Does NTAG213TT fail to brand protection in this situation ??

[Liang]

Our company wants to use NTAG213TT to protect product from counterfeit. But wants to know first if NTAG213TT will fail in this situation?
1. A genuine NTAG213TT tag from us attached to a genuine product when came out from factory.
2. A hacker buy this product from store but did not read the tag.
3. Hacker cut the detection wire and take out the chip of NTAG213TT from tag very carefully.
4. Hacker rewire the wire very carefully, make it a good NTAG213TT tag again.
5. Hacker make the appearance of the tag same as it first came out.
6. Hacker adhere the tag to a counterfeit product.
We afraid when a customer bought the counterfeit product, reading the tag to check, our background server will never know this product is counterfeit, since the tag was not read before and the tag IC is genuine.

We think NTAG413 will also fail in this situation.
Could any one please tell us what is the unbreakable brand protection RFID tag from NXP?
Thanks!

Hi Liang,

An unpowered device cannot detect changes on an interface pin. This is physically not possible.

You should ensure that a manipulation breaks the wire inside of the packaging in an irreversible way. The construction of packaging should prevent any fixes of reconnection of the wire.

If the NTAG213TT is read in a field and the broken wire is detected, this state is saved irreversible and cannot be reset again.

Thanks for reply.

Can you suggest an irreversible way?

We have studied a lot, but didn't find a way to prevent to take out the chip (NTAG 213, NTAG 213TT) from the tag.

NTAG 213TT or NTAG 413 DNA will lose the function of "Brand Protection " due to take out the chip from tag is easy.

You said: "An unpowered device cannot detect changes on an interface pin. This is physically not possible."

Because the Physical properties of the passive tag, the hacker can destroy the tamper wire or antenna and re-wired it, before any reader or cellphone reading the tag, the hacker can then attach the modified tag to fake product and sell it, our background server will treat this tag as genuine tag from us.

Could you give us some suggestion to avoid this situation?

Thank you very much.

Hi Liang,

Did you read this AN (link below)?

AN11941 NTAG TagTamper products - Tamper loop design hints

In the NTAG213 flyer (link below) two part type numbers are given.

NTAG213 Tag Tamper

If you check the product numbers you will find the package and order site:

Direct order site

There is an email address where to get more detailed information:

eco-products@nxp.com

In your case it makes sense to use unpacked tags where the antenna and the protection wire is mounted in your factory.

We here on TapLinx site gives technical support for TapLinx and MIFARE, NTAG and ICODE products. But for special questions of packaging we must hand it over to our distributors who are able to find a package for you which fulfil your needs.
