Abstract
A method of verifying the identification of fluids to be supplied successively through a fluid-supply hose that selectively connects to successive movable, RFID-tagged fluid containers includes providing an RFID reading unit including an antenna. A sequence of reference container identification codes is received. A container-present indication indicating one of the containers is positioned so that its RFID tag is in the antenna range is received. In response, the RFID tag of that container is read using the RFID reading unit to determine an identification code of the container. A controller automatically verifies the determined container identification code against the first reference identification code in the sequence using a controller. The starting through verifying steps are repeated, using successive values from the sequence in the verifying step, until all values in the sequence have been verified against container identification codes read using the RFID reading unit.
