HD Barcode

HD Barcode is a 2D bar code symbology that is claimed to support high-density data up to 703 kilobytes per bar code (exactly how big a bar code is needed for this data size is unstated). An HD Barcode appears to resemble a maze (amazing!), but in actual use is printed in a smaller size where its shape isn't as visible to the naked eye.

An intended use is for "brand protection" (a buzzword common where marketers and lawyers meet) by storing encrypted data that can be embedded on product packaging to verify that the product is authentic.
