A barcode scanner is a device that is used to read the printed barcodes. A barcode consists of a series of parallel, adjacent bars and spaces that are decoded with the intensity of the light reflected by them. When the scanning is initialized, the scanner lens reads the entire code with the help of the light source and converts the code into 0s and 1s.
The barcodes generated scan well for the data that is in a particular cell. However, Iâm trying to create barcodes with Excel data and add in the function. If I simply add â~009â to the excel cell, the barcode will encode these as human readable characters and not the key.
