What counts as a 2D barcode?
Any barcode that stores data in a grid of squares rather than a line of bars. QR codes are by far the most common, used on packaging, signage, payments and marketing, followed by Data Matrix, which is more often seen on small parts and electronics where space is too tight for even a QR code.
Do you generate Data Matrix codes?
Not yet. This site generates QR codes, which cover the large majority of 2D barcode use cases. Data Matrix uses different underlying encoding logic we haven’t built and verified, so rather than guess, we’re not offering it until we have.
