Abstract: The invention provides an RFID circuit for use with new or pre-existing antitheft tags. An RFID pin replaces the current pin on antitheft tags that retailers already own. The RFID circuit is incorporated into or secured to, the pin structure. By replacing the current pin used on antitheft tags with a low cost RFID pin, existing antitheft tags can be inexpensively upgraded to antitheft tags that are also capable of use as inventory management and/or enhanced theft control devices.

Abstract: An anti-theft tag with a locking mechanism that cannot be removed without breaking the lock. The anti-theft of tag has a removable lock that can be replaced after it is broken. The securing pin secures the lock in place in the first part of the tag. When the securing pin is withdrawn, the locking mechanism can be detached from the anti-theft tag. An optional method is provided in which the detacher arm channel is sealed to prevent access by a pick. The remaining parts of the tag, other than the lock, can be recycled. An alternative anti-theft tag uses a resettable locking mechanism. A detacher arm moves the lock from a locked to an unlocked position. Once unlocked, the lock remains in the unlocked position until reset with a key. A key aperture is hidden under the pin securing means.

Abstract: A method and system are provided for executing a transaction relating to a first futures contract. The first futures contract involves a tradable asset, such as crude oil or another commodity, and a first contract price and a first settlement price expressed in a first currency, such as U.S. dollars. The first settlement price is updated on a periodic basis, typically daily. The method involves providing a second futures contract having an underlying instrument that includes the first futures contract. The second futures contract includes a second latest possible delivery date and a second contract price and a second settlement price that are denominated in a second currency. The second settlement price is updated periodically. A periodic mark-to-market operation credits or debits a buyer of the second futures contract based on the periodic update to the second settlement price.

Abstract: An anti-theft tag that uses single or dual detacher arms. A first detacher arm moves a locking arm aside such that a release arm can rotate to separate the arms of a C-clip that secures the pin on the securing member. Either the first detacher arm, or an alternative second detacher arm then presses the release arm to rotate it. When the release arm is rotated, a wedge on the release arm exerts pressure against the arms of the C-clip to force them apart which causes the securing member pin to be released. The securing member pin cannot be released by the anti-theft tag unless the detacher arms are inserted in sequence. An alternative anti-theft tag provides spring loaded door button at the entrance to the detacher arm chamber. The door button guides an unauthorized tag pick away from the entrance to the detacher arm chamber and routes it toward a dead-end. The detacher arm will press a spring loaded door button to an open position and allow access of the detacher arm into the detacher arm chamber.

Abstract: A dual use anti-theft tag is provided which has a structure that can be used as a reusable anti-theft tag, or as a single use recyclable anti-theft tag. The anti-theft tag uses a conventional ball bearing lock which can be opened by a mechanical probe, or opened magnetically. In a first configuration, the anti-theft tag uses a reusable locking mechanism. In this configuration, the lock can be repeatedly moved from a locked to an unlocked position. In a recyclable configuration, an optional spring lock keeps the anti-theft tag in the unlocked position once opened. An advantage of the invention is that the same anti-theft tag structure can be used for both embodiments.
