Topaz512 NFC Transpoder

Why Topaz?
Our Topaz NFC tags are higher capacity NFC tags that are compatible with all NFC-enabled smart phones. With more memory, you’re able to program each NFC tag to perform more actions. Almost 300% more memory than regular NTAG203 NFC tags.

This is a Type 1 NFC tag and is compatible with the vast majority of current mobile phones. Because it is also compatible with BlackBerry’s, the Samsung Galaxy S4 and Google’s Nexus 4/new 7/10, it is a very good alternative to NXP’s Mifare 1k tag (which isn’t compatible). It’s good memory capacity does make it particularly suitable for vCards and it can be encoded with all the typical Android apps without problem. We would however generally recommend that unless you need the additional memory, the NTAG203 is our preferred choice of chip.
