HF Tags

A wide range of HF Tags are available. Physical form factor and processing requirements of the HF Tag are the primary factors that help decide which tag to use. In addition, the amount, type and security level of the information which needs to be stored on the card determine the appropriate tag. TI provides HF Tags, suitable for paper and plastic lamination.
