GoMo News are running a poll, QR Code vs DataMatrix – Do you know the difference? Currently it is showing that their readers are finding it difficult to distinguish between the two. This is hardly surprising as GoMo recently published an article claiming that Marks & Spencer are using QR Codes, M&S uses QR Codes for on-packaging mobile barcode trial, when in fact they are using Datamatrix codes. GoMo even illustrated the article with a QR Code! I guess, you are what you read.
