How to understand RFID technology in seconds, let’s look at these three aspects

  Three types

  There are three main categories of products derived from RFID technology:

  1. Passive RFID products: This type of product requires close contact identification, such as meal cards, bank cards, bus cards, and ID cards. The types of these cards require close contact during work identification. The main operating frequencies are: Low frequency 125KHZ, high frequency 13.56MHZ, ultra high frequency 433MHZ and 915MHZ. This type of product is also relatively common in our lives, and it is also a product that has been developed relatively early.

  2. Active RFID products: This type of product has the characteristics of long-distance automatic identification, so it is correspondingly applied to some large-scale environments, such as smart parking lots, smart cities, smart transportation, and the Internet of Things. Their main tasks are There are microwave 2.45GHZ and 5.8GHZ, UHF 433MHZ.

  3. Semi-active RFID products: as the name implies, it is a combination of active RFID products and passive RFID products. It combines the advantages of both, and under the trigger of the low frequency 125KHZ frequency, allows microwave 2.45G to play its advantage and solves the problem of active RFID products. And passive RFID products can not solve the problems, such as access control management, regional positioning management and security alarm applications, close-range activation positioning, long-distance data transmission.

  Six areas

  RFID technology has the characteristics of strong anti-interference and no need for manual identification, so it is often used in some fields that need to collect or track information, including but not limited to the following seven points:

  1. Warehouse/transportation/materials: Embed RFID chips into the goods, store them in warehouses, shopping malls and other goods and during the logistics process. The relevant information of the goods is automatically collected by the reader and the manager can quickly query the information of the goods in the system to reduce discarding or The risk of theft can increase the delivery speed of the goods, increase the accuracy rate, and prevent the fleeing of goods and anti-counterfeiting.

  2. Access control/attendance: For some companies or some large conferences, by entering the identity or fingerprint information in advance, they can identify the sign-in by themselves through the door recognition system, which saves a lot of time in the middle, which is convenient and labor-saving.

  3. Fixed asset management: Some places with huge assets or valuable items, such as libraries, art galleries, and museums, need complete management procedures or rigorous protection measures. When the storage information of books or valuables changes abnormally, The administrator will be reminded in the system as soon as possible to deal with the relevant situation.

  4. Train/vehicle identification/baggage security inspection: my country’s railway vehicle dispatching system is a typical case, which automatically identifies vehicle numbers and information input, saving a lot of time for manual statistics and improving accuracy.

  5. Medical information tracking: case tracking, waste product tracking, drug tracking, etc. are all good ways to improve hospital service levels and efficiency.

  6. Military/National Defense/National Security: The dynamics of some important military drugs, guns, ammunition or military vehicles need to be tracked in real time.
