The listing, Square Credit Card Reader // BNIP (iPhone, iPad, Android) has ended.
This is an adapter to work with the Square application fro reading credit cards on smart devices. It is absolutely brand new and in great shape, NEVER used. It can work with any Apple smart device (such as iPhones, iPads, iTouches, etc.) as well as Android phones. As far as I understand, it is a free application to download from the store. With this, you can easier pay for these on your smart devices.
