Google launched the Android Pay payment system
The official Google blog announces the launch of the Android Pay payment system in the USA. From a technical point of view, you can use the new product with a smartphone with KitKat 4.4 or later, which also supports NFC. A special application should appear during this week. It will support payment cards American Express, Discover, MasterCard and Visa, and you can pay using Android Pay in more than a million retail outlets in America.
One cannot but notice that confusion can arise with Google payment applications. Google Play already has Google Walletreleased a few years ago. This very one - the “old wallet" - will be updated in the near future to Android Pay as part of the launch of the payment system. However, the Google Wallet brand is not going anywhere: the app store has a new Google Wallet (new) . which will continue to be supported by the search giant and will be designed to send money to user accounts using a smartphone. To do this, the application will need to be linked to your bank account, and you won’t be able to pay with it in Android Pay terminals.
The Android Pay application interface looks like this:

About a month ago, Samsung announcedthat its own Samsung Pay payment system is more reliable than its future competitor from the bowels of Google. We are talking about the fact that a number of new Korean company devices - Galaxy S6, S6 Edge, S6 Edge + and Note 5 - are equipped with MST (Magnetic Secure Transmission) technology. Thanks to this, Samsung devices can generate a dynamically changing magnetic field. In other words, if you bring the smartphone to a regular payment terminal where you can pay with cards with magnetic tape, it acts on the reader of the terminal as if a “real” plastic card was actually drawn through it. Thus, Samsung Pay provides an additional convenience - with its help it will be possible to pay where there is no NFC terminal yet.
