All numbers are generated according to Luhn, a known algorithm, and provide valid card information according to this algorithm at various application stages.
The cardholderName validation essentially tests for a valid string greater than 0 characters in length that does not look like a card number. This virtual credit card creating app, generates randomly MasterCard, VISA, AMEX or Discover card numbers with name, CVV, zip code and fake money for testing and simulation works. Valid.cardholderName(value: string): object If a valid card type cannot be determined, the card field in the response will be null.Ī fake session where a user is entering a card number may look like: Input It is designed as a CommonJS module for use in Node.js, io.js, or the browser.

npm install card-validatorĮxample Using a CommonJS build tool (browserify, webpack, etc) Credit Card Validator provides validation utilities for credit card data inputs. You can install card-validator through npm. For example, if you detect a user is entering (or has entered) an American Express card number, you can update the maxlength attribute of your CVV input element from 3 to 4 and even update the corresponding label from 'CVV' to 'CID'.
Additionally, by having access to the current card type, you can better manage the state of your credit card form as a whole. This is useful for scenarios in which you wish to render an accompanying payment method icon (Visa, MasterCard, etc.). Conversely, if a user enters “41x” that value can no longer pass strict validation and you can provide a response immediately.Ĭredit Card Validator will also provide a determined card type (using credit-card-type). In a credit card field, entering “411” is not necessarily valid for submission, but it is still potentially valid.
It includes first class support for 'potential' validity so you can use it to present appropriate UI to your user as they type.Ī typical use case in a credit card form is to notify the user if the data they are entering is invalid. Credit Card Validator provides validation utilities for credit card data inputs.
