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.
Magnetic Track Parser, a Java library to parse magnetic track data; Credit Card Track Data Parser, a Javscript library is for parsing credit card track data such as might be returned from a USB card reader; magnet, a Ruby library for decoding the track data on magnetic stripe cards
The final digit of a Universal Product Code, International Article Number, Global Location Number or Global Trade Item Number is a check digit computed as follows: [3] [4]. Add the digits in the odd-numbered positions from the left (first, third, fifth, etc.—not including the check digit) together and multiply by three.
The main idea behind the extension is that the full set of valid input characters is mapped to a list of code-points (i.e., sequential integers beginning with zero). The algorithm processes the input string by converting each character to its associated code-point and then performing the computations in mod N (where N is the number of valid ...
It was created to better control cardholder data and reduce credit card fraud. Validation of compliance is performed annually or quarterly with a method suited to the volume of transactions: [1] Self-assessment questionnaire (SAQ) Firm-specific Internal Security Assessor (ISA) External Qualified Security Assessor (QSA)
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile.

ISO 8583 is an international standard for financial transaction card originated interchange messaging. It is the International Organization for Standardization standard for systems that exchange electronic transactions initiated by cardholders using payment cards.
A major limitation for the validation of existing fraud detection methods is the lack of public datasets. [21] One of the few examples is the Credit Card Fraud Detection dataset [22] made available by the ULB Machine Learning Group. [23]
