How to achieve the anti-counterfeiting function for IOS based on the NFC tag

[long19890829]

As we know, the ios can only read the ndef message, and the ndef message is in the public area and is unencrypted, therefore, how could we identify the NFC tag is unique and is not a copy one, (except using the UID). Even, can we put a private key into the tag and the ios can get it, do you have a solution for this problem, and give us some advises.

One more question, for ICODE tag(Type 5, 15693), we would like to confirm which tag(specific model) support the UID and counter mirror features(mapping the UID and counter value into the ndef area);

looking forward your reply, and thank you very much!

Dear long zhu,

as you know IOS only supports reading to tags, and only to NDEF formatted tags, maybe you can store the UID as an NDEF text value and then read it, Until Apple supports more on NFC there not much that we can do here. please contact apple for more details on the NFC in IOS,  the following devices have UID please check the datasheets for more information on them.

ICODE DNA SL2S6002FUD

ICODE SLIX 2 SL2S2602

ICODE SLIX SL2S2002 / SL2S2102

ICODE SLIX-L SL2S5002 / SL2S5102

ICODE SLIX-S SL2S5302 / SL2S5402
