Our hands-free, long-range access control solution has given wheelchair users at a College the same freedom of movement as non-wheelchair users. The access cards are attached to the student's wheelchair and have a typical reading range of 4 metres, allowing the door to open ahead of their arrival at the door. The cards are passive so there are no batteries to change or re-charge. There are various other applications that this solution can be used for including trolley beds in hospitals and vehicle access control.
