Abstract
A commodity key for use in connection with radiation sensitive encoding devices provides a unique pattern of radiation identifying the type and/or unit price of a commodity in a computing scale. The key has an elongated body (10) with a code area (20) formed of a frangible plastic material opaque to the radiation used in the encoding device. The code area has a first plurality of insets or blind holes (21) in one side thereof, and a complementary second plurality of insets or blind holes (25) in the opposite side. The sets of insets are individually adjacent and aligned to define potential radiation transmissive openings through the code area, and the insets in one set are somewhat larger than the insets in the other set. The material (27) dividing adjacent insets thus is readily frangible in response to pressure exerted thereon through the smaller of the adjacent insets to form effective radiation transmissive openings, thereby facilitating on-site encoding of a key.
