In some implementations, the client device includes one or more cameras, scanners, or photo sensor units for capturing images not shown. Optionally, the client device includes a location detection device 616, such as a GPS global positioning satellite or other geo location receiver, for determining the location of the client device. The memory 606 includes high speed random access memory, such as DRAM, SRAM, DDR SRAM, or other random access solid state memory devices; and, optionally, includes non volatile memory, such as one or more magnetic disk storage devices, one or more optical disk storage devices, one or more flash memory devices, or one or more other non volatile solid state storage devices. The memory 606, optionally, includes one or more storage devices remotely located from one or more processing units 602. The memory 606, or alternatively the non volatile memory within the memory 606, includes a non transitory computer readable storage medium.
