What is AVS? AVS stands for Address Verification System, an added level of credit card security provided by credit card issuers to detect suspicious credit card usage. Simply put, itâs a way for business owners to check if the person presenting a credit card as payment for your merchandise or services is actually the authorized cardholder.
In 1712 Newcomen invented the world's first successful atmospheric steam engine. The engine pumped water using a vacuum created by condensed steam. It became an important method of draining water from deep mines and was therefore a vital component in the Industrial Revolution in Britain.
James Watt then took over the reins, and the development of the steam engine really began to gather pace. The Scottish engineer noticed from Newcomen's design that a vast amount of heat energy was escaping from the mechanism heating the cylinders.
