Samsung announced today that it is updating TecTiles, its programmable NFC tags, to version 2. The latest version of the TecTiles will work with the Galaxy S 4, as well as older NFC-equipped Samsung phones.
TecTile stickers have a small NFC receiver that sends a signal to your smartphone. This signal then triggers an action on your phone such as opening an app, adjusting phone settings, or updating a status on Facebook or Google+.
You can buy TecTiles 2 from Samsung.com today and from retailers in June. Each pack costs $14.99 and includes five stickers. The Samsung TecTile Android app is available for free from Google Play.
