A redeemable carbonated beverage can on the lid of which there is provided a pair of spaced, redundant, arcuately distributed code patches containing regional redemption information. The code patches are read by a scanning laser beam. These patches may be formed in several different ways, as by impressing them, embossing them, or printing them. Information in the patches may be coded in any convenient manner, as, for example, in a binary-type code or in a frequency-type code.
