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.
