Abstract: Gateway devices can use dual cellular interfaces, each assignable to at least one of a plurality of network services, to provide reliable communications for client machines. A gateway device can use one of the dual cellular interfaces assigned to a first network service as a primary interface and the other assigned to a second network service as a hot backup interface. The backup interface remains connected to a cellular network while communications are routed on the primary interface. Accordingly, the gateway device can rapidly switch communications between from the primary interface to the backup interface. Applications, for example, for ATM payment processing, vending machine telemetry, point of sale payment processing, kiosk internet connectivity, remote monitoring and control, mobile or electronic health, and remote information displays, may run on the gateway devices, on servers, on user devices, or a combination of these devices.

Abstract: A combined primary label and secondary label comprises a first piece of paper, a first release coating disposed on a portion of the first piece of paper, a second piece of paper, a second release coating different from the first release coating and disposed on a portion of the second piece of paper.

Abstract: A receipt and label roll comprises a core and a web having a longitudinally-extending axis and wound on the core along the axis. The web includes (i) a substrate having a front side and a back side opposite the front side, (ii) a thermally-sensitive coating disposed on the front side of the substrate, (iii) adhesive disposed on a portion of the back side of the substrate along the web axis, and (iv) a release coating disposed on the front side of the substrate along the web axis to prevent the adhesive from sticking to the front side of the substrate when the web is wound on the core. The web further includes (v) a longitudinal weakened structure extending along a direction parallel to the web axis and dividing the web into a first web portion on which the adhesive is disposed and a second web portion which is substantially devoid of adhesive.
