Abstract: Computer-implemented method and system are provided for verifying a financial instrument. The method comprises receiving, via a user interface, the identification of one or more financial instruments. A transaction processor initiates at least one transaction using a variable detail and saves the variable detail in a database as a stored detail. A requested detail relating to the at least one transaction is received via the user interface and the transaction processor compares the stored detail with the requested detail. The use of the financial instrument is authorized if stored detail matches the requested detail.

Abstract: Computer-implemented method and system are provided for verifying a financial instrument. The method comprises receiving identification of a source of funds; generating, using at least one processor, a series of verifying transactions involving the source of funds, transaction details of the series of verifying transactions varying from one transaction to another; storing the variable transaction details; initiating the series of verifying transactions; receiving provided transaction details from a user; comparing the variable transaction details with the provided transaction details; and selectively approving the use of the source of funds by the user, based on a result of the comparison of the variable transaction details with the provided transaction details.

Abstract: Computer-implemented method and system are provided for verifying a financial instrument. The method comprises performing a plurality of transactions using a source of electronically exchanged value identified by a user, recording details of the plurality of transactions, inviting the user to identify the details to a verification system, and verifying the source of electronically exchanged value based on the details provided by the user to the verification system.

Abstract: A system and method for verifying a financial instrument or a user's authorization to use a financial instrument. The system initiates one or more verifying transactions involving the instrument, with details that may vary from one transaction to another, such as the type of transaction (e.g., deposit, credit, debit), amount of the transaction, number of transactions, the merchant or vendor name or account for the transaction, and so on. Selected details, particularly variable ones are saved in the system. The user accesses information regarding the transaction, by accessing it on-line, via telephone, in a monthly statement, etc. The user then submits the requested details to the system, which compares them to the stored details. If they correspond, then the user may be allowed to use the instrument (e.g., for a purchase, a fund transfer).

Abstract: A modular encoder and switch assembly includes a first module containing the rotor and contact elements of an electrical encoder, and a second module that contains a switch. The two modules are axially aligned and joined together in tandem. The encoder and the switch are actuated by a common shaft that is rotatable to actuate the encoder and movable axially to actuate the switch.
