In order to profit from the full functionality of the HITAG VEGAS data carrier, the read/write 
device has to support the data carrier´s cryptographic feature. 
 
This requires the use of some secret data (keys, logdata). The process of  loading these data into 
the  HITAG VEGAS read/write device is called personalization. The analogous 
personalization procedure has to be carried out on your data carrier. The read/write device and 
the data carriers are prepersonalized by Philips by means of defined Transport Keys and 
Transport Logdata. Therefore you can use the HITAG VEGAS read/write device without 
changing any data. Because of security considerations we recommend to use own keys and 
logdata. So only persons who got the authorization from you are able to access the secret area of 
the data carrier. To use own keys and logdata you have to personalize read/write device and data 
carrier. This process is described in the following chapters. 
 
Make sure you are in safe environment while writing these secret data to the data carrier or the 
HITAG VEGAS read/write device. This prevents possible listening into the communication 
between HOST and read/write device.
