Right now I am having Tablet having OS Android 2.3.3 instead of NFC phone,so I need to connect External card reader to tablet.Please tell me which card reader should I prefer and any driver needed to connect card reader to tablet. The inbuilt NFC libraries support to that reader or not? thanks in advance.
I found an answer,the ACS now provides android library and sample application for their readers.You can find library here and some information and video demo of android supported readers is here.
The only problem is that ACS android library supports only Android 3.1 and above. hope it will help you.
If you still have question feel free to ask..
