Why?
Why am I doing this? Because I can, and it's fun to build things. Maybe someone will find this useful, one day. Maybe i'll add new features that will make it more useful.
About Barcodes
The EAN-13 barcodes are used worldwide for marking retail goods. The symbol encodes 13 numerals:
- The first two or three are a system code, usually identifying the country in which the manufacturer is registered (not necessarily where the product is actually made). This can be replaced with 978 or 979 for ISBNs, or 977 for ISSNs.
- The country code is followed by 9 or 10 data digits (depending on the length of the country code)
- For ISBN barcodes, this consists of the publisher and the item number
- It ends by a single digit checksum computed modulo 10, where the weights in the checksum calculation alternate 1 and 3. In particular, since the weights are relatively prime to 10 the EAN system will detect all single digit errors. But since the difference of consecutive weights is even, the EAN system does not detect all adjacent transposition errors.
