Even though the CueCat uses a
modified method of BASE64 it is possible to use a simple reference
chart to decode numeric barcodes only. To start off I will
give some example data and then take you through step by step of the
process of using the chart.
First step scan a barcode using your CueCat. Remember that for you to get the data you MUST uninstall the CueCat software (or not install it to start with). You can then start a simple text editor such as Notepad. To run Notepad click Run from the Start menu and type in Notepad and press enter. This will then start the program. Once you scan in data it should look something like this: So let's decode this barcode. The data of the barcode are held in the last segment of data. The data that we will decode is: Dhf2Cxr3E3bYDNT1C3a Every three digits in the barcode are encoded in four digits of the data from the CueCat. So we must first start with the first four digits "Dhf2" this will tell us the first three numbers of the barcode. Second, we need to take the first two characters of this four character set and find it on the reference chart in the 1st and 2nd character column. This gives us: 7 Third, we need to take the third digit "f" and find it in the chart under 3rd letter. Thus our second number is: 2 Forth, we need to take the forth digit "2" and find it in the chart under 4th letter. Thus our third number is: 5 Fifth, you will go on to the next set of four digits and start at step two again, until you complete the output data. The final number is: 72527483158603 I would recommend going on to the more detailed part in the Full Decoding page. |
