1. A system comprising:
a structure configured to hold a plurality of items;
at least one capacitive sensor; and
an item scanner configured to generate a sensor signal when the item scanner scans the items, wherein the sensor signal is generated in response to relative movement between the at least one capacitive sensor and identification elements disposed on the items held by the structure, each identification element representing a multi-digit code, wherein the capacitive sensor touches the identification elements during the relative movement, and further wherein the item scanner is further configured to scan the items in response to a trigger comprising a signal from a sensor that senses that an item has been removed from the structure or placed in the structure;
wherein the sensor signal generated by the item scanner when the item scanner scans the items comprises sequences of waveforms, each sequence of waveforms includes the multi-digit code that identifies one of the items.
