13. A Word About Encryption 
 
 
“Wiegand Card Data” mode takes advantage preprogrammed DES encryption.  
Each reader is loaded with a proprietary master encryption key which is used to 
decrypt the data stored in blocks 0-4 of the preprogrammed badges.  Card 
Programming software can be purchased separately, allowing the user to program 
badges using either the default master key, or a custom key.  Badges programmed 
using a custom key can be read in “Card Data” mo de so long as the custom key is 
selected and entered in the “Encryption” option under the “Configuration” menu.
