Can RFID tags work when they are attached to metal surfaces or embedded within metal products?
RFID tags are the small devices that can be embedded in labels or attached to tags which work with radio transmitters and/or receivers to identify themselves.
RFID tags can be used to do the following:
- Track individual items
- Track boxes of products, cages of products and pallets
- Track containers with multiple loads
- Locate equipment within a building
- Trigger alarms should equipment or stock be removed without authorisation.
RFID devices have a very small integrated circuit incorporating a small memory capability - many are smaller than 2mm square and 2mm thick. Despite its size, many can hold 2000 characters of data.
RFID operating rage depends on the radio frequency used, receiver capability and the environment. Some tags are only readable from under 1m, others can have a 100m range.
RFID tags and labels are very specific to the type of material and size of your assets. For example, metal will deactivate the RFID antenna and the tag will not transmit at all. Using RFID on metal requires a special type of tag with an RFID block to prevent interference with the antenna. Liquid products can also affect the reliability of the RFID signal. To use RFID tags in specific environ-ments, some technologies are needed to support them.
