Android RFID Reader Demo
This app requires that the USB Host(aka OTG) feature is enabled on your phone/tablet.
I had to root my own tablet to enable OTG.
The user interface consists of a scrollable text area for output from the RFID reader and a single scan "Read" button.
In continuous scan mode the button is disabled.
Scan mode, timing parameters and LED state are set in a preference activity launched from the Settings menu item.
I wrote this app as an educational exercise in the use of various features of the Android platform. It is a work in progress, so check the link for newer versions of the .apk file.
