Credit card scanning for mobile apps

Yes, that's right: the card.io library for iOS is now open-source!

This repository contains everything needed to build the card.io library for iOS.

What it does not yet contain is much in the way of documentation. 😿 So please feel free to ask any questions by creating github issues -- we'll gradually build our documentation based on the discussions there.

Note that this is actual production code, which has been iterated upon by multiple developers over several years. If you see something that could benefit from being tidied up, rewritten, or otherwise improved, your Pull Requests will be welcome! See CONTRIBUTING.md for details.

Using card.io

If you merely wish to incorporate card.io within your iOS app, simply download the latest official release from https://github.com/card-io/card.io-iOS-SDK. That repository includes complete integration instructions and sample code.

If you use CocoaPods, then add this line to your podfile:

pod 'CardIO'

If you use Carthage, then add this line to your Cartfile:

github "card-io/card.io-iOS-source"

You must also have an SSH key setup with GitHub so that the dmz submodule will download properly. See the documentation here for directions.

Dev setup

clone this repo, including its dmz submodule: git submodule sync; git submodule update --init --recursive
requires Xcode 5+ (toolchain for iOS 7)
requires Python 2.6+
for building releases, requires pip and fabric

Python

We use Python-based build scripts.

If you are using virtualenv and virtualenvwrapper, create a virtual environment (optional but recommended):

# Create virtual environment for Python
mkvirtualenv cardio

Install required Python dependencies (this command may require sudo rights if installing globally):

# Install required dependencies
pip install -r pip_requirements.txt

Baler

We use baler (included in pip_requirements.txt) to encode assets (strings and images) within our library. Create a .baler_env file in the top project directory, and set the $PATH environment variable to include where you installed baler. Examples:

    # Create a .baler_env, specifying the correct path for an installation using virtualenv
    echo 'export PATH=$PATH:~/.virtualenvs/cardio/bin' > .baler_env
    
    # - OR -

    # Create a .baler_env, specifying the correct path if not using virtualenv
    echo 'export PATH=$PATH:'`dirname \`which bale\`` > .baler_env

card.io-dmz

The card.io-dmz submodule (included here in the dmz directory) includes the core image-processing code.

Normal development

Use Xcode in a normal fashion to build the library. The project's icc target is a demo app which will allow you to exercise the library in various ways.

Unofficial card.io-iOS-SDK release

How to make a Release build of the library for your own use:

Run fab build:outdir=~ (or specify some other output directory).
