2Dmerkintöjen
2Dmerkintöjen is a Finnish term that translates to "2D markings" or "2D codes." It refers to a type of data carrier that stores information visually, typically in a two-dimensional matrix of black and white squares or dots. Unlike traditional one-dimensional barcodes, which store data linearly, 2D merkintöjen can encode a much larger amount of information in a smaller space.
Common examples of 2D merkintöjen include QR codes and Data Matrix codes. QR codes, for Quick Response
The information encoded in 2D merkintöjen can be read quickly and accurately by imaging devices like smartphones
