  • Easy to use: small size, easy to package, can be embedded in the product.
  • Durable: no mechanical failure, long life, and resistant to harsh environments.
  • Sensing effect: much better than the general one.


What are the classifications of RFID labels?

There are mainly the following types of RFID labels:

  • Active RFID:Active RFID labels have their own power source, usually a battery.
  • Passive RFID:Passive RFID labels receive power from a reading antenna, whose electromagnetic waves induce a current in the antenna of the RFID label.
  • Semi-passive RFID labels:which means that the battery runs the circuit, while the communication is powered by the RFID reader.
  • Smart labels:These are simple RFID label These labels embed the RFID label in an adhesive label with a barcode. They can also be used by RFID and barcode readers. Smart labels can be printed on demand using a desktop printer, while RFID labels require more advanced equipment.


What types of RFID systems are there?

There are three main types of RFID systems: low frequency (LF), high frequency (HF), and ultra high frequency (UHF, microwave RFID is also available. Frequencies vary greatly between countries and regions.

  • Low frequency RFID systems:Frequencies range from 30 KHz to 500 KHz, but a typical frequency is 125 KHz. LF RFID has a shorter transmission range, typically from a few inches to less than six feet.
  • High frequency RFID systems: Frequencies range from 3 MHz to 30 MHz, with a typical HF frequency of 13.56 MHz. The standard range is from a few inches to a few feet.
  • UHF RFID systems:Frequencies range from 300 MHz to 960 MHz, with a typical frequency of 433 MHz, and are generally readable at distances of more than 25 feet.
  • Microwave RFID systems:These systems operate at 2.45 Ghz and can be read from more than 30 feet away.


RFID label application areas


  • Military logistics system RFID

RFID technology automatically identifies targets and quickly collects data through wireless radio frequency signals, without human intervention, and can simultaneously identify multiple high-speed moving targets, suitable for various environments. This technology has the characteristics of high-speed data transmission, intelligent reading and writing, encrypted communication and information security, providing efficient, safe and controllable technical support for military logistics systems.


  • Access control security

The future access control system will widely adopt radio frequency card technology, and one card will integrate multiple functions such as work permit, access permit, parking, accommodation and travel passport. Simplify the access process, improve efficiency, and strengthen security management.


  • Car anti-theft

The car anti-theft system uses RFID technology, and the radio frequency card is encapsulated in the car key. When the key is inserted into the ignition, the RFID reader verifies the key identity. If the correct signal is not received, the engine will not start, thereby preventing illegal startup and short-circuit ignition.


  • Electronic goods monitoring system

The electronic goods monitoring system effectively prevents theft of goods through the cooperation of radio frequency cards and RFID readers. It consists of an activated radio frequency card and an RFID reader at the store exit. When the goods leave the store without checking out, the system detects the RFID card and triggers an alarm to alert the store clerk and security personnel. The system can remove the alarm by removing, deactivating the magnetic field or destroying the RFID card. It is widely used in the retail industry to protect the safety of goods.
