In the scene of reading vehicle information and wireless charging, although the functions of RFID and ETC are the same, there are still many differences. Nowadays, in order to improve the efficiency of weighing, many companies that develop weighing software have introduced RFID weighing methods. So why is RFID now being used more than ETC?

The Difference Between RFID and ETC

  • Power supply: ETC is an active system, equipped with active chips, and needs to provide power support. RFID is a passive system and does not require additional power by programmable RFID vehicle tags.
  • Security level: The security level of RFID is higher, and its encryption method adopts the commercial secret SM7 algorithm with independent intellectual property rights. Realize anti-tampering, anti-disassembly, anti-copy.
  • The uniqueness of the signal: The biggest problem with ETC is that it cannot identify vehicle information, and there are often cases of rubbing ETC. RFID can identify vehicle information and is unique.
  • Life cycle: ETC needs electricity and has a lifespan of about 5 years. RFID works with the help of electromagnetic energy, and theoretically its lifespan can accompany the vehicle for life.

Vehicle RFID Weighing

Now many RFID companies that make weighing systems have begun to apply RFID to weighing and weighing to increase the speed of weighing.


The weighing site using RFID technology is more orderly and efficient. After the vehicle handles the electronic tag (electronic license plate), stick the tag on the front windshield, and it will be recognized when it passes the weighbridge. If the vehicle information is correct, it will start weighing, and if it is incorrect, it will not be weighed. It further improves the efficiency of weighing and promotes the process of enterprise intelligence.
