Abstract

A data collection system useful for trade shows employs identification cards each having a semiconductor memory chip for recording and storing data relating to individual attendees. The system includes an encoder/decoder that is coupled between a keyboard and a computer. The encoder/decoder accepts the memory cards for recording the data generated at the keyboard and for reading the recorded data at a later time.

Claims

1. A data collection system for processing and storing information that is recorded electrically on an identification card having a semiconductor memory chip embedded therein comprising:

a data processor having an input terminal for receiving data;

a keyboard for generating a data signal in response to actuation by an operator;

an encoder/decoder circuit coupled to the output of said keyboard for receiving said generated data signal, said encoder/decoder circuit having an interface for coupling said circuit to said data processor input terminal;

means formed with said encoder/decoder circuit for receiving said identification card so that electrical connection is made between said memory chip and said encoder/decoder circuit.

2. A data collection system as in claim 1, wherein said encoder/decoder circuit comprises an electronic switch for controlling the flow of data signal between said data processor and said encoder/decoder.

3. A data collection system as in claim 2, wherein said electronic switch is a dynamic multipole, double throw switch.

4. A data collection system as in claim 1, wherein said encoder/decoder circuit comprises a microprocessor for encoding data received from said processor and for decoding data recorded on said card.

5. A data collection system as in claim 4, wherein said encoder/decoder circuit includes a program memory for controlling the operation of said microprocessor.

6. An encoder/decoder circuit for providing an interface between a keyboard and a computer having a keyboard connector comprising;

a microprocessor coupled to said computer for receiving data formatted by said computer and for encoding and decoding said formatted data that is stored on a memory card;

a socket for accepting said memory card coupled to said encoder/decoder circuit;

an electronic switch for directing data signals from said keyboard to said keyboard connector;

said microprocessor being connected to said electronic switch for controlling the functioning of said switch, said microprocessor being connected to said memory socket for transfer of data signals to and from said memory card; and

a program memory coupled to said microprocessor for controlling the operation of said microprocessor.
