Abstract (en)

The NFC-based tag includes a substrate, a first and second coils formed on the substrate and an NFC chip fixed on the substrate. A status code whose default value is 0 is stored in memory of the NFC chip. The first coil is connected to the NFC chip and serves as an antenna thereof. The NFC chip communicates with an NFC reader through the first coil. The NFC reader can read or write the status code through the first coil. The NFC chip has an IO contact and a grounding contact. The IO contact connects to the grounding contact via the second coil. The second coil serves as an EAS coil. The IO contact is connected to the grounding contact through the second coil to form a closed loop. The NFC reader rewrites the status code to be 1 irreversibly when the second coil is broken or has finished checkout.
