Generic helpers for card number, expiry and CVV validations
Import the library and initialize card object.
Install from npm:
npm i @juspay/simple-card-validator --save
var cardValidator = require('simple-card-validator');
Or, you can simply use the file from dist/validator.js
if you are not using node/npm.
var card = new cardValidator('4242-4242-4242-4242');
card.getCardDetails();
This would output, card brand and different validation outputs like below:
{ card_type: 'visa',
valid: true,
luhn_valid: true,
length_valid: true,
cvv_length: [ 3 ],
gaps: [ 4, 8, 12 ],
supported_lengths: [ 16 ],
max_length: 16 }
Field | Description | Type |
---|---|---|
card_type | The card issuer for the provided card | String |
valid | Are the card details valid | Boolean |
luhn_valid | Is the card number valid | Boolean |
length_valid | If the card number length is valid | Boolean |
cvv_length | If the CVV/CAVV length is valid | Array [ Integer ] |
gaps | Gaps for UI as printed in cards | Array [ Integer ] |
supported_lengths | Supported lengths for the card type | Array [ Integer ] |
max_length | Maximum length for the card type | Integer |
To simply validate a card, call:
card.validateCard();
The result will be a validity boolean.
For validating expiry date,
card.validateExpiry('12/2018');
Additionally, the base date can be set for expiry validations. The base month and date can be provided by using,
card.setBaseDate(month, year);
eg: card.setBaseDate('02', '2016');
For validating CVV, use:
card.validateCvv(111);
CVV will be validated based on the brand of the card.
