A4C offers the Samsung TecTiles NFC Tag 5-Pack for Android Phones for $4.95 with free shipping. Although we saw it for 50 cents less three weeks ago, it's the lowest total price we could find now by $2. These tiles are compatible with Galaxy S3, S2, S, Note, Note 2, and possibly other older model phones. They can be customized to launch apps, send text messages, share contact information, or change phone settings when you're in a chosen room or office.
