Semacode | URL barcodes | practical ubiquitous computing: How it works

Semacode tags such as the one at left are based on the international ISO/IEC standard Data Matrix. A semacode tag uses this type of optical 2D barcode to store a URL in a secure format that can resist up to 50% damage to the tag.

Application developers and general users can create their own semacode tags using the Tagger tools. It's a simple matter of typing in a valid URL and then posting the barcode wherever you like. Anyone is free to create as many different semacode tags as they like.

When you have semacode tags to read, the solution is the semacode Reader tools. The reader tool is available in many forms to suit the needs of different audiences. For example, there is Reader software for common Java Phones, smartphones, and also for PCs and internet servers. The Reader takes advantage of the camera that is found in most contemporary mobile phones.
