RFID Tags for every business need

There is a wide range of RFID Tags available for different applications. RFID 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.

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.
