Each card swipe is separated by a newline character when read in from the cardscanner file. The file is always nonblocking and so a read called on the file when there is no information available will return 0. It creates a file in /dev called cardscanner which can be read to get this information. This device driver manages a MagTek USB card reader and allows userspace program to easily get swiped card info. This will compile the module, create a file on modprobe.d so that usbhid ignores the card swipe device, reloads usbhid, and inserts cardscanner. of China Hungary India Indonesia Ireland Israel Italy Jamaica Japan Kuwait Latvia Lithuania Luxembourg Macao S.A.R.MagTek USB Card Scanner Driver MagTek USB Card Scanner DriverĪuthors: Patrick Tully and Steven Bronson
