Each decoder had a pixie that reads the lines and spaces calling them out and another that translated it into good ol English ?
more complex 2D barcode format such as PDF417 or DataMatrix contains more information inside. for example the one printed on Emirates ID registration form.
XTY, do you nkow how to establish a look up relationship between your the barcode reader and the database where the information about the product is kept.
I have a barcode reader which reads a barcode and shows me the number i.e 24867920, which is the same number as the barcode of some product.
Now I want it to be able to read the barcode and then display on the screen what 24867920 mean. for example 24 could be first name, 86 could be surname, 79 could be city and 20 could be the country. so when it looks up 24 in the database it will return Ahmed in the first name field of the form and so on.
But not sure how to do this look up relationship and where it should be established. Do you know or do you think you can point out to some websites which might be able to help me out?
