What is the use of electronic room card in Jinjiang Hotel?
Hotel room card is a kind of RFID technology, which is used to control, detect and track objects.
The system consists of an interrogator (or reader) and many transponders (or tags).
At present, RFID technology is widely used, such as library, access control system, food safety traceability and so on. The basic working principle of RFID technology is not complicated: after the tag enters the magnetic field, it receives the RF signal sent by the reader, and sends out the product information (PassiveTag) stored in the chip with the energy obtained by the induced current, or the tag actively sends out a signal with a certain frequency (ActiveTag or active tag), and the reader reads and decodes the information and sends it to the central information system for relevant data processing.
With the electronic key card, the hotel can control the room more actively, even if the guest does not return the key card to the front desk, it will not affect the next guest's stay.
