AppIdValueType
The tag <AppIdValueType> is used when:
Mifare Desfire is added as a custom card in the tag <CCCard> and
The value of the AppId in Mifare Desfire card is a hex value.
Example:
<Config>
<CCCards>
<MFDesfire>
.
.
</MFDesfire>
</CCCards>
<AppIdValueType>HEX</AppIdValueType>
</Config>
In case Mifare Desfire is not added as a Custom card or its value is not in Hex, then the tag <AppIdValueType> is not required to be added.
