This is a low cost bar code reader made from a product which has a very long history. You can see it at this link. The bar code reader named CueCat is built to be connected in a PS2 keyboard port (standard PC/AT Keyboard). The problem is the information encrypted.
I decided to build a small interface which fits in the CueCat to convert, decode the information and send it via RS232. Each time you scan a product, the decoded code is sent serially and is stored in an EEPROM which could store up to 128 bar codes. The idea is to read many bar codes away from the PC. This information could be retrieved later when the bar code reader will be connected to your PC. Later, you could send some commands to communicate with the CueCat. For example, "G" will get all the codes currently stored in the EEPROM; "C" will clear the entire memory.
- Very low cost
- 128 bar codes memory
