Some readers provide reader-implemented ADPU firmware, that translates T=0 command/responses into the micro-instructions used by the 4422. This avoids having to support CT-API in powerful hosts with Unix/win32, or use PC/SC architectural hacks which have implementations load proprietary CT Api plugins.
The ACR 80 from ACS , for example, has firmware with 8 SAMs - one for each payment capture backend, - and can read a 4428 protected EEPROM 1kbit card.
There is no reason why the BSD unix build of PC/SC lite should not be able to interface to this peripheral (which hides the SLE 4428's nature). When I tried omincard 2020 on Linux, however, it would not install - supporting only older kernels.
--------
Could we imagine writing a special PC/SC driver that implements a limited part of the card edge protocol spec, translating the protocols PIN authentication into 4428 PIN mechanisms (via the reader support), and storing an object via a synchr. update?
That would be fun! Hmm. when I tried it on Linux, the ACS driver
would enumerate the bus for the vendor/prod ids, but failed to communicate
control packets. Wonder if the ACS drier source built on win32, so we could try
to have the ACS driver do the required emulation in support of card edge?

(fair use of the ACS copyrighted spec, for academic use):

>Another question: is there a possibility to access memory cards (SLE4442, german health card) with pcsc? There are many people waiting for a solution on Mac OS X, but there is no CT-API on OS X.
