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 system for protecting storage tank soil side bottoms against corrosion includes a pipe system comprising non-perforated inlet pipes and perforated pipes connected thereto. A sleeve container having solid VCI compounds therein is inserted into the perforated pipes. The sleeves are permeable to vapors emitted by the solid VCI compounds and flow through the pipe to a perforation where they are admitted into an area beneath a storage tank so that they can contact the tank bottom (soil side) and protect the same from corrosion. Alternatively, solid SCI compounds can be used in combination with VCI compounds. The corrosion protection system is designed to be used with aboveground storage tanks. This includes, but is not limited to, single bottom tanks: newly installed or existing tanks undergoing bottom replacement or installation of double bottoms.
