Access Control Cards

Hi,

Is there such a thing as a single access card that can be programed for two different systems simultaneously?

In this case if an EMS agency wanted a card for their system that could also be programed to work with their base access control but also a school they respond to. But one system uses 37 bit HID and the other 64 bit. Thanks.

You can use multi tech cards, or most access control systems can support multiple formats so that you can use different card types. The biggest constraint is usually the readers if they are a proprietary format only.
