Article from the serie "CCID descriptor statistics"
The features field is NOT a value from the CCID USB descriptor. It is a field I added to indicate special features of some readers.
Some features can be extracted from the USB descriptor like PIN Verification, PIN Modification, ICCD, number of slot. But the other features are added manually.
A majority of readers have no special feature. It is not directly visible from the table above because some readers have 2 or more features at the same time. For example all readers with PIN modification can also do PIN verification. But the reverse is not true. 3 readers can do PIN verification but not PIN modification.
If you want to find readers with a special feature, like contactless, I recommend to sort the reader matrix by 'features' field. It is then easy to find the readers with the feature you are looking for.

This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
