Near Field Communication (NFC) is a proximity technology that allows devices to communicate by bringing them close together (usually by tapping or placing them nearby). The "near field" in NFC means the devices need to be within a few centimetres of each other to communicate.

Imagine your devices have invisible strings connecting them. When you tap them together, these strings allow data to travel between the devices. It's a quick and secure way for gadgets to talk to each other.

Prominently, NFC has been used in payment and transportation through applications like contactless payment and tap-to-pay.

But there are a lot more to it…

You can share photos, videos, or contacts by tapping your devices together or simply tap your phone on the wireless gadget to pair them together instead of going through complicated setup processes.

How about tapping to connect with the real world around you? With Loop, NFC plays a role in making physical interaction and serendipity a magical experience. Instead of exchanging contact information, people can tap their smartphones to someone’s belongings to communicate directly without disclosing personal details. You can also skip manual registration by tapping to join a group or event. Soon, Loop can also streamline check-ins, drive-thru, redemption, loyalty program, inventory, and more.

What’s the difference between NFC and QR code?

• Dynamic vs static: NFC technology allows for dynamic interaction. The information stored in an NFC chip can be adjusted and updated in real-time. This means that the same NFC tag can offer different content or functionality at different times. For example, Loop device can be switched between Owner’s Loop and Group Loop. QR code, on the other hand, is static once it's generated and printed. The information encoded in the QR code remains the same until a new code is generated.
• Speed and convenience: NFC transactions happen faster than scanning QR codes. Just a quick tap and you’re set. With QR codes, you need to get the code in the camera's view.
• Security: NFCs are considered secure due to the short-range nature of communication, reducing the risk of unauthorized access. Additionally, encryption protocols can be employed to protect data. Meanwhile, QR codes can be susceptible to tampering or malicious alterations. If a QR code is replaced or redirected, users might unknowingly access fraudulent content.

While QR codes offer simplicity and widespread use for fixed information like web links, NFC introduces a touch of magic with its flexibility. Its ability to facilitate dynamic interactions and support a range of use cases makes it suitable for advanced applications.

In essence, NFC technology opens doors to a world of possibilities, making our interactions with devices, information, and the environment more intuitive and magical. As technology continues to evolve, we can expect even more enchanting applications of NFC in our daily lives.
