General Information Contact Methods
Landing Contacts
With this contact method a moveable contact set will connect
with the pads of the chip card upon insertion of the card.
The card plastic surface is not scratched and highmating
cycles can be achieved.
Wiping Contacts
The contact set is xed. When the card is inserted, it wipes
over the data contacts until they arrive at the card pads.
Depending upon the card surface, wiping traces which do not
inuence the card function can occur after some insertion
cycles.
The advantage of wiping contacts is that they clean the
contact point with every mating cycle.
