Abstract: A device for dispensing volatile liquids has a head and a body and can be formed of an absorbent material. A volatile liquid is applied to the body of the device so that the body absorbs the volatile liquid. To attach to or engage the volatile liquid dispensing device with a support structure, a tab, cut into the head of the device, is pulled out from the head along a spiral incision and engaged with a support structure. The recoil inherent in the spiral incision further secures the device to the support structure. As the liquid evaporates, the volatile liquid disperses into the atmosphere.

Abstract: The device of the present invention is a stand alone radio frequency identification (RFID) reader/writer device comprising a micro controller having non-volatile data memory, an RFID module, at least one input/output port, and a display. The device of the present invention is fully configurable and may serve as a multi-functional transaction sentry, i.e., a ticket taker, a money or point collector, a money or point dispenser, an access controller, a balance inquiry station, a transaction logger, etc. The method of the present invention comprises steps for configuring, operating and collecting data from the RFID reader/writer device of the present invention. The configuration, operation or data collection from the RFID device of the present invention may be performed by using either the RFID module or the at least one input/output port.
