随着人的懒的助长及人的聪明程度提高,慢慢忘记笔,习惯了键盘操作或手写,慢慢我们进入扫描识别的都市里,

今天当你体验微信及支付宝扫描识别银行卡号方便准确性特别高;

github 上提供的资料有,

https://github.com/card-io/card.io-iOS-SDK

https://github.com/paypal/PayPal-iOS-SDK 等

如果是xcode5或者更新的版本,只需要添加下面的库 
* AVFoundation 
* AudioToolbox 
* CoreMedia 
* MobileCoreServices 
并且保证Build Settings里面这两项都是YES: 
* Enable Modules (C and Objective-C) 
*Link Frameworks Automatically

2、在TARGETS-Build Settings添加 -lc++到Other Linker Flags

(3)使用 
我是把它作为一个viewController类使用
