MCAS provides powerful access control for magnetic stripe card-readers and barcode scanners. For home, office, and industrial use, the software manages up to 32 reader devices, all networked on a single serial communications cable. The MCAS database maintains up to 1000 users who may be added, modified, or removed at any time. Set configurable parameters such as reader type, door/gate activation method, open time-delay, etc. Free Visual C++ source code is included (the DLL is shareware and requires registration). Reader controllers are available at the publisher's website.
