This scenario could come to fruition with radio frequency identification, already used by some retailers for inventory control. One employee is able to wave a handheld device, reading the RFID tags on thousands of products and updating the inventory in a few minutes. Or fixed readers located on either side of a dock door can do the same job.
RFID is a form of auto-identification, like a bar code or a quick response code. An RFID tag contains a unique serial number, like a license tag. If you go to a department store and hold a package of underwear up to the light, you can see the tag.
