I'm not convinced that code128 won't hold what we need, since all we need is a unique alphanumeric code. I'm still checking on that. And I will not put symbology face up, nor will any entomologist I know accept that. >Furthermore, the new "imager" technology is far superior than than the old >laser scanners that we are now using.

Tell me more. Is this getting close to optical character recognition, where we won't need a symbology at all? Then I might accept a face-up label, that has all the locality data and a unique number. Any ideas on who might maintain a registry of barcode labels being used? Jack ****************************************************** John T.
