Claims14
In apparatus including a digital memory, a sensor for sensing information from the memory, logic circuitry operatively coupled with the sensor, and a display in operative relationship with the logic circuitry for visually displaying information stored in the memory, the improvement comprising:
- a portable container containing said memory, sensor, logic circuitry and display and defining an opening for receiving said digital memory;
- and
- control means in operative relationship with said logic circuitry for enabling an operator of the apparatus to control the information displayed;
- said memory including a substantially rigid card containing a matrix of holograms and wherein said holograms contain binary bits of information.
In apparatus including a digital memory for storing readable information in digitally encoded form, a sensor for sensing information from the memory, logic circuitry operatively coupled with the sensor for decoding the digitally encoded information into readable information, and a display in operative relationship with the logic circuitry for visually displaying the readable information, the improvement comprising:
- a portable container containing said memory, sensor, logic circuitry and display and defining an opening for receiving said digital memory;
- and
- control means in operative relationship with said logic circuitry for enabling an operator of the apparatus to control the information displayed.
