The Application can and should provide more barriers:
Sector access conditions. It is possible to assign access conditions in a way that only
decrementing of values is allowed with the keys used in the field. So even a
manipulated field station cannot be used to increment the value on the cards. As a
general rule, key A is used as a field key, allowing only to read and decrement values,
and key B is used to format the card or increment values.

Diversified keys. To make life even harder for attackers, keys can be modified using
the serial number and memory content of the card. So each card uses different keys
and a listening attack on the reader interface would be hopeless.
