GIF or PNG Products BarCodes

[Jacques Le Roux]

Thanks for explanation Andrew,

Yes nowadays things change so quickly ! 2 years ago I was wondering to use a PDA with a scanner extension for such uses (cheaper
than an inventory handheld).
I did not try because of my client but this is also a possibility and now with the Hhfacility component it takes more sense.

Remember 1st USB keys, they spread very fast after and are sold by Millions for some bucks now...
