Samsung Pay: Understand What It Is And How It Works

Launched in August 2015 and arriving in Brazil only in 2016, Samsung Pay is the solution developed by the homonymous South Korean giant to make payments by approach using a device. The system works through secure and well-established technologies in the market, such as NFC and MST — “Communication by Near Fields” and “Secure Magnetic Transmission”, respectively, in free translation of the acronyms in English.

However, that’s not Samsung Pay’s only strength. In the mobile app, the user can register several debit and credit cards, as well as other services such as Food Ticket, to organize and facilitate their financial life during payments. To top it off, there is still the possibility to create a digital account, get rewards through points and much more.

To help users, TecMundo has prepared a guide with the most important information about Samsung Pay. Check out:

How it works?

In detail, Samsung Pay “transforms” an enabled device into a traditional “credit card”. For this, it is necessary that the user previously register the credit or debit cards that they want to use and check if their device has support for both the application and for payments by approximation.

Next, just open the application and bring the device closer to the payment terminal to complete the transaction. The process is very similar to that found in similar solutions like Google Pay and Apple Wallet, as they both work through NFC, but only Samsung Pay has the use of MST as an alternative — thus increasing its compatibility.


Despite having basically the same purpose, NFC and MST technologies work in very different ways. Devices with NFC (or CCP, for its acronym in Portuguese) are only able to communicate with other devices that also have this support, sending data within a frequency of 13.56 MHz.

For payments with MST, the contact must be made where the magnetic card is inserted, while with NFC it only takes a touch.

On the other hand, the MST (or TMS, if translated into Portuguese) can communicate with any type of terminal, as it uses a small magnetic field to “trick” you and simulate that a credit card was used in the traditional way. there. The technology is unique to Samsung and therefore its implementation is limited to its devices.

Availability and support

Samsung Pay is available for Android and iOS devices. However, part of its features are limited in mobile phones that are not Samsung — such as, for example, the pay-by-approximate itself. These devices only support the Samsung Pay Mini, a “compact” variant of the original tool.

Controversial, the restriction may sound a bit strange to interested users who don’t own a Samsung device, but it can be explained, in part, by the absence of Knox — a proprietary security framework from the South Korean, built directly into its operating system. . The feature is able to protect branded cell phones in several layers, offering more reliability in their use.

However, it is still possible to enjoy other features of Samsung Pay even without owning a South Korean device. Among them are the possibility of creating digital accounts for individuals and companies, issuing and paying slips, making deposits and withdrawals at lottery agencies and much more. In addition, there is also the loyalty program that guarantees rewards for users who use the services.
