Wireless OSDP reader for MIFARE® 13.56 MHz cards
The MM-R74 is a weatherproof wireless RFID reader for MIFARE® cards. The reader communicates with the MM-D74 base module using a wireless transmission based on the energy-efficient IEEE 802.15.4 standard. The base module, in turn, works with a controller using the OSDP protocol (EN 60389-11-5).
The reader was designed to operate within the MicroMade Secure Identification System (MmSID). This allows for the creation of an access control system with the highest possible security grade, level 4. Depending on the configuration, the reader can read and transmit the following to the controller:
- Encrypted data from MmSID installation cards (MIFARE® DESFire® type cards)
- The unique identifier (UID) of MIFARE® proximity cards (in accordance with the ISO/IEC 14443A standard)
- An identifier from the MmId app on an Android smartphone
Reader configuration
Up to two MM-R74 wireless readers can be paired with a single MM-D74 base module. This set can be configured even after installation and connection to the OSDP bus. This is done using a special interface called MmSID Manager, which can search for all readers connected to the controller’s OSDP bus. It can then set the desired transmission speed, assign individual OSDP addresses required by the controller, and transmit the cryptographic keys needed to read cards for a given installation.
The MmSID Manager is operated using the MmSID Config software.
Installation
The MM-R74 reader is weatherproof and can be used both indoors and outdoors. It is a convenient, handheld device with a durable, aesthetic housing made of ABS plastic. The reader is also equipped with a rubber cover to protect the device from impacts. The reader operates with the base module at a distance of up to 100m in an open area.
The MM-D74 base module has a weatherproof, wall-mounted housing. It should be placed as close as possible to the area where the wireless reader will be used.
Application
The primary application of the MM-R74 reader is for registering and checking the access rights of employees entering a facility in a single vehicle.
