Abstract
An apparatus and method for detecting and indicating unknown data associated with a selected article having a unique identification code employs a plurality of stored data tones. The data tones are stored in numeric order, each tone having a frequency corresponding to the data associated with an article having an article identification code corresponding to the sequential number of the data tone. The data tones are temporarily stored and counted up to the number of the selected article identification code whereupon the frequency of the corresponding data tone is displayed.
