Introduction

NFC communication by itself doesn't provide us with many features due to its small data transfer characteristics. For instance, we can only exchange small data packages between devices, and tag sizes are also (very) small. In this chapter, we will see how NFC can be used to enable adapters such as Bluetooth so that we can take advantage of NFC characteristics while still being able to create more complex apps.
