RFID anti-metal bookshelf tags are usually pasted on the bookshelf. This allows them to manage books on the same shelf and avoid the influence of metal shelves on labels.
RFID shelf labels are mainly made of PCB or ABS materials. They have an anti-metal antenna design. You can also attach a layer of acrylic or glue to the surface to make them look more beautiful. The RFID chips used are usually high frequency or ultra-high frequency. You can choose freely. You can also customize the size, color, and craft.
