RFID technology is a non-contact information exchange technology using radio frequency identification technology. ‌ The basic components include:
RFID electronic tag ‌, which is composed of coupling element and chip, ‌ contains a built-in antenna, ‌ is used for communication with radio frequency
antenna. ‌RFID reader, ‌ A device that reads (‌ can also be written in the read/write card) ‌RFID tag information. ‌
An RFID antenna transmits radio frequency signals between RFID tags and RFID readers.

If the packaging is opened during the transportation of fresh products, it is easy to cause deterioration or damage to fresh products. Therefore,
RFID anti-opening sensor tags came into being.

The RFID anti-opening sensor tag consists of an RFID chip and a flexible foldable dipole antenna. The dipole antenna is divided into two parts, located
on the inside of the top of the package, parallel to each other, and when the packaging seal is complete, the two parts of the antenna cancels the signal
of each other, and the RFID reader cannot receive the transmission signal of the RFID tag; When the package is opened, the signal is transmitted normally,
and the RFID reader can read the information of the RFID electronic label, so as to realize the integrity detection of the food packaging. ‌ ‌
