Specially designed for tubular objects such as utility poles, lamp posts, cables, etc., the back is curved and tied with zip ties for fixation. It is resistant to high temperatures, wear, corrosion, and water, and the supply of data and electrical energy is transmitted in a non-contact manner (without battery power supply). The working frequency is 13.56 MHz (industrial safety, allowed for free use worldwide), and the communication protocol is ISO15693. It is truly conflict resistant and allows multiple tags to be read simultaneously. It has a data retention capability of over 40 years, and each chip has an unchangeable unique identifier (serial number), ensuring the uniqueness of each tag.
