Parse track 1 from Magnetic Card Readers.
npm install tarot-js
var cc = new Tarot(...TRACK1STRING...);
cc.number // => 1234567812345678
cc.cardHolder // => John Doe
cc.expiration // => 0199 (mmyy)
You can pass it in the track 1 line or the full line set, Tarot will only parse track 1.
Can't seem to find a consistent way to parse CVV data across cards. Also, not all cards carry the CVV in the track line (or at least the unencrypted version). AMEX for example, doesn't seem to have the CVV number in the track line, or it's encrypted.
Great resource explaining the format here.
