NFC Tagwriter App

Posted on Feb 18, 2011 - By

As you may know, Google is pushing in the coming days an OTA update that adds read and write public APIs for the NFC chip. Well today, NXP launched  NFC Tagwriter, a free app for Android 2.3.3 using those features. This app allows to store contacts, URLs and text messages on any NFC tag


It only installs on devices with at least 2.3.3 version and NFC. Check it out

    I have a Nexus S with 2.3.3 and this still isn’t downloading for some reason. Any ideas?

  • Try again now. It’s seems that the xml with requirements was bad.

  • Elmar says:

    Sorry for too many questions, but it’s really exciting news:
    1) which RFID tags (specific brands?) is it compatible
    2) is there a possibility to share a codebase, and is it wirtten in java?
    3) also are you guys using to communicate with the RFID tag?

  • Elmar says:

    also, is there any plans to make the system ISO 18000-6C compatible (UHF chips)?

  • To Elmar,

    1) This is an specific NXP app, so you can use any mifare / desfire compatible tag.
    2) Ask NXP, they are the authors.
    3) I don’t think so, this app uses the android 2.3.3 api and lib-nfc from NXP.

  • Elmar,

    I don’t think so. This app is for NFC, so is using tags in the 13.56 MHz freq. ISO 18000-6C (EPC Gen2) tags operates in a higher frequency (860-960 MHz).

    Gustavo, thanks for the feedback, appreciate it!

    Hi Guys,

    I was hacking 2.3.1 API to write on some tags… without success… cause I don’t want to upgrade my Nexus S to 2.3.3.

    Is there anyone that has already done this upgrade?
