Claim 2:
2. A method according to claim 1 , wherein: said first barcode is readable before exceedance of said at least one threshold, said second barcode is unreadable before exceedance of said at least one threshold, and upon exceedance of said at least one threshold said first barcode becomes unreadable as a result of coloring of at least a portion of said at least one first colorable area and generally simultaneously said at least a second barcode becomes readable as a result of coloring of at least a portion of said at least a second colorable area.
