its creator, IBM scientist Hans Peter Luhn, is a simple check digit formula used to validate a variety of identification numbers. It is described in U.S. Patent No. 2,950,048, granted on August 23, 1960.
Terminal verification results. Terminal verification results (TVR) or Tag '95' [1] is an EMV data object . The TVR is a series of bits set by the terminal reading an EMV card, based on logical tests (for example has the card expired). This data object is used in the terminal's decision whether to accept, decline or go on-line for a payment ...

Address verification service. An address verification service ( AVS) is a service provided by major credit card processors to enable merchants to authenticate ownership of a credit or debit card used by a customer. [1] AVS is done as part of the merchant's request for authorization in a non-face-to-face credit card transaction.
Verification and validation. Verification and validation (also abbreviated as V&V) are independent procedures that are used together for checking that a product, service, or system meets requirements and specifications and that it fulfills its intended purpose. [1] These are critical components of a quality management system such as ISO 9000.
A card security code ( CSC; also known as CVC, CVV, or several other names) is a series of numbers that, in addition to the bank card number, is printed (but embossed) on a credit or debit card. The CSC is used as a security feature for card not present transactions, where a personal identification number (PIN) cannot be manually entered by the ...
A BLS digital signature, also known as Boneh–Lynn–Shacham [1] (BLS), is a cryptographic signature scheme which allows a user to verify that a signer is authentic. The scheme uses a bilinear pairing for verification, and signatures are elements of an elliptic curve group. Working in an elliptic curve group provides some defense against index ...
