React Native Credit Card Input

Easy (and good looking) credit-card input for your React Native Project ūüí≥ ūüí≥

Code:

<CreditCardInput onChange={this._onChange} />
// or 
<LiteCreditCardInput onChange={this._onChange} />

Features

  • Skeuomorphic credit-card ūüí≥ (inspired by: card, react-native-credit-card)
  • !!NEW!! Now you could scale the Credit Card for smaller screens
  • !!NEW!! Now you could use CardView as a Component. example use case: showing saved payment details, etc.
  • Lite version for smaller screens (or if skeuomorphic is not really your thing)
  • Credit-card input validations & formatting while you're typing
  • Form is fully navigatable using keypad
  • Works on both Android and iOS

Usage

npm i --save react-native-credit-card-input

then add these lines in your react-native codebase

import { CreditCardInput, LiteCreditCardInput } from "react-native-credit-card-input";
 
<CreditCardInput onChange={this._onChange} />
// or 
<LiteCreditCardInput onChange={this._onChange} />
 
// Note: You'll need to enable LayoutAnimation on android to see LiteCreditCardInput's animations 
// UIManager.setLayoutAnimationEnabledExperimental(true); 
 

And then on your onChange handler:

_onChange => form => console.log(form);
 
// will print: 
{
  valid: true, // will be true once all fields are "valid" (time to enable the submit button) 
  values: { // will be in the sanitized and formatted form 
   number: "4242 4242",
   expiry: "06/19",
   cvc: "300",
   type: "visa", // will be one of [null, "visa", "master-card", "american-express", "diners-club", "discover", "jcb", "unionpay", "maestro"] 
   name: "Sam",
   postalCode: "34567",
  },
  status: {  // will be one of ["incomplete", "invalid", and "valid"] 
    number: "incomplete",
    expiry: "incomplete",
    cvc: "incomplete",
    name: "incomplete", 
    postalCode: "incomplete",
  },
};
 
// Notes:  
// cvc, name, & postalCode will only be available when the respective props is enabled (e.g. requiresName, requiresCVC)

Methods

setValues

Set values into credit card form

    // sets 4242 on credit card number field 
    // other fields will stay unchanged 
    this.refs.CCInput.setValues({ number: "4242" });

Known issues: clearing a field e.g. setValues({ expiry: "" }) will trigger the logic to move to previous field and trigger other kind of weird side effects. PR plz

focus

focus on to specified field

    // focus to expiry field 
    this.refs.CCInput.focus("expiry");

Example

In the example directory, run:

npm install
 
react-native run-ios
# or
react-native run-android

Future Improvement

Breaking Changes from 0.2.*

  • cardViewSize prop are removed from CreditCardInput, use cardScale instead (because changing the size will break most of the texts)
  • bgColor prop are removed from CreditCardInput, ask your designer friend to make a credit card image instead (or use the prebundled image)
  • imageFront and imageBack props are renamed to cardImageFront and cardImageBack respectively,
  • Android monospace fonts doesn't looks as nice as iOS Courier, bundle custom fonts into your app and override the default using cardFontFamily instead
