A stock monitoring system, includes a portable device (e.g. PDA), the portable device 124 including a first processor and, coupled thereto, a first wireless transceiver for short-range communication, the portable device receiving user inputs from a first user. A second wireless transceiver is coupled to the first processor, the second wireless transceiver being for long-range wireless communications (e.g. 3G) with a remote system 108. The first processor receives a user ID of a second user and one or more further inputs, at least a first input being received via the first wireless transceiver and including item data corresponding to an item. The first processor transmits to the remote system via the second wireless transceiver, at least the item data, associated with the user ID. The system may further comprising an intermediate unit 118, the intermediate unit including a second processor and, coupled thereto, a reader and a wireless transmitter, the reader and/or wireless transmitter being for short-range communication. The second processor may, upon reading the user ID from an ID card of the second user by the reader, transmit the user ID user via the wireless transmitter. The reader, wireless transmitter and/or the first wireless transceiver may comprise a near field communication (NFC) device. |
