Description:

DatPayment is a lightweight JS library used to create an interactive payment form that enables the user to type credit card information in a convenient way. Requires the familiar Stripe.js library.

Features:

  • Auto swaps credit card image based on your input.
  • Formats credit card numbers.
  • Validates the credit card numbers and expiration dates.

How to use it:

Place the core style sheet DatPayment.css in the head section of the html page.
