Paying with your phone or NFC (Near Field Communication) works by utilizing a technology called RFID (Radio Frequency Identification). This technology works by having two components: an RFID tag and an RFID reader. The RFID tag is embedded in the phone or payment device and contains a unique ID number that is used to identify the user. The RFID reader reads the unique ID number, and then sends it to the payment processor to complete the transaction. NFC specifically uses a shorter range of communication and is commonly used for payments and data transfers between two devices.
How did it all started?
Google, Apple, and Garmin all introduced their own payment platforms that utilized NFC technology. Google was the first to introduce NFC payments with its Google Wallet platform in 2011. Apple followed in 2014 with its Apple Pay platform, which allowed users to securely store credit card information in their iPhones. Finally, Garmin launched its own contactless payment platform, Garmin Pay, in 2016, which allowed users to securely store payment information on their Garmin devices such as smartwatches. All of these payment platforms use NFC technology to securely transmit payment information between the mobile device and the payment terminal.
POTENTIAL THREATS
Although, NFC technology is a great way to make transactions and payments more secure and convenient, there are some potential threats associated with its usage. One of the biggest threats is the possibility of hackers intercepting NFC signals and gaining access to sensitive financial information. Additionally, if a device containing an NFC chip is lost or stolen, there is the potential for someone else to access the data on that chip. Finally, due to its proximity-based nature, NFC technology can be used to track users, which could be a privacy concern, at least to some of us.
To sum up, Near Field Communication (NFC) is a secure and convenient technology used to make payments and transfer data between two devices. Google, Apple, and Garmin have all introduced payment platforms using NFC technology, which helps to make transactions more secure and convenient. However, there are potential threats associated with the usage of NFC technology, which we should bare in mind. Therefore, users should take extra precautions when using NFC technology for payments and data transfers.
Ultimately, I wonder what could be a new usage of NFC technology in the near future. Write in the comment section down below if you have any ideas.

This can happen if an attacker is able to intercept communication between the NFC device and the payment terminal. or if a device with an NFC chip is lost or stolen. Additionally, due to its proximity, NFC technology can be used to track users. This may be a privacy concern. to mitigate these risks. Users need to take extra precautions when using NFC technology for payments and data transfers, such as keeping their devices secure and aware of their surroundings when making transactions.
NFC is definitely one of the wireless technologies that changed our lives greatly. Personally I would like to see more innovation in the use of NFC as there haven’t been many new ideas floating around in the tech sphere. As Thananon mentioned above. It’s important to be aware of the dangers of using NFC in your daily lives. One good safety equipment that’s widely available are wallets made from materials that block NFC waves coming through them. Making it impossible for a near field attacker to take information from your NFC cards.
I agree with Krystian, that this is one of the most revolutionary wireless technologies used on a global scale. I can’t imagine paying otherwise than with my phone.
