Topaz 512 NFC forum type 1 tag which 13.56MHz Near Field communication tag/ identification Read/write NFC card. It is working to the ISO/IEC 18092, ISO/IEC21481 and ISO/IEC 14443A standards.
The topaz 512 card is a two terminal device designed to be connected a loop antenna to produce a passive NFC/RFID tag operating in standard unlicensed 13.56MHz frequency band.
The read/write data within the Topaz IC memory is EEPROM-based, allowing individual blocks to become locked into read only operation by contactless command. Once locked, to obtain the vehicle irreversible.
The Topaz IC is based on an actual physical EEPROM array sized 120 bytes.
Passive operation implies that no battery is needed because the Topaz IC gathers its operational energy from the interrogation field generated from the NFC Reader/Writer unit.
NFC card, or near-field communication, is an easy and intuitive technology that allows you to use your mobile phone for special purposes. An NFC tag can share and link to information such as web pages, social media and all other sorts of other information generally. Other areas where NFC card is starting to evolve into are making payments, opening doors secured with contactless locks, logging on to computers and many more. All of these actions have something in common, that is they invoke an action based on you placing your phone (or any other NFC device) near (the N in NFC) the thing you want to read or interact with.
NFC is bridging the gap between both the physical and virtual worlds. By bringing two devices near each other, there is a virtual reaction. Bluetooth and WiFi do not have this ease in set up. So the key feature of NFC card is: It is automatic! There is no need to launch an application!
Topaz IC can be used in NFC Forum Tags/Smartposter/ One-touch Setup applications and also general RFID
-Focused on operation with NFC devices which attempt to ISO/IEC 18092 (NFCIP-1) and/or ISO/IEC 21481 (NFCIP-2)
Protection for data throughout the write operation from the Topaz IC only responding to commands prepended with a matching UID. This also provides protection from the situation where there are multiple tags from the reader field
