Is it somehow possible, to use the built-in NFC-functions from Android with the external USB reader? Is there another library for this reader, that supports peer-to-peer communication with other NFC-devices? The built-in NFC library in Android 2.3 and 4.0 only supports the PN544 NFC chip by NXP Semiconductors. I don't think there are any card readers on the market that use it, as this chip is specifically designed for use in mobile devices. You may be able to find alternative implementations of the Android NFC API that support other NFC chips, though.Utility for the ACR 122U NFC Reader.

Android-powered devices with NFC simultaneously support three main modes of operation: Reader/writer mode, allowing the NFC device to read and write passive NFC tags and stickers. P2P mode, allowing the NFC device to exchange data with other NFC peers.Library for interaction with ACS NFC readers over USB; external NFC support Android devices. Features: External NFC reader management and interaction; Parallell use of external and/or internal NFC (i.e. in the same activity, both enabled at the same time) Support for both tags and Android devices (Host Card Emulation), simultaneously I have to make an app where I have to use external USB NFC device to read and write data to NFC tags and also p2p between that reader and android nfc phones. I have a NFC device ACR1222L. I also downloaded the android library from http://android.acs.com.hk/ The library comes with a demo project.
