This label is an RFID label tag encapsulated with a special material, which technically solves the problem that ordinary anti-metal labels cannot be attached to irregular or curved metal. Attaching the anti-metal RFID tag to the metal has great reading performance, which is farther than the reading distance on non-metal objects. Comply with EPC C1G2 (ISO 18000-6C) standard, and can print by rfid printers and write codes.
