Android rfid reader - what is RFID?

RFID radio frequency identification: it is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not need manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and multiple electronic tags at the same time, which is fast and convenient to operate.

Basic working principle of RFID Technology: after the tag enters the magnetic field, it receives the RF signal sent by the interpreter, and sends the product information stored in the chip (passive tag or passive tag) with the energy obtained by the induced current, or the tag actively sends the signal of a certain frequency (active tag, active tag or active tag). After reading and decoding the information, the interpreter sends it to the central information system for relevant data processing.

RFID advantage: it is simple and practical, and is especially suitable for flexible application technology for automatic control. Can work freely in a variety of harsh environments: short-range RF products are not afraid of oil stains, dust pollution and other harsh environments, and can replace bar codes.

Android bluetooth rfid reader - what is RFID tag?

It is composed of coupling elements and chips. Each RFID tag has a unique electronic code, which is attached to the object to identify the target object, commonly known as electronic tag or smart tag.

Principle of RFID tag: after the RFID tag enters the magnetic field, it receives the RF signal sent by the interpreter and sends the product information (passive tag, passive tag or passive tag) stored in the chip with the energy obtained by the induced current, or actively sends the signal of a certain frequency (active tag or active tag); The interpreter reads and decodes the information and sends it to the central information system for relevant data processing.

Handheld rfid computer - classification of RFID tags

1. RFID tags are divided into active, passive, semi-active and semi-passive tags;

2. According to different frequencies, it can be divided into low frequency, high frequency, ultra-high frequency and microwave electronic labels;

3. According to different packaging forms, it can be divided into credit card, linear, paper, glass tube, circular and special-purpose special-shaped labels.
