Shopping system comprising product item and reading device

This invention describes a shopping system where physical products have special coded patterns printed on their surfaces. A user interacts with these products using a handheld pen-like device that reads the coded patterns upon contact. This device then identifies the product and its specific location on the item.

Why it matters: Filed when miniaturized optical sensors and embedded processing for real-time decoding were more expensive. Today, advancements in compact, low-power image sensors and processors make such a handheld device significantly more feasible and cost-effective to produce.
