The transaction method is for secure payment by credit cards or debit cards for goods or services with the use or mobile devices. The payment authorization center delivers a public portion of the authorization token to the service provider via the existing communication channels and the private portion of the authorization token is delivered to the mobile device via SMS or USSD or e-mail short message. The mobile device delivers the private authorization token to the service provider via a private local network based on bluetooth, infrared or other short radio frequency based technology. The credit card or debit card number is never revealed and a temporary card token replaces it.

The present invention is directed to incrementing a well service rig in such a manner that activity-based and / or time-based data for the well site is recorded. The acquired data can be transmitted via wired, wireless, satellite or physical to a data center preferably controlled by the work-over rig owner, but alternately controlled by the well owner or another. The data can thereafter be used to provide the customer a detailed invoice or a searchable, secure web-based database. With such information, the customer can schedule other services at the well site. Further, the customer will have access to detailed data on the actual service performed. The present invention fosters a synergistic relationship among the customer and the service companies that promotes a safe environment by monitoring crew work activities and equipment speeds; improving productivity; reducing operation expenses through improved job processes; and better data management and reduced operational failures.

The invention provides an oil well casing gas collecting device. An oil pumping pipe, an oil pumping rod and a casing are arranged in an oil well, the oil pumping rod is connected onto an oil pumping unit, and the oil pumping unit pumps crude oil from the oil pumping pipe and transports the crude oil to an oil transportation pipe. The device comprises a casing connecting pipe, a one-way valve A, a boosting pump, a one-way valve B and an oil pipe connecting pipe. The boosting pump includes a connecting rod, the upper end of the connecting is fixedly connected with a pressure arm, the upper portion of the oil pumping rod is fixedly connected with a pressure button, and the pressure button is located above the pressure arm. When the boosting pump is installed, the connecting rod is parallel to the oil pumping rod, and the pressure arm is intersected with the connecting rod but is not connected with the connecting rod. When the oil pumping rod is lifted up under the driving of the oil pumping unit, casing gas drives a piston, the connecting rod and the pressure arm to move upward under the action of self pressure. When the oil pumping rod moves downward under the action of self gravity, the pressure button presses the pressure arm to drive the connecting rod and the piston to move downward, and compressed casing gas in a compression cylinder enters the oil transportation pipe. By means of the oil well casing gas collecting device, a series of problems including difficulty in traditional oil well casing gas recovering, energy waste, environment pollution, safety hazard and the like are solved. Therefore, the oil well casing gas collecting device has obvious economic benefit and environmental-protection benefit.

In an optical transmission node network in which a first optical transmission node is connected with a second optical transmission nodes through an optical fiber cable and automatic optical output (APSD: Automatic Power Shut-Down) control is activated, after the APSD control is brought into an inhibited status, if an optical conduction to the second optical transmission node is detected, the APSD control inhibited status is canceled. In this way, if an optical transmission fiber is resorted (reconnected) after optical output power measurement or the like is carried out, the APSD control inhibition status (invalid status) is canceled for automatically restoring the APSD control activated status. Thus, optical output can be prevented from being inadvertently emitted at a high energy level from the optical fiber cable.
