String chinaUnionPayNumber = CreditCardFactory.RandomCardNumber(CardIssuer.ChinaUnionPay) GitHub - asu2sh/credit-card-validator: This program uses the Luhn Algorithm to validate a CC number. The program works for all popular cards like Visa, Amex, MasterCard etc. String masterCardNumber = CreditCardFactory.RandomCardNumber(CardIssuer.MasterCard) This program uses the Luhn Algorithm to validate a CC number. String amexNumber = CreditCardFactory.RandomCardNumber(CardIssuer.AmericanExpress) The following calculator determines the card issuer using Credit card issuers handbook or Major. string visaNumber = CreditCardFactory.RandomCardNumber(CardIssuer.Visa) and single validation digit, calculated by Luhn algorithm. Generates random credit card numbers of a specific CardIssuer. Issuer identification number (IIN) The first six digits of. Digits 7 to final number minus 1 indicate the individual account identifier (the last is the checksum). Usage CreditCardDetector CreditCardDetector detector = new CreditCardDetector("4012 8888 8888 1881") ĭetector.CardNumber // => 4012888888881881ĭetector.IsValid(CardIssuer.Maestro) // => Falseĭetector.IssuerCategory // => Banking and financial The credit card number entered passed the Luhn Check so it is a valid credit card number The credit card number entered failed the Luhn Check. The following card issuers are supported: It can also generate random credit card numbers for testing purposes. This is what Zend Framework uses as well.CreditCardValidator helps you validate credit card numbers, identify its issuer (Visa, Mastercard, etc), verify length, prefixes and check it through the Luhn algorithm. This simple algorithm can check to see if a credit card number was accidentally mistyped. Luhn is known because MasterCard, American Express (AMEX), Visa and all credit cards use it. If a character is misread or badly written, then Luhn 's algorithm will detect this error. This is also how PAR files can repair corrupt damaged or even missing files.Ĭredit cards use a checksum algorithm called the, Luhn Algorithm, invented by Hans Peter Luhn. Luhn makes it possible to check numbers (credit card, SIRET, etc.) thanks to its control key (a digit which makes it possible to check the others digits). It also allows barcode readers the ability to “guess” what the barcode if part of the barcode got riped or damaged. ![]() If any digit is out of order or mistyped you can tell that the barcode is wrong based on this checksum. It also has other features like Luhn Algorithm Check, Major Industry Identifier, Issuer identification number, Personal Account Number that helps with validation too Also, Checkout the Free credit card generator. If you ever look at a EAN-13 UPC barcode (on all retail products) you will notice there is a digit outside of the regular set on the right. This tool will save you time, money, and frustration by helping you quickly identify if a customers credit card number is valid or not.
