Microchips (also known as glass tube tags) are an important innovation in RFID technology, bringing great convenience to multiple fields. In particular, UHF RFID windshield tags are attracting widespread attention as an application form of microchips. Microchip tags typically consist of a tiny glass tube container with a chip and embedded antenna that communicate with the read-write device via radio frequency signals. This compact design allows the tags to be easily embedded in objects, independent of the environment. UHF RFID windshield tags are particularly attractive because they can be installed inside a car’s windshield, enabling vehicle identification and data capture without direct line-of-sight. Microchip (glass tube) tags bring new prospects for applying radio frequency identification technology with their small size, durability, and multi-function. Especially UHF RFID windshield tags will continue to create smarter and more efficient solutions in vehicle management and other fields.
