When RFID tags are thought of, adhesion is thought of because specialized, permanent pressure sensitive adhesives RFID tags are used prolifically to attach adhesive-backed tags to assets. Some adhesives will withstand a great deal of pull pressure even in extreme environments, while others will release more easily. The pull strength selected will depend upon the intended use of the asset and its potential lifespan. Some adhesives are applied to tamper-evident tags to leave an unremovable adhesive imprint if the tag is removed.
RFID tags are attached to assets in other ways too. Many hard tags, especially those used with active RFID tags, are attached with metal fasteners such as screws. Button tags used in laundry venues as well as others places can be glued, but also sewn,heat-sealed or tied. Die cut tags with circular holes allow hang tags to dangle from lanyards, cords, cables, and zip ties. Popular fob tags swing from key chains. Die cut RFID hang tags can also be cut to form a hang hook in the tag itself, thus enabling the tag to hang itself.
