Abstract
An improved character reading system that utilizes two separate read devices: a first read device and a second read device in combination with a random access memory for storing each character read by the first read device, a memory control circuit for writing each character into the random access memory, and a comparison logic circuit for comparing each character as read by the second read device with the corresponding character stored in the random access memory. The system also includes a time-out counter for indicating when the last character has been read and a comparison logic timing circuit for controlling the comparison logic and triggering the random access memory read control circuit so as to provide the corresponding character to the comparison logic.
