Blackboard MRD5 User Manual
The Blackboard model MRD5, is a Mobile Reader Device for reading Blackboard mag-stripe and
contactless cards. A card-swipe allows reading of mag-stripe cards and an internal antenna
provides the capability to read Near-Field Communication (NFC) credentials. It operates as a
peripheral device to a host such as a smart phone or tablet with communication being provided
over USB or Bluetooth Low Energy (BLE). When a Blackboard credential is read, the information
on the credential is then transferred to the host device. Application software must be
installed on the host device to work with the MRD5.
The MRD5 has a card-swipe for reading mag-stripe cards. An internal antenna provides NearField Communication (NFC) to allow reading contactless cards and NFC type credentials. A
switch controls when the device is powered on or off, and a chargeable Lithium-Ion battery
provides up to 40 hours of continuous operation.
