Introduction

NFC is a short-range wireless communication technology that allows the exchange of data between devices over a distance of less than 10 cm. It's based on radio frequency identification (RFID) technology and operates at a frequency of 13.56 MHz.

NFC technology is widely used for contactless payment systems, access control, and data exchange between two devices. With its increasing popularity, many web developers are exploring how they can use NFC technology to enhance their websites and applications.

In this tutorial, we will guide you through the process of writing a website to an NFC card and introduce you to the types of applications and tools you can use to get started.

What You'll Need:

  • An NFC-enabled smartphone or tablet
  • An NFC card
  • An NFC reading/writing device
  • An NFC writing app (e.g. NFC Tools, NXP TagWriter, etc.)

Step 1: Obtain an NFC Card

There are different types of NFC cards available on the market, including passive (powered by the reader) and active (powered by a battery). For the purposes of this tutorial, we recommend using a passive NFC card, as they are widely available and easy to use.

You can purchase NFC cards from various online retailers, such as Amazon or eBay. Be sure to choose a card that is compatible with your NFC reading/writing device.
