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.
Physical card transactions already commonly have what could be termed strong customer authentication in the EU (Chip and PIN), but this has not generally been true for Internet transactions across the EU prior to the implementation of the requirement, [1] and many contactless card payments do not use a second authentication factor.
Therefore, systems that pad to a specific number of digits (by converting 1234 to 0001234 for instance) can perform Luhn validation before or after the padding and achieve the same result. The algorithm appeared in a United States Patent [1] for a simple, hand-held, mechanical device for computing the checksum. The device took the mod 10 sum by ...

The Payment Application Data Security Standard (PA-DSS) is the global security standard created by the Payment Card Industry Security Standards Council (PCI SSC). [1] PA-DSS was implemented in an effort to provide the definitive data standard for software vendors that develop payment applications.
3-D Secure is a protocol designed to be an additional security layer for online credit and debit card transactions. The name refers to the "three domains" which interact using the protocol: the merchant/acquirer domain, the issuer domain, and the interoperability domain. [1]
This is different from the credit card Address Verification System (AVS), which is the method used by credit card processors to authenticate ownership of a credit card by verifying that the account on the credit card matches the billing address on file. Credit card AVS does not determine deliverability of an address.
A break point is an observation where anomalous behaviour for a particular account is detected. Both the tools are applied on spending behaviour in credit card accounts. A combination of unsupervised and supervised methods for credit card fraud detection is in Carcillo et al (2019). [18]
