Ignite Presentation: Near Field Communication

Near Field Communication (NFC) is a set of standards that allows smartphones and similar devices to communicate wirelessly by bringing them close together, typically within a few centimeters. NFC operates on Radio Frequency Identification (RFID) principles, enabling devices to transfer data in both active and passive modes. While NFC is not new, it is often misunderstood, especially when compared to Bluetooth. This guide explores NFC's functionality, security in contactless payments, social networking, and addresses common questions about NFC capability in phones.

  1. Ignite Presentation: Near Field Communication Harry Yang

  2. What is NFC? • Near Field Communication, or NFC, is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters.

  3. How Does it Work?

  4. How Does it Really Work? • NFC is based on Radio Frequency Identification (RFID) standards, meaning that the chips work by generating their own RF fields. In Active mode, this means both devices are generating fields for file transfers. In Passive mode, one device, called the “reader”, generates the field, while the other, the “tag”, recognizes the signal and becomes enabled.
