The
RFID reader is mainly composed of a read-write module and an antenna. The antenna's function is to wirelessly communicate with the
RFID electronic tag, while the read-write module is responsible for reading or writing tag identification codes and memory data. A series of tasks involved in this process, such as establishing communication, collision prevention, and identity verification, are all processed by
RFID readers. Next, let's take a detailed look at the main functions of
RFID readers?
What are the main functions of
RFID readers?
1. Provide energy for electronic tags
In passive or semi passive situations, tags require energy from
RFID readers to activate the
RFID electronic tag and read information.
2. Read and write tags
RFID readers access data from
RFID tags, including reading and writing data from
RFID electronic tags.
3. Information transmission
By using
RFID readers, the information of items can be read out, and communication with computers/higher-level systems can be achieved through some interfaces, providing information to the computer for data exchange between the system terminal and the information management center, thereby solving the data management and information analysis needs of the entire system.
4. Multi label recognition
RFID readers can correctly identify multiple
RFID electronic tags within their working range, and through built-in anti-collision algorithms, can exchange data with multiple electronic tags.
5. Realize mobile target recognition
RFID readers can not only recognize stationary objects, but also moving objects. As long as they enter the reading and writing range of the
RFID reader, they will automatically read the tag information within the range.
What are the applications of
RFID in daily life?
1. Clothing retail and catering
Clothing stores, high-end goods, catering, etc. all use
RFID technology. On the one hand,
RFID is used for automatic settlement, such as unmanned stores and catering automatic settlement counters; On the other hand,
RFID technology is also widely used in anti-theft and anti-counterfeiting. Jewelry stores, precious tobacco and alcohol, pharmaceuticals, etc. can all use
RFID for anti-theft and anti-counterfeiting; In addition, real-time sales data can be obtained through
RFID, which enables chain stores to replenish goods in a timely manner and know consumer preferences, providing data support for subsequent marketing.
2. Library and Archive Management
For the management of books, archives, assets, etc.,
RFID has more advantages than barcodes. Barcodes require unobstructed recognition and can only scan one barcode at a time. Moreover, barcodes are prone to contamination, which affects scanning and reading. For the inventory work of books and archives, it is inefficient and prone to errors.
RFID, on the other hand, can be used for batch identification and reading without contact or alignment with electronic tags. Electronic tags can be made in various styles and packaged with various materials, providing good protection and avoiding damage in daily life.
3. Bill, identification, ticket and luggage management, etc
For large and important conferences, personnel identity information will be entered into the system in advance and tickets with electronic tags will be generated. Similar tickets will also be issued for concerts, air tickets, etc. One reason is to prevent the occurrence of fake tickets and avoid unknown personnel entering, which poses a threat to the safety of personnel in the venue and on the plane. The second is to use
RFID contactless batch reading, which allows personnel to quickly pass through. Luggage management is achieved by attaching
RFID electronic tags to luggage during check-in and enabling real-time tracking from the security checkpoint to the destination, reducing the risk of luggage loss and misplacement.
The above are the main functions of
RFID readers. With the continuous development of the Internet of Things, the application fields of
RFID technology are becoming more and more extensive. In the future, there will be more
RFID applications worth looking forward to.
