  • Wi-Fi Card Access System (WCAS)
    RFID (proximity) reader + access controller
    Wireless card access and control!
      Also accepts optional external card-reader: magstripe or RFID


    The Wi-Fi Card Access System (WCAS) is a plug-and-play solution that consists of WC-5150 reader/controller (shown above) and Windows software (sold separately).  The WC-5150 device combines RFID (proximity) reader and access controller (for optional door/gate entry).  The WCAS is sleek and compact, measuring only 5.5" x 4.75" x 1".  This Wi-Fi solution is simple to install and requires no communications wiring.  It is ideal for use in the following applications:

    • Kiosks
    • Card logging
    • Office area access
    • Gated communities
    • Inventory tracking
    • Student identification
    • Employee attendance
    • Tradeshows & conventions
    • Security systems
    • OEM applications

    (Note:  The WC-5150 is designed for indoor use and must be appropriately shielded from the elements if used outdoors.)  The WCAS is comprised of two primary elements:

    • WC-5150 controller
    • MCAS host software

    Compatible with standard Wi-Fi networks, the WC-5150 controller is a self-contained device with wireless TCP/IP interface, integrated RFID reader, and AC adapter.

    MCAS Online
    host software for Windows is our flagship access control software for magstripe and RFID applications and is also compatible with WC-5150 controllers.  With a database capacity of 50,000 card users, MCAS online provides functions for card access, logging, enrollment, and more!  MCAS Online is available in 3 editions: lite, standard, & premium.

    For OEMs and developers interested in designing custom application software, the WC-5150 can be used with your custom developed software. 

    The WC-5150 can be used with an array of available card and tag (fob) media.  The following compatible formats are accepted:

    • EM4001
    • EM4100
    • EM4102
    • EM4200
    • HID ISOProx II

    The WC-5150 unit is easily configured for your network using any suitable USB-to-RS232 adapter (not included).  Or, if desired, we can pre-configure the unit for you.  The following network parameters are applicable:

    • SSID
    • Passphrase
    • Gateway (router) address
    • Static I.P. address
    • Port number

    The following network authentication modes are supported:

    • WEP
    • WPA
    • WPA-PSK

    Installation is a breeze.  Simply mount the controller unit on a convenient wall or other surface and plug the AC adapter into a nearby wall outlet.  Use our Windows PC host software to add card users and to drive the controller.   Click here to learn more.
