RFID Product Categories
There are roughly three categories of products derived from RFID technology: passive RFID products, active RFID products, semi-active RFID products.
The earliest development of passive RFID products, but also the most mature development, the most widely used products market. For example, bus cards, canteen meal cards, bank cards, hotel access cards, second-generation ID cards, which in our daily lives can be seen everywhere, are close contact type of recognition. The main working frequency of its products are low frequency 125KHZ, high frequency 13.56MHZ, ultra high frequency 433MHZ, ultra high frequency 915MHZ.
Active RFID products, developed slowly in recent years, its long-range automatic identification of the characteristics that determine its huge application space and market potential. There are major applications in areas such as smart prisons, smart hospitals, smart parking, smart transportation, smart cities, smarter planets and the Internet of Things (IoT) in the areas of automatic distance identification. Active RFID sudden emergence in this area, are long-distance automatic identification category. The main working frequency of products are ultra-high frequency 433MHZ, microwave 2.45GHZ and 5.8GHZ.
Active RFID products and passive RFID products, its different characteristics, determines the different application areas and different modes of application, but also have their own advantages. However, in this system, we focus on semi-active RFID products between active RFID and passive RFID. This product integrates the advantages of active RFID and passive RFID in access control, personnel precise positioning , Regional positioning management, perimeter management, electronic fence and security alarm and other fields have great advantages.
Semi-active RFID products, active RFID products and passive RFID products combine the advantages of 125KHZ frequency in the low-frequency trigger, let microwave 2.45G advantage. Semi-active RFID technology, also known as low-frequency activation triggering technology, uses low-frequency close-range precision positioning, microwave remote identification and upload data to solve the simple active RFID and passive RFID can not function. Simply put, it is close activation of positioning, remote identification and upload data.
