What is 1D/2D 3D barcode?
There are two general classes of barcodes: one-dimensional (1D or linear) and two-dimensional (2D). The difference between 1D and 2D barcode scanning relies on the layout and amount of data that can be stored in each, but both can be used effectively in a variety of automatic identification applications.
What is difference between Pharmacode and barcode?
pharmacode is technically not really a barcode, at least not as we think of barcodes. While it does encode numerical data sort of like a UPC does, it does not have a start stop pattern, and thus pharmacode is meant to be scanned in one direction only.
What is a 1D barcode?
Q: WHAT IS A 1D BARCODE? A: A 1D barcode (also known as a linear code) is a visual black and white pattern, using variable-width lines and spaces for encoding information.
How can QR code be used for augmented reality?
