Sewable RFID tags for clothing use RFID technology, by sewing or stamping on the fabric, tracking and recording the entire fabric use process, including the use status, the number of washings and washing management. It makes the handover of washing tasks simple and transparent, and reduces business disputes. At the same time, by tracking the number of washing times, it can provide users with an estimate of the current service life of the fabric, and provide predictive data for purchasing plans.
