A fairly broad range of pin-keypad readers as often used in healthcare have sprung to live. Would be nice if you could
also apply patch below.
The gist of this change is that it will revert PIN entry to the keypad of the reader if such is available/mandatory.
Thanks,
Dw.
* Allow for PIN/password entry on the keypad of the chipcard reader.
