Maybe by having every barcode begin and end with the same 'prefix' and 'suffix' sequence (prefix <> suffix)? It takes more bits, but if you manage to read the prefix and the suffix correctly (as you know what they should be) you could be relatively confident that the message portion in the middle also was correctly read. -- Anders Isaksson, Sweden BlockCAD: http://web.telia.com/~u16122508/proglego.htm Gallery: http://web.telia.com/~u16122508/gallery/index.htm
