Pay with a smile

09.09.2017

Payment system Alipay and international restaurant chain KFC have launched a new payment method.

The technology called Smile to Pay was developed by Ant Financial, a subsidiary of Alibaba Group. To pay for an order in the terminal, the buyer just needs to smile into the lens; the developers claim that it takes about two seconds to scan a face (using a 3D camera), at which time a special algorithm checks the person’s identity (the buyer must also enter the mobile phone number linked to the Alipay wallet). The beta version of Smile to Pay was introduced in 2015 by Jack Ma, the founder of Alibaba.

Ant Financial notes that they have combined complex algorithms and a 3D camera in the development; this helps to prevent "biometric fraud".

According to the developers, the algorithm is able to recognize shadows and other details of the environment - this is necessary in order to understand whether the person making the payment is real (or scammers use photos or videos to deceive the payment system).

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Artificial glacier against global warming 03.05.2017

American scientists have proposed to fight global warming by growing artificial glaciers and thus stop negative trends in the environment.

During the construction of a man-made glacier, artificial snow will be used. According to scientists, to protect the artificial block from exposure to sunlight, you need a layer of several centimeters of such snow. The glacier is expected to grow within 20 years and reach a height of about 800 meters.

In case of successful implementation of this project, such glaciers are planned to be grown all over the world. At the same time, the bright dreams of American scientists are not shared by some economists who believe that the project will cost a fabulous amount. But apparently such a payment will have to be made to humanity for climate change on Earth.
