NFC chips enable contactless data transfer, which is widely used in bankcards and transport cards. Their major advantage? All recent smartphones are equipped with an NFC reader, and they don't need a battery, offering unlimited battery life. So they're the best way to interact with a product. But the question remains: are they really safe?
In principle, NFC chips are unique and virtually impossible to duplicate. In reality, it is still technically possible to make copies.
At Legitag, we go one step further: all product information is stored and secured via our ChainContract blockchain. In fact, copying a chip without accessing the encrypted data is pointless, as the copy becomes unusable.
