Android Library/api For Nfc Reader/writers

Are there any existing libraries that will allow an Android tablet (4.0.4) without a NFC chip to interface with an external USB NFC reader/writer?

Solution 1:

Yes, the ACR 122 U can be connected via an USB OTG Cable. ACR has an Android test app on their driver page. You will in addition need something like NFC Tools for Java to interact with the reader (sending commands etc).

Solution 2:

Maybe default packages will help you. Otherwise you can look for any third-party libs
