Using Smart Cards
The Prox–DU and Prox–SU reader/writers must be used with contactless and contact smart
cards. Depending on the model, the following pictures show the different ways to use the
smart cards:
The Prox–DU and a contactless smart card:
Figure 6 – The contactless smart card is put near or over the Prox–DU landing zone
Figure 7 – The contactless smart card is not fully inserted into the Prox–DU slot
Note: if the contactless smart card is fully inserted into the slot, the contactless interface will
be deactivated because the contact interface has a higher priority than the contactless
interface.
