Limitations of NFC
Though NFC has got its own advantages, there are a few cons of the technology. It is important to know the limitations too. They are as follows.
- Shorter Range: The range in which NFC could be used to communicate is very short. Hence requires both devices to be very near for the transaction or the communication to be successful.
- Expensive: It is relatively expensive for small businesses or companies to afford NFC-Enabled devices.
- Data transfer rates: It would be best option for lesser data transfer rates. It is because NFC can offer only data transfer rate which is about 106 or 212 or 424 Kbps.
- Fradulent: NFC can lack security at times and leave way for fraudulent activities.
- Phone glitches: It requires the phone to be unlocked until the data exchange is done. If the smart phone automatically locks, then then NFC won’t work.
Everything You Need to Know About NFC
Communication and data transmission play a vital role in today’s digital era. It makes the transmission of information possible from one device to another and from one place to another. With a large amount being stored and transmitted every day, it requires proper communication protocols. Communication has been evolving constantly. We’ve come a long way from using messengers to wired communications and then to wireless modes. Yet, we still keep advancing in various wireless methods of communication. Wireless communication is the transfer of data eliminating the use of wires and cables. The different types of wireless communications include satellite communication, infrared communication, broadcast radio, microwave communication, Bluetooth technology, etc. One such advanced technique is the Near Field Communication or NFC. NFC is used for the transmission of data using radio waves especially, for shorter distances.
