This is useful when diagnosing issues related to a card that is supported by Symantec Encryption Desktop which is no longer working. Sometimes manufacturers produce newer revisions of a model with a newer ATR code. This may be requested by Symantec Technical Support to diagnose problems with Smart Cards and Symantec Encryption Desktop (formerly PGP Desktop).
Symantec Corporation recommends the first course of action is to contact the manufacturer of your smart card. Most Smart Card manufacturers have a way to obtain the ATR codes using their software client or can tell you the ATR code based on other information about the device.
This How To requires you to install a utility to obtain the ATR codes by downloading this software. If you are not comfortable doing this, we would strongly suggest you contact your manufacturer for assistance.
