Abstract: A card substitution prevention method for a self-service terminal includes performing, by a card feeding portion of the self-service terminal, an alteration operation in the case that a card exists in a card reader of the self-service terminal, to make the card feeding portion unable to receive another card and prevent the another card from being placed in the card feeding portion. Also provided is a card substitution prevention apparatus for a self-service terminal. The method can effectively protect a card of a customer and prevent the card of the customer from being stealthily substituted, thereby improving service quality of a self-service terminal and maintaining trade credit of a merchant.

Abstract: A sheet-type medium separating apparatus applicable in a self-service financial device for reliable sheet-by-sheet separation of an entire stack of banknotes. The apparatus includes a pickup roller component; a reversal roller component; and a separation roller component, where the reversal roller component includes a reversal roller, the reversal roller is fitted onto a reversal roller shaft via a one-way bearing, the reversal roller is provided with an inner sleeve cylinder fixed with the one-way bearing and a reversal roller sleeve sleeved onto the inner sleeve cylinder and capable of moving axially and flexibly. The separating apparatus allows for automatic adjustment of the meshing clearance between the reversal roller and the separation roller on the basis of the thickness of sheet-type media to be separated, thus effectively solving the problem of the sheet-type media being jammed or torn.

Abstract: A card substitution prevention method for a self-service terminal comprises: when a card exists in a card reader of a self-service terminal, a card entering portion of the self-service terminal performing an alteration operation, so that the card entering portion cannot receive a card and the card cannot be placed into the card entering portion. Also provided is a card substitution prevention apparatus for a self-service terminal. The method can effectively protect a card of a customer and prevent the card of the customer from being stealthily substituted, thereby improving service quality of a self-service terminal and maintaining trade credit of a merchant.

Abstract: The present invention provides thin film dielectrics, and methods of producing them, with high-K performance, and high breakdown field strength and with self-healing breakdown properties. In one aspect there is provided a multilayer dielectric film having an interrupted grain structure, comprising a first sub layer comprising a first dielectric material having a columnar grain structure having a first orientation, a second sub layer comprising a second dielectric material on top of said first layer having an equiaxed grain structure that is different from the first sub layer and a third sub layer comprising third dielectric material on top of said second layer having a microstructure that is different from the second sub layer to provide an interrupted grain structure through said multilayer dielectric film.
