Trikker-1k indoor labels and outrood tags contain inlay by UPM RFID and NXP Mifare Classic (Standard) 1k chip. This tag type's memory allows to set indivuidual keys for each sector (sector of of 4 blocks). There are KeyA and KeyB available for protection.
Each sector has 2 keys and 4 access bytes. The access bytes are used to set read and write access, and the information on which keys must be used for read and write.
Trikker-1k tag default key A = FF FF FF FF FF FF
Trikker-1k tag default key B = FF FF FF FF FF FF
Programming with Nokia 6131 NFC changes the keys. There are essentially 2 keys used for reading NDEF tags:
- keys used for the MAD area, which are: A0A1A2A3A4A5 (sector 0)
- keys used for the NDEF area, which are: D3F7D3F7D3F7 (sectors 1-n)
The best source for Mifare keys related information is the chip manufacturer NXP's web site (http://www.nxp.com/). The specifications include e.g. information on how to set access bytes.
ToP Tunniste delivers tags also with pre-programmed memory content, and content can be protected with customer specific keys and access settings.
For customers who aim to program NFC tags with NDEF records (e.g. web-links), we suggest ToP Encoder NFC tool. That includes reader device and easy to use Windows software to read, write, scan and write protect tags. ToP Encoder NFC is available at ToP Shop netstore.
