RFID Tags


Tags for every business need

There is a wide range of RFID tags available for different applications. Tags can be passive, active or battery assisted passive. They can be read only or read/write. The business need and the environment they will be used in will dictate which tags are best suited for each client.

You can see some of our wide range on the RFID tag pages of our on-line shop.

Different types of tags have different data capacities. Typically tags have 224 bits to circa 1k bits of user memory for LF tags, 2k bits for HF tags, 64k bits for UHF tags.

The relatively low capacity of data that can be held on tags means that applications need to be carefully designed and generally involve linking data held on the tag with data held on an external database.

Tags can be read only (supplied with pre-coded identity data only) or writable, allowing for limited updating of information on the tag.

Different tags have the ability to cope with different physical environments, shock and vibration, exposure to magnetic fields, moisture and chemicals and so on. The size of different tags will also determine antenna size and performance. The size (and in some cases the orientation) of the tag’s antenna can affect read ranges, read response times and read reliability rates. As a result it is important to consider the performance of the tag in a particular application before selecting the tags to be used.

Applications requiring writing to the tags need to be carefully designed since write performance is relatively slow.

Types of Tags

  • Key-ring fob tags
  • Disk tags (can be drilled for mounting using screws or bolts)
  • Wrist band mounted tags
  • Self-adhesive label tags, flat, mounted on plastic
  • Tamper-proof label tags (attempted removal makes the tag useless)
  • ‘Credit Card’ style tags
  • ‘Laundry’ tags (temperature, chemical and heat resistant)
  • Glass mounted tags usable in extreme environments with water or chemical exposure, for example.
  • Tags with a backing label for over printing.
  • Strips of roll-mounted tickets with embedded tags, designed for printing and encoding at the time of issuing.
