I'm exploring the possibilities of using the NFC Antenna on my Nexus 4 to read membership cards at work. The cards are an EM4102 RFID tag.
I found a small app called NFC Reader on the Android Market, but it doesn't react to the card, but it reads another tag (Mifare I think) perfectly fine.
Would this be a miss in the software, or is the antenna unable to read EM4102 tags?
I'm working on a small test app to see if I can get it working, but if anyone here has any experience with this, it'd be much appreciated!
I don't have experience with those tags, but a quick Google search suggests they are 125kHz technology. NFC only supports 13.56MHz technology.
