Abstract: A wireless communication device such as a payment reader has a wireless communication interface and is able to establish wireless pairing with an interactive electronic device such as a merchant device running a point of sale application. In order to establish pairing, the wireless communication device accesses an identifier. The identifier is transmitted to the interactive electronic device via the wireless communication interface, and the interactive electronic device sends the identifier to a pairing server. The pairing server retrieves a passkey based on the identifier and sends the retrieved passkey to the interactive electronic device via a secure connection. The wireless communication device and the interactive electronic device establish wireless pairing based on the retrieved passkey.

Abstract: Techniques and arrangements for capturing payments in cases involving a failed authorization. In some instances, a point-of-sale (POS) device may process a transaction while operating in an offline mode, and then send information regarding the transaction to a remote service after transitioning to an online mode. The remote service may attempt to authorize a payment instrument tendered to satisfy a cost of the transaction. In instances in which the payment instrument is declined, one or multiple payment-capture techniques may be utilized to capture a payment that satisfies at least a portion of the cost of the transaction.

Abstract: The top cover defines a first fastener receiving void that is disposed along the direction of material flow between the forward ramp portion and the rear edge. The top male angled surface of the top cover defines a first material flow groove that extends along the direction of material flow, and includes a first flow ramp. The first material flow groove is disposed adjacent along the lateral direction and the direction of material flow to the first fastener receiving void.

Abstract: Systems and methods for pairing a payment object reader with a computing device are described. An example method includes detecting, by a computing device and while in a pairing mode, a plurality of payment object readers. Each of the plurality of payment object readers is configurable to be paired wirelessly with the computing device. Each of the plurality of payment object readers outputs a signal strength representative of a location of the payment object reader relative to the computing device. The computing device tracks respective signal strengths of the plurality of payment object readers over time. Based on a determination that a change in a signal strength of a particular payment object reader of the plurality of payment object readers represents movement of the particular payment object reader relative to the computing device, a wireless communication channel is established between the particular payment object reader and the computing device.

Abstract: A cutting edge tip includes an attachment portion defining an adapter receiving void. A working portion extends forwardly from the attachment portion. A first lateral end portion is disposed along the lateral direction, the first lateral end portion defining a first lateral end surface that jogs laterally. Also, a second lateral end portion is disposed along the lateral direction opposite of the first lateral end portion. The second lateral end portion also defines a second lateral end surface that jogs laterally.

Abstract: A spring loaded retainer includes a lug receiving portion defining a first maximum outside dimension, the lug receiving portion also defining a lug receiving slot that extends partially through the lug receiving portion, forming a first sidewall, a second sidewall, and a catch surface connecting the first sidewall to the second sidewall. A drive portion defines a second maximum outside dimension, and a first flat is disposed on the outside of the lug receiving portion proximate to the first sidewall or the second sidewall.

Abstract: A wear member includes a forward working portion that is disposed along its longitudinal axis including a closed end, and a rear attachment portion that is disposed along the longitudinal axis including an open end with an exterior surface, and an interior surface. The interior surface defines an interior counterbore with a major diameter, and a minor diameter. A ratio of the major diameter to the minor diameter ranges from 1.8 to 2.2.

Abstract: A lock assembly for attaching a wear member to a base includes a retaining block with a spring attached to the retaining block that fits into an aperture of the base. A lock pin fits into the aperture of the wear member, and the aperture of the retaining block, retaining the wear member onto the base. The lock pin engages the spring that prevents unintentional rotation of the lock pin so that the lock pin is trapped in the aperture of the wear member, preventing its unintentional removal.

Abstract: In some examples, a system and method for pairing a payment object reader with a point-of-sale (POS) terminal is described herein. The method includes determining, by a wireless transceiver, a first value of signal strength corresponding to a current position of the payment object reader and a second value of signal strength corresponding to a new position of the payment object reader. The POS terminal then identifies the first wireless device as an intended candidate for pairing with the second wireless device based on variation in signal strength from the first value of signal strength to the second value of signal strength. Accordingly, the POS terminal establishes a wireless communication channel between the POS terminal and the payment object reader device for exchange of information. Once paired, the payment object reader allows the POS terminal to accept payments from a customer.

Abstract: Examples, methods and systems described herein may include determining, by a payment processing system, whether a second payment mechanism may be used to perform a payment transaction when a first payment mechanism is preferred and/or when the first payment mechanism has failed. Determining to use the second payment mechanism can be based on (i) an analysis of a communication status indicator received from a point-of-sale (POS) terminal that indicates which payment mechanisms are capable of communicating with the POS terminal, (ii) data received from the POS terminal that is associated with a read of a payment object, and/or (iii) an allowance criterion.

Abstract: A payment handling system may operate to handle payments for the cost of a transaction in which one or more devices operate in an offline mode. The payment handling system may allow for merchant devices to make modifications to local versions of an open ticket while in an off-line mode. When a merchant device subsequently enters an online mode, the systems and techniques may operate to reconcile differences between the local versions of the open ticket.
