Q
What is a UPC barcode?
A
You are probably familiar with the barcodes you see on most packaged products. These barcodes are in the UPC-A code format. It is 12 digits long.
Q
How does a barcode work?
A
A barcode essentially is a way to encode information in a visual pattern that a machine can read. The combination of black and white bars (elements) represents different text characters which follows a set algorithm for that barcode type. If you change the sequence of elements you get different text.
Q
How many characters can fit into a barcode?
A
Depending on the specific barcode type, 1D barcodes can have from 20-25 characters while 2D codes go up to 2,000 characters. The main practical concern is that as you increase the amount of information in the barcode the bigger it will become. This is especially the case with 1D barcodes and in use most people encode 8-15 characters.
Q
How to make the qr code appear on screen?
A
Use "Display" command along with file name to show the preview of the QR code
