PC/SC-lite is a middleware to access a smart card using SCard API (PC/SC) Its purpose is to provide a Windows(R) SCard interface in a very small form factor for communicating to smart cards and readers. Compiling with "DEBUGATR=1 ./pcsc-lite.SlackBuild" enables ATR parsing debug output messages. pcsc-lite no longer uses (deprecated) libhal for smart-card reader's detection. By default libudev is used now. Please see README.SLACKWARE in pcsc-lite's documentation directory for notes.
