Proximity cards for SMDP system authentication
SMDP or Liquid Dispensing Monitoring System is a tool that exercises control over dispensed fuel in an enterprise.
Among other things, proximity cards are used for each access to the SMDP system, acting as user identification. All fueling will be registered to a specific person or vehicle (single identification) and to a person and vehicle simultaneously (dual identification). The administrator sets access limits for each person or vehicle and can prevent real-time viewing of spent fuel.
Intuitive and easy-to-use software will significantly facilitate the supervision of fuel management.
SMDP proximity authorization cards are dedicated for automatic RFID reading. They are made of PVC (polyvinyl chloride) and are equipped with a microprocessor as an information carrier. Unlike key fobs, they only have a different outer casing, the principle of operation is the same.
Diagram of operation of proximity cards for authorization of SMDP system
SMDP proximity authentication cards transmit data via radio waves. They allow operation at a range of several centimeters to several meters from the reader antenna. An alternating electromagnetic field caused by the proximity system accumulates around the antenna. The cards do not have their own power supply - they are powered by inductive current.
Advantages of using proximity cards for SMDP authentication
Immediate user identification
Granting access/restricting user privileges
Ergonomic design - comfortable to carry and use
Damage resistance subject to skillful storage
Security of data storage
