Abstract: Authentication method and systems using RFID-enabled payment cards are disclosed herein where a server receives a request corresponding to authorization of a payment associated with a payment card from an electronic terminal. The server identifies an electronic device of a user associated with the payment card. The server then transmits an instruction to the electronic device to cause an RFID reader of the electronic device to determine whether an RFID tag corresponding to the payment card is located within a predetermined proximity to the electronic device. When the payment card is located within the predetermined proximity, the server executes a first authentication protocol. Moreover, when the payment card is not located within the predetermined proximity, the server executes a second authentication protocol, wherein the second authentication protocol is more restrictive than the first authentication protocol.

Abstract: A railing system for porches, decks, steps, ramps and the like having a top and bottom rail formed of wood containing a wood preservative that is corrosive to aluminum, aluminum alloys and the like. The system has hollow metal balusters formed of metals which may be harmed by the corrosive effects of the wood preservative. The metal balusters are protected from the corrosive effects of the wood preservative by inert fixtures interposed between the wooden components of the railing system and the metal of the balusters. The fixtures may be joined by runners that simplify installation of the railing system.

Abstract: A railing system for porches, decks, steps, ramps and the like having a top and bottom rail formed of wood containing a wood preservative that is corrosive to aluminum, aluminum alloys, paint and the like. The system has hollow metal balusters formed of metals which may be harmed by the corrosive effects of the wood preservative. The metal balusters and, if painted, the paint is protected from the corrosive effects of the wood preservatives by inert connectors interposed between the wooden components of the railing system and the metal or paint of the balusters. The connectors are also useful with untreated wood such as cedar or with synthetic materials.

Abstract: A decorative scroll for a round baluster. The scroll is preferably sand cast of aluminum and attached to the baluster with screw through a plate having centering elements for secure three-point contact. The scroll with the baluster for use in emulating a wrought iron fence or railing.
