You can't use it for any type of streaming like Bluetooth or internet connections such as Wi-Fi. NFC is limited to short-range connections and can only handle small amounts of data. We also see some NFC use in smartwear to transmit basic information. Smart devices, like smart locks, can be controlled more securely than Bluetooth. It saves time compared to something like a QR code. If you're unboxing a router, smart speaker, or other consumer devices for the first time, it's likely that you'll find instructions to use an NFC link to connect your phone and set up devices. While NFC doesn't have a lot of gaming applications, there's one big one: Nintendo's Amiibos, action figures that come with NFC technology that can link profiles and let gamers carry a little bit of their character information around. This helps track shipments accurately, with more capabilities than RFID, or Radio-Frequency Identification, identify stolen items, and more. Valuable or important items may include NFC tags so that they can be quickly scanned and identified. Phones may be able to share contact information, URLs, or other types of data with a simple tap or by passing phones near each other. You can find this technology at point-of-sale systems and also in public transportation and venues for authentication and payments.

Many credit or debit cards include NFC tags for similar benefits. You can swipe your phone to use Google Pay or Apple Pay, for example, as enabled by Square and a variety of other transaction brands.
