A device identifier is scanned with a portable scanner and communicated to a service provider. The service provider associates the device with the portable scanner. Information is scanned from a printed source and communicated to the service provider and subsequent information is received in response at a device identified by the device identifier. In some embodiments, a communication session identifier is scanned with a portable scanner and communicated to the service provider rather than (or in cooperation with) the device identifier.
