In the state of Texas, a tax stamp must be applied to each liquor bottle sold at the wholesale level. Goody Goody Liquor, whose wholesale division services more than 600 hotels and restaurants in the Dallas area, wanted to automate the process of reading the stamps to ensure each bottle has a tax stamp and the data is accurately stored in a database. Using a versatile bar code reader, the company has improved accuracy in variable conditions. Working with an integrator (Cisco-Eagle, cisco-eagle.com), Goody Goody developed a system that automatically applies the tax stamps with 1D bar codes and reads the bar code for verification and tracking. The system processes one bottle per second, but the bottles have different shapes and backgrounds, and the label position varies. Lighting also continually changes, further challenging the readers.
