Claims
- 1. An apparatus comprising:
- a time-varying nonpredictable code generator;
- a scrolling display device responsive to the time-varying nonpredictable code generator to display a time-varying nonpredictable bar code wherein the bar code scrolling display displays a first bar code at a first time and a second bar code at a second time, the second bar code having a bar removed from an end of the first bar code;
- a housing to support the time-varying nonpredictable code generator, the housing having an inset portion at which the display device is accessible.
- 2. The apparatus of claim 1 wherein the time-varying nonpredictable code generator is synchronized to a second code generator.
- 3. The apparatus of claim 1 wherein the bar code scrolling display includes a liquid crystal display.
- 4. The apparatus of claim 1 wherein the pulsed signal corresponds to a bar code selected from the group consisting of a 3 of 9 bar code, a UPC bar code, a Code 128 bar code, a Codabar bar code, an MSI bar code, an Extended 3 of 9 bar code, a Code 93 bar code, an Extended Code 93 bar code, an Industrial 2 of 5 bar code, a Standard 2 of 5 bar code, a Code 11 bar code, a UCC bar code, and an EAN/JAN bar code.
- 5. The apparatus of claim 1 wherein the pulsed signal includes a pulse-width modulated signal.
- 6. The apparatus of claim 1 wherein the bar code scrolling display displays the second bar code to have at least one bar of the first bar code shifted in a direction.
