The ISO Card is a battery-free UHF read only card, suitable for long- range applications. The ISO Card is particularly suitable when a single card should be used for different vehicles, or when the card should also be used together with an access control system for people identification. The ISO Card can be read from both sides, and has a printable front and pre-printed identification at the back of the card to allow easy issuing to users. The cards are delivered in continuous running number series.
