A method for generating tags embedded with data, comprising the steps of:
- printing, using an encoder, a tag having a data area comprising data dots and a locator component comprising constant dots;
- using the tag encoder to obtain tag data from a tag format structure, the tag format structure being a dot based data package template containing a plurality of entries, there being an entry associated with each dot's position, an entry indicating whether a data dot or a constant dot, accordingly each entry having either fixed data bits or variable data bits.
