Abstract

An exemplary method involves reading a first identification tag. The first identification tag includes an instruction to form a logical connection with a computing device. Address information associated with the computing device is used to form the logical connection with the computing device in accordance with the instruction. Data is obtained. The data is transmitted to the computing device via the logical connection.
