Re: [Opensc-devel] Typical smartcard response times

[Peter P. <pop...@gm...>]

Hi,

Response time depends on card/reader, communication speed (card-reader) is
not really important .... example for two readers, two cards:

Readers used for tests:

This reader run at 4.8MHz
$ opensc-tool -l
# Detected readers (pcsc)
Nr.  Card  Features  Name
0    Yes             Gemalto PC Twin Reader (031048A2) 00 00

This reader run at 3.7MHz
$ opensc-tool -l
# Detected readers (pcsc)
Nr.  Card  Features  Name
0    No              Alcor Micro AU9560 00 00

It can be expected that gemalto reader will be faster than alcor ..  (in
ratio 4.8:3.7)  but please check results below....
