Contactless payment technologies

There are three in total. Which one is used by the gadget depends on its OS.

Overview of watches with nfc Apple Watch

The smart watch chip from Apple of the latest generations is not only in the improved filling, but also in the improved payment method through the NFS.

Now both gadgets use individual Wallet applications that are not connected to each other. Although the Watch still requires pairing with an iPhone, you can link a separate card to each device. You don’t need a cell phone to pay.

Samsung Gear watch review

Models of the S3 series have a classic appearance, while boasting all the necessary set of options.

The gadget works with NFS using Samsung Pay technology. The latest models can be synchronized not only with branded smartphones, but also with devices of other brands (except Apple).

Contactless payment by watch from Samsung is no different from others. But the main feature is in MST. The abbreviation stands for Magnetic Secure Transmission. The development allows the device to create a field that imitates a magnetic strip located on a bank card. This means that using the clock you can pay in outdated terminals.

Both options (NFS and MST) can be used by owners of Gear S3 Classic, Frontier and above. The main condition is a smartphone on Android at least 4.4 with RAM above 1.5 gigabytes.

How to use:

1. Synchronize watch with phone.
2. Open the Samsung Gear app.
3. In the settings, select the item with the payment technology and confirm the plugin download, if required.
4. Log in to Samsung accounts.
5. By clicking the appropriate button, add a card and enter the required information.
6. Check if all the data is correct and enter the code from the bank. It will come via SMS or online banking application.
7. Provide an example of your signature. This is sometimes needed to pay for purchases by the clock using MST.
8. Wait until the card is verified. The process usually takes no more than ten minutes.

After that, you can add other bank cards. To do this, you only need to repeat steps 5-8.

With a regular watch with a PayPass chip

Paypass is built into some classic accessories. They are also suitable for contactless payment. A bright representative of the advanced classics is Watch2pay, which is attached to MasterCard.

A plastic card is also issued for withdrawing funds from ATMs and making purchases on the Internet.

Interesting: children’s smart watches, although not so advanced, can do a lot. So, with their help, parents will always know where their child is. And the baby will be able to receive and make calls with one touch.

What is the difference between NFC and Bluetooth

Both options are designed for wireless data transmission. But bluetooth is designed to communicate one device with another. This limits his powers. You cannot pay for purchases using it. But the latest versions of Bluetooth can operate within a radius of 100 meters, and the chip — a maximum of 10 cm.

There is also a difference in connection speed and connection establishment. The NFS has 0.1 seconds, and pairing with another device is carried out automatically. Bluetooth pairing may take several minutes and is preconfigured.

Using gadgets with NFC for payment is easy: the setup does not take much time, and the transaction itself takes less than a second.
