Tapping an NFC tag and seeing a familiar website can feel convincing. It is not, by itself, proof that the product is genuine. A web address is public information. It can be copied into another NFC tag, printed as a QR code or shared as an ordinary link.
Secure NFC adds a check of the secure label to the product page. Customers can see the result, compare the displayed model or size with the item they hold and find out whom to contact if something does not match.
The important distinction: content access versus product verification
Both start with a tap. One simply opens information; the other also shows the result of a check.
A static NFC link
The tag stores a fixed destination. Any compatible tag can be programmed with the same destination, so reaching the page proves only that the phone read that address.
A verified NFC interaction
After tapping the secure label on a product, the customer can see the result of that check and compare the displayed product name and specifications with the item in hand.
What does the customer see when they tap?
The journey from picking up a product to seeing the result should be easy to follow.
- 01
Tap the label
Hold a compatible NFC phone near the marked area on the product.
- 02
Start the check
The phone opens the verification page provided by the brand.
- 03
Check the secure label
The service checks whether the secure label passes verification.
- 04
Compare the product details
The page shows the registered product information, ready to compare with the item in hand.
- 05
Use the brand service
The customer can continue to instructions, after-sales support or other brand content.
What secure NFC can do for customers
NXP® NTAG® 424 DNA and NTAG® 424 DNA TagTamper can support different secure NFC solutions. For the brand, the useful question is what customers can do with them.
Check a secure label
The service verifies the secure label as well as opening a product page.
Find the right product information
Customers can compare the model, size or specification with the item they have bought.
Recognise a used verification link
An old link is not a new product check. The page should ask the customer to tap the label again.
Check the seal
A suitable opening-detection seal can display the state detected when it is read.
What happens when someone copies the visible information?
A web address is easy to copy. An old link or screenshot should not lead a buyer to believe that the product they hold has just passed a check.
Copying an address
An address can be copied, but opening it is not a fresh check of the product in front of you.
Opening an old link
Tap the product again. An old page or screenshot does not show the current result for the item in hand.
Moving a genuine label
A genuine label moved to another item can still mislead a buyer. Suitable tamper-evident and transfer-resistant construction remains important.
Why physical product integration remains part of security
A label needs to suit the product as well as support verification. A full bottle, a garment washed repeatedly and a package in transit place different demands on it. BrandGuard evaluates reading and attachment on the actual item.
An opening-detection seal can help a customer notice that packaging has been opened. The protected opening and whether the label remains readable afterwards need checking on the finished package, rather than assuming them from a chip name.

What BrandGuard adds beyond the chip
BrandGuard can bring together labels, product information and online verification, helping a brand move from sample trials to everyday use.
Choose a label for the product
Consider the packaging, materials and everyday use, so the label is easy to read and suitable for attachment to the item.
Match the product information
Match each label with the agreed product name, model and details, then check the finished items before delivery.
Prepare the customer service
Agree the result messages and guidance, try samples, and plan production and support for questions that arise later.

Frequently asked questions
Is NFC itself an anti-counterfeiting technology?
Not necessarily. A basic NFC label may simply open a web address. A product protection solution also needs a secure label that can be checked, the right product information and suitable protection against transfer.
Can an NFC link be copied?
Yes. An address can be copied, but a copied link is not a new check of the product. Customers should tap the label on the item in hand and look at the result of that check.
Does secure NFC verification require an app?
An option without a dedicated app is possible. A customer taps with a compatible NFC phone and sees the result in the browser. Try the intended phone experience with samples before launch.
What does encrypted authentication add?
It helps verify the secure label and reduces the value of simply copying an identifier or web address. Appropriate attachment is also needed to make label transfer harder.
Can secure NFC report that a package has been opened?
With a suitable opening-detection seal, customers can see the seal state detected during a read. The result needs confirming on the actual packaging.
