In smart healthcare, RFID technology provides efficient and accurate information storage and testing methods for medical monitoring. In the emergency department, due to the large number of patients, traditional manual registration methods are inefficient and prone to errors. To this end, RFID wristband labels are worn for each patient, and medical staff only need to scan to quickly obtain patient information, ensuring that emergency work is carried out in an orderly manner and avoiding medical accidents caused by information input errors. In addition, RFID technology can also be used for automatic identification and tracking of medical devices and drugs, further improving medical management and security.
