RFID cards

UHF Antenne

UHF and wide-range

Plastic cards with UHF data transmission are on the rise in Europe. What is the key difference from HF transmission? The ultra-high transmission frequency allows ranges of 4 to 6 m with the right readers, and thus opens the door to a number of new application possibilities. In the area of logistics or tickets, objects or people can be recorded even when passing through large gates and entrances. Parking and access solutions and toll collection are possible areas of application. In hospitals, the contactless opening of doors over large distances may significantly simplify the handling of trolleys and beds.

Advantages and disadvantages

UHF cards work at a frequency of 865 to 868 MHz in Europe, 902 to 915 MHz in America, and 910 to 956 MHz in Asia. Active media, i.e. tags with batteries, work at 2.44 GHz. The consequences are fast data transmission and propagation characteristics similar to light. Obstacles in the path of the beam may significantly impair reception. The detection of people and objects always requires a line of sight between the tag and the antenna. Plasticard-ZFT will help you with the selection and the evaluation of new applications.

What is possible?

Like conventional RFID or chip cards, UHF cards are equipped with all the features provided on the right. UHF cards can also be used in vehicles as HT Card 85. Plasticard-ZFT manufactures UHF cards with the chip types U-CODE, MONZA or HIGGS. A combination with other RFID chips or contact-based data media is possible. You can find an overview of all the available UHF chips here.
