Abstract
A system for storing and retrieving data comprises a memory device, such as a radio frequency tag, having a memory for storing the data, a first identifier stored in the memory, and a machine-readable symbol associated with the memory device. At least a portion of the machine-readable symbol encodes a second identifier logically associable with the first identifier. The machine-readable symbol may be printed on an RF tag, or may be carried by a container that also carries an RF tag. The machine-readable symbol is composed of characters from a machine-readable symbology, and includes a flag character that indicates the existence of a memory device corresponding to the machine-readable symbol. A reader for reading the machine-readable symbol and the memory device conserves power by determining from the flag character whether a memory device is associated with the symbol, prior to operating a memory device reader section of the reader. The reader reads the machine-readable symbol to obtain a symbol identifier, and successively reads each of a number of memory devices to obtain a memory device identifier until a memory device identifier corresponding to the symbol identifier is found. Alternatively, the reader may successively read each of the number of memory devices to obtain each of the memory device identifiers, read the machine-readable symbol to obtain a symbol identifier, and match the symbol identifier to one of the memory device identifiers.
