Description

Radio frequency card with identification indicator lamp

Technical Field

The utility model relates to a radio frequency card field, concretely relates to radio frequency card with identification indicator.

Background

Radio Frequency Identification (RFID) is a wireless communication technology that can identify a specific object and read and write related data by radio signals without establishing mechanical or optical contact between the identification system and the specific object.

The radio signal is used to transmit data from the tag attached to the article by means of an electromagnetic field modulated at a radio frequency to automatically identify and track the article. Some tags can obtain energy from the electromagnetic field emitted by the identifier during identification without a battery, and the tags themselves have a power source and can actively emit radio waves (electromagnetic field tuned to radio frequency). The tag contains electronically stored information that can be identified within a few meters. Unlike bar codes, radio frequency tags need not be in the line of sight of the identifier, but can be embedded within the tracked object. Radio frequency identification technology is used in many industries. By attaching the tag to a vehicle in production, the manufacturer can track the progress of the vehicle on the production line. The warehouse may track the location of the drugs. The radio frequency tag can also be attached to livestock and pets, so that the livestock and the pets can be positively identified (positive identification means that a plurality of livestock are prevented from using the same identity). The RFID identification card can allow employees to enter a locked building, and the RFID transponder on the automobile can also be used to collect fees on toll sections and parking lots.

The current radio frequency card can be divided into an active type and a passive type, as long as the power is active, and the common types are 433M, 2.4G and 5.8G.
