How does NFC work?
NFC vs Bluetooth: NFC stands for Near Field Communication and it’s a way for your phone to interact with something nearby. When held nearby, NFC allows smartphones and other devices to communicate via radio signals. This allows for two-way communication, with both devices sending and receiving information. NFC technology establishes a short-range network to exchange data using electromagnetic radio fields. NFC tags can be both read and written; they contain between 96 and 4,096 bytes of storage depending on the type of tag. This requires at least one transmitting device and another to receive the signal — a phone is often used as the signal receiver.
What is NFC used for?
NFC, which is short for near-field communication, is a technology that allows devices like phones and smartwatches to exchange small bits of data with other devices and read NFC-equipped cards over relatively short distances. NFC can be used for mobile payments, such as with Apple Pay, Google Pay, or Samsung Pay. However, NFC can do a lot more than just handle mobile payments. For instance, NFC can also be used to store digital keys that can unlock everything from your front door to your hotel room.
What are the advantages of NFC over Bluetooth? NFC Vs Bluetooth
One advantage of NFC over Bluetooth is that it consumes less power than Bluetooth, so even if you leave it on, your battery won’t be drained faster. Another advantage is that file sharing with NFC doesn’t need pairing, which makes it quick. NFC can also be used with NFC tags – you don’t get this with Bluetooth. Payments are safer over NFC and Bluetooth actually doesn’t have functionality for the protection of sensitive data like bank details.

What are the disadvantages of NFC?
One disadvantage of NFC is that it is not as effective and efficient as Bluetooth or Wi-Fi Direct when it comes to data transfer rates. NFC can only send and receive very small packets of data. Another disadvantage is that NFC technology may be too expensive for some companies, as it usually involves a suite of related devices, equipment, and upgrade-dependent standards.
Is NFC faster than Bluetooth for data transfer? NFC Vs Bluetooth
No, NFC’s data transfer rate is slower than Bluetooth, with a typical data rate of 424 kbit/s. Bluetooth has a maximum data rate transfer of 1-4 Mbit/s. So, Bluetooth sends data more quickly than NFC.
What is the range of NFC?
NFC has a maximum range of around 10 centimeters.
