card

Card is a JavaScript library that adds an animated, realistic credit card graphic to any payment form on a website. As a user types their card number, name, expiry date, and security code into the form fields, a visual card on screen updates in real time to reflect what they are typing. The card image even flips over to show the back when the user moves to the security code field.

The library works with plain JavaScript or with jQuery and requires just one line of code to attach it to an existing form. You point it at your form and a container element where you want the card visual to appear, and the library handles the rest. It generates everything using CSS and HTML, so no image files are needed.

Card supports several customization options: you can set the width, override the placeholder text, change the date format labels, and provide translations into other languages. For forms that split first name and last name into two separate fields, Card can combine them into a single displayed value on the card graphic.

Wrappers are available for popular JavaScript frameworks including Angular, React, Vue, and Ember, so teams using those can integrate the library without writing custom glue code. Installation is available through npm or Bower, and the README includes example code for each approach.

This project is a front-end visual enhancement aimed at making payment forms feel more polished and trustworthy. It does not handle payment processing itself; it is purely a user interface layer that sits on top of whatever payment system a site already uses.
