  • Patent number: 10719833
    Abstract: A device with one or more processors, memory, and two or more communication capabilities obtains, from a payment module, an authorization request via a first communication capability (e.g., Bluetooth). The device sends, to a server, the authorization request via a second communication capability distinct from the first communication capability (e.g., cellular or WiFi technology). In response to sending the authorization request, the device obtains, from the server, authorization information via the second communication capability. After obtaining the authorization information, the device detects a trigger condition to perform a transaction with a payment accepting unit associated with the payment module. In response to detecting the trigger condition, the device sends, to the payment module, at least a portion of the authorization information via the first communication capability.

  • Patent number: 10438208
    Abstract: System and methods are disclosed for interactions with unattended retail machines (“URMs”) using detectable trigger conditions and limited-scope authorization grants. An exemplary method is performed at a mobile device and includes: receiving, via a communications unit, a broadcasted signal from an electronic payment device coupled with an URM. The broadcasted signal includes a request to authorize funds that are associated with a user of the mobile device for use at the URM. The method further includes: (i) sending the request to a server via the communications unit, (ii) receiving, from the server, an authorization grant (e.g., the grant expires if predetermined criteria are satisfied), and (iii) detecting a trigger condition to initiate a cashless transaction with the URM. In accordance with a determination that the predetermined criteria haven't been satisfied, the method includes: initiating the cashless transaction with the URM by sending the authorization grant to the electronic payment device.

  • Patent number: 10397876
    Abstract: Wireless devices are provisioned using multiple factors. As part of a wireless detection phase, multiple wireless communications are received that were transmitted by multiple wireless devices. Individual wireless devices are distinguished from each other among the multiple wireless devices based on a distinguishing feature of each of the multiple wireless communications to obtain a provisional set of wireless devices. As part of an electrical load detection phase, one or more wireless devices connected to an electrical power circuit are identified based on time-based measurements of electrical power consumed by electrical loads on the electrical power circuit and/or powerline communications received via the electrical power circuit. The provisional set of wireless devices obtained by wireless detection may be filtered to obtain a filtered set of wireless devices that excludes wireless devices of the provisional set not connected to the same electrical power circuit.

  • Patent number: 9256873
    Abstract: A payment module includes: one or more processors, memory, a first interface module configured to couple the payment module with a control unit of an offline-payment operated machine, and a short-range communication capability for communicating with one or more mobile devices each including a complimentary short-range communication capability and a long-range communication capability. The payment module receives a transaction request via the short-range communication capability from a mobile device to perform a transaction with the offline-payment operated machine. The payment module validates the transaction request to verify that the mobile device is authorized to initiate payment for the transaction by a remote server via the long-range communication capability.

  • Publication number: 20150170145
    Abstract: A payment module with one or more processors, memory, and a first communication capability is coupled with a payment accepting unit (e.g., an automatic retailing machine for dispensing goods and/or services). The payment module obtains a notification indicating completion of a transaction, and an amount thereof, performed by user of a device at the payment accepting unit. In response to receiving the notification, the payment module generates and stores transaction information based on the notification; and sends the transaction information to the device via the first communication capability (e.g., BLE). After sending the transaction information to the device, the payment module: deletes the stored transaction information if acknowledgement information is received from the device within a predetermined time period; and maintains the stored transaction information if the acknowledgement information is not received from the device within the predetermined time period.
