What is the working range of the high-frequency reader?

　　RFID technology, also known as radio frequency identification technology, is composed of antennas, readers, electronic tags and application systems. The working range of the reader is one of the reasons that affect the working range of the RFID system.

　　High frequency reader

　　The working range of the reader is affected by factors such as the power of the reader, antenna gain, tag size sensitivity, test environment and other factors, among which the power of the reader is the most important factor.

　　According to the power of readers, high-frequency readers are divided into high-frequency micro-power readers, high-frequency medium-power readers, and high-frequency high-power readers.

　　Reader

　　The working range of the high-frequency micro-power reader is 0-20cm. It has single-protocol and multi-protocol functions, can detect IC cards in close proximity, supports ISO15693, ISO14443A, ISO18000-3M3 standards, and reads electronic tags of multiple protocols at the same time. It is widely used in desktop card issuance, access control systems, Multiple fields such as electronic bills and ticketing.

　　High frequency reader

　　The working range of the high frequency medium power reader is 65cm. It has high-sensitivity reading and writing performance and fast anti-collision processing algorithm. It performs data reading and writing operations on ISO15693 and ISO18000-3M1 standard electronic tags, realizing fast reading and writing processing of electronic tags, and has been successfully applied to drug traceability management, Libraries, logistics and warehousing, file management, production automation, laundry automation and other fields.

　　Reader

　　The working range of the high-frequency and high-power reader is about 90cm. It combines a fast anti-collision algorithm, can read more than 300 tags at a time, and is suitable for areas with high performance requirements, such as electronic dinner plates, smart bookshelves, personnel identification, jewelry inventory and other fields.
