CardIO for flutter

core_card_io

CardIO plugin for flutter

A Flutter plugin for iOS and Android for scanning credit cards using the camera. This uses the CardIO library for iOS and Android

Note: This plugin is still under development, and some APIs might not be available yet. Feedback and pull requests are welcome!

Installation

First, add core_card_io as a dependency in your pubspec.yaml file.

iOS

Add the following key to your Info.plist file, located in <project root>/ios/Runner/Info.plist:

NSCameraUsageDescription - Set the value to be a string describing why your app needs to use the camera (e.g. "To scan credit cards."). This string will be displayed when the app initially requests permission to access the camera.

Run 'pod install'

Android

Add the following permission to your Android Manifest, located in `/android/app/src/main/AndroidManifest.xml:

<uses-permission android:name="android.permission.CAMERA"/>

Add card.io's open source license acknowledgments to your app's acknowledgments.

Example

Show example folder

  Map<String, dynamic> details = await FlutterCardIo.scanCard({
    "requireExpiry": true,
    "scanExpiry": true,
    "requireCVV": true,
    "requirePostalCode": true,
    "restrictPostalCodeToNumericOnly": true,
    "requireCardHolderName": true,
    "scanInstructions": "Hola! Fit the card within the box",
  });

Can anybody help me?

Release build

Hello

Can you build in release mode?
I'm trying to build, no errors, but was I tried to opened the APK on android smartphone, the app just closes.

Can you have any idea to fix?

Thanks
Guilherme

Custom styling

Will it be possible in future to style the 'Keyboard...' button?

Support for Android v2 embedding

To avoid unexpected runtime failures, or future build failures in future, this plugin needs to start supporting Android V2 embedding

Update Readme

The example given in Readme contains FlutterCardIo. Please update it to CoreCardIo

can't read Amex card

hello! does it scan Amex card by the plugin's camera?
like 3400 0000 0000 009
It can't put manually by keyboard.

Compilation error with Android X

Please remove or update Kotlin version in the build.gradle to minimum 1.3.0 otherwise the compilation fails when Flutter app is migrated to Android X

Diner's Club supported?

hello! does it scan Diner's Club card by the plugin's camera?
like 3600 000000 0000
It can't put manually by keyboard.

Scan result does not reset between calls to CoreCardIo.scanCard on iOS

Due to the way the iOS plugin is implemented, allocating the view controller upon plugin registration, the view controller does not reset on subsequent calls to CoreCardIo.scanCard.

My proposed solution is to allocate the view controller upon every call to scanCard.

Disclaimer: I have not tried this on the Android version, but from the code it seems like the activity is restarted from scratch every time you call scanCard.

EDIT: I see that there's already a fork that fixes this problem. Maybe it can be merged into this main dev branch?
