Hi everyone, this is a bit off topic, but I hope you can still give me some advice about PCSC api usage (mostly on win****).
background: I'm changing some commercial code at work from a proprietory interface to standard PCSC interface and wonder how you can do some of these things... Is there a way tell the reader what PPS to use? I need three modes: NONE - only work with standard speed, ATR - try the better speeds adviced in the ATR (I can do the decoding etc.) and SPECIFIC - here are some settings, please use them. Normal cards are much faster if you use ATR, i.e. up to the speed the card announces in the atr. But I happen to known broken / badly initialized cards and the ATR announced by the card doesn't work, at least with some readers, so an option to turn PPS off is very important. And then there are cards with a very cautious ATR setting (9600 / standard speed), and communication can be much faster (at least in the readers I tested them), so having the option to tell the reader "please try PPS with these settings" is a good way to speedup the communication. well - these are my results from practice in a company doing card personalisation - but so far only with proprietory card reader interfaces. Google found some old emails about this topic, but I'm not exactly sure what the situation these days is. I fear it will depend on the vendor or driver, but maybe there is a standard for this these days?
