Shelf Label

Shelf Label

【Product profile】

Shelf labels are divided into three types: high-frequency, ultra-high frequency, and QR code labels. They are the core of intelligent libraries, using reading and writing devices, equipped with software management systems and large databases, to achieve self-service borrowing, inventory, shelving, retrieval, and other functions.

【Features】

  • There is a memory, and the data stored in it can be read and written repeatedly.

  • Can be read and written in a non-contact manner.

  • Made using laser engraving technology to prevent wear and tear caused by prolonged use.

  • To prevent reading of nearby layer labels during inventory, the maximum reading distance can be controlled as needed.
