2.5 Requirements for ISO 14443 Cards
The SmartTOUCH
TM
Xtreme writes one or two fingerscan templates in an ISO
14443 card. One fingerscan template requires approx 750 bytes storage space on
a card. Blank cards can be used, but also cards that already contain data.
Currently SmartTOUCH
TM
Extreme supports Mifare 4k and DESFire cards.
Mifare 1k cards provide unsufficient storages space.
Mifare 4k cards:
The SmartTOUCH
TM
Xtreme can be configured in two ways to store fingerscan
templates(s) in a Mifare card:
o Allocation via the MAD: The SmartTOUCH
TM
Xtreme reader will use the
MAD to allocate the required free space to store the fingerscan
template(s). This is the default configuration.
o Allocation via fixed sectors: The SmartTOUCH
TM
Xtreme will store a
fingerscan template in fixed locations. With this configuration it is possible
to register the fingerscan template in the MAD structure or to omit the
registration in the MAD.
If Mifare 4k cards with data are used, the following requirements must be met:
o If the reader is configured to use the MAD: the MAD structure must be
present and the reader must know the write access key of the MAD.
o The card must have sufficient free space to store the template (one
template takes approx 750 bytes).
o Each used sector must be registered in the MAD or the SmartTOUCH
TM
Xtreme unit must be configured to store the template in fixed locations.
If blank Mifare 4k cards are used and the SmartTOUCH
TM
Xtreme reader is
configured to use the MAD, the reader will create the MAD structure in the card.
When the SmartTOUCH
TM
Xtreme is configured to use the MAD, ISO 14443 cards
programmed with ProxBurn, must be programmed with the MAD!!!
ISO14443-4 cards:
For ISO14443-4 cards like DESFire the following requirements must be met:
o The access conditions of the card shall allow the SmartTOUCH
TM
Xtreme
reader to create files to store the fingerscan templates.
o The access conditions of the card shall allow the SmartTOUCH
TM
Xtreme
reader to write data in the fingerscan template files if they already exist
(when using pre-personalized cards).
