  • Patent number: 8915434
    Abstract: A card reader guide for use in a fascia of a self-service terminal is described. The card reader guide defines a card reader aperture extending in a first direction through which a customer may insert a data card. The card reader guide also comprises: a first protrusion extending (i) along part of the card reader aperture through which a magnetic stripe of the card passes, and (ii) towards the customer, wherein the first protrusion defines a stripe path in registration with the magnetic stripe of the card as the card is inserted by the customer; a second protrusion, opposite to, and aligned with, the first protrusion, and extending (i) along the part of the card reader aperture through which the magnetic stripe of the card passes, and (ii) towards the customer; and a magnetic reader detector located in the first protrusion at the stripe path.

  • Patent number: 8704633
    Abstract: A method of preventing fraud at a self-service terminal is described. The method comprises: receiving a signal from an electromagnetic sensor located in the vicinity of an electromagnetic signal transmitter; monitoring a drive signal being delivered to the electromagnetic signal transmitter; and comparing the drive signal with the electromagnetic sensor signal. The method then ascertains if a state of the electromagnetic sensor signal is inconsistent with a state of the drive signal; and triggers an alarm when the state of the electromagnetic sensor signal is inconsistent with a state of the drive signal.

  • Publication number: 20050239379
    Abstract: Miracle Sand is a clear, biodegradable, zero volatile organic composition, environmentally safe spray product designed for an easier, safer and non-hazardous way of preparing, sanding and removing various flaws on freshly coated and/or previously coated wood, metal, masonry, drywall and plastic surface substrates without the mess and exposure to unsafe dust, sand particulate that can cause atmospheric health risks. Sanding sponges or sand paper are used with Miracle Sand in the flaw removal process; said process is as follows: Spray Miracle Sand liberally on the paint flawed surface. Wait less than a minute, then sand the paint flawed area with the sanding sponge or sand paper. When the flaw is removed, wipe off the remaining solution and sanding debris. Repeat entire process if surface is not smooth. Let surface dry, then coat with any finishing product.

  • Publication number: 20050097633
    Abstract: The present invention provides compositions and methods for regulating expression of heterologous nucleotide sequences in a plant. Compositions include a novel nucleotide sequence for a root-preferred promoter for the gene encoding CRWAQ81. A method for expressing a heterologous nucleotide sequence in a plant using the promoter sequences disclosed herein is provided. The method comprises stably incorporating into the genome of a plant cell a nucleotide sequence operably linked to the root-preferred promoter of the present invention and regenerating a stably transformed plant that expresses the nucleotide sequence.
