Hidden Gingerbread Code Shows NFC Write Capabilities Already Available [VIDEO]


We know NXP’s near-field communication chip inside the Nexus S will soon have write capabilities by way of a software upgrade, but a new video has been uncovered by NFC World suggesting that the functionality is already in place, and that it works.

Argentina-based Gibraltar discovered this by taking a look at Android’s kernel source and discovering @hide tags that are used to mask the functionality from SDK users.

While they were able to uncover it for the time being, he says that the APIs can change at any time as they are meant to be private and not for public use – don’t be surprised if this functionality ends up broken tomorrow. Take a look at the video below to see how they are able to overwrite an existing tag with one of their own using an application they built. [Thanks, Mike!]

The "Google Phone" sounded too awesome to pass up, so I bought a G1. The rest is history. And yes, I know my name isn't Wilson.

  12. This demo was made with an R/W tag, and the tags like those used in Google Places are configured to be read only, so no easy hack possibilites. Furthermore, NFC Fourm has released a Signature Record Type Definition specification that can be used to protect the integrity of a tag.
