Abstract

A two-dimensional bar code is used to identify a traveler'"'"'s luggage, permitting the luggage to be tracked and, if desired be delivered to the traveler'"'"'s ultimate destination (e.g., a hotel). If the traveler is traveling on an airline, a corresponding two-dimensional bar code is applied to the traveler'"'"'s boarding pass. A two-dimensional bar code reader is used to read the boarding-pass bar code of each enplaning passenger; comparison of these bar codes with luggage bar-code data permits an alarm to be raised if each item of checked luggage is not matched by an enplaned passenger. The boarding-pass bar code may take the form of an integrated passenger identification code for use by e.g., rental car companies, hotels, and the like.
