Fun idea, I like this one. Very creative. Are there different kinds of barcodes?

Thank you very much. Yes, while UPC barcodes are probably the most popular in places like the United States, there are other types of barcodes out there. For example, books most frequently have ISBN barcodes, which are made up of more numbers and some specialty stores, like Trader Joe's, have their own specialty barcode formats, which have fewer numbers.
