The chip is disposed at one end of the antenna layer. A retainer and a fixing pin are disposed at the end of the fabric layer away from the antenna for fixing to clothing. The retainer can be sewn onto the clothing, and the fixing pin is fixedly connected to the fabric layer. The retainer has an inner cavity into which the fixing pin can be inserted. The inner cavity contains a spring, a retainer, a movable frame, and a ball. The ball is disposed in the movable frame through the retainer. The movable frame can slide up and down in the inner cavity, and the retainer can slide up and down in the movable frame. The fixing pin has a slot, and when the fixing pin is inserted into the inner cavity, the ball can engage with the slot. A pressure plate is disposed at the end of the retainer away from the fixing pin. The spring is disposed between the pressure plate and the inner wall of the inner cavity. A magnet is disposed on the pressure plate.

[0007] Furthermore, a partition is provided in the inner cavity, which divides the inner cavity into a compression chamber. A spring is provided in the compression chamber. Both the partition and the movable frame are provided with sliding grooves. The edge of the pressure plate passes through the sliding grooves of the movable frame and the partition in sequence and is connected to the spring. The spring is a tension spring.

[0008] Furthermore, a printed cloth is provided on the surface of the fabric layer near the chip end, and product information, QR codes, or barcodes are printed on the printed cloth.
