2.4 The Enroll card and the Erase card

The Enroll card is used for switching the reader from Access mode to Enroll mode.

The enroll card can be used to write one or two fingerprint scan templates in a

card.

When storing fingerprint templates, the reader checks to see if there is already a

template on the card. If the ISO 14443 card has no templates, the template is

written on the card. If there is one or two templates on the card, the first

template is erased and the new template written instead.

o 0 templates on card => write first template to card.

o 1 template on card => writes second template on the card.

o 2 templates on card => erase first template and write new.

The Erase Card erases all the templates from an ISO 14443 card. All used sectors

with template data are erased. The AID’s of the SmartTOUCH

Xtreme application

are erased but other AID’s remain intact.

2.4.1 Activating an Enroll card and an Erase card

Two security mechanisms are used to ensure that Enroll and Erase cards only

work on those readers, which are desired.

1. Enroll code: Each SmartTOUCH

Xtreme reader contains a four byte Enroll

code. Only Enroll card/ Erase card that contains the exact same code are

accepted

When a SmartTOUCH

Xtreme reader reads an Enroll card/ Erase card,

these codes are compared. If the codes do not match, the Enroll card/

Erase card will not function on the reader.

2. Enroll card Version: Each SmartTOUCH

Xtreme unit contains a one byte

version number. Only the Enroll card/ Erase card with the same or a higher

Enroll card version are accepted. When the SmartTOUCH

Xtreme reader

reads an Enroll card/ Erase card, the version number is compared. If the

version number on the card is not greater or equal to that in the reader,

the card will not work. This mechanism makes it possible to disable older

versions of an Enroll card/ Erase card when a card is lost.

The user must ensure that the two parameters in the reader are correct. This is

done by using the Config card. If Integrated Engineering programs the Enroll

cards, each SmartTOUCH

Xtreme reader will be shipped with a Config card with

a unique value for the Enroll code.

2.4.2 Programming an Enroll card/Erase card

Both the Enroll card and Erase card are supplied with the SmartTOUCH

Xtreme

reader.
