There are lots of sites on the Internet that offer barcode tags of any
size, color, configuration, etc. that you might want.  I went to Google and
typed in bar code tags.

The bar code folks will sell you preprinted tags and labels or blank tags
and labels on paper, plastic, aluminum, ceramic, etc.  Many have a form
that you fill out and submit.  You list size, material, what you wanted
printed, etc.

The catch is that the price goes way down as the size of the order goes up.
 So, the message is that one of the bee supply firms or a group of
beekeepers should go together on an order.
