This page covers advantages and disadvantages of NFC. It mentions NFC advantages or benefits and NFC disadvantages or drawbacks.It also describes NFC basics.
What is NFC?
Introduction:
The term NFC is the short form of Near Field Communication.As the name suggests it is used for short distance data communicationbetween two devices known as initiator (i.e. NFC reader)and target (i.e. NFC Tag).
NFC finds various applications such as data communication between smartphones,verification of authorized persons at offices and other government places,ticket booking etc.
It operates at 13.56 MHz frequency with different low data rates viz.106, 212 or 424 kbps. The NFC tag can be active or passive and NFC reader is alwaysin active mode.
The NFC devices operate in half duplex mode and hence one device transmits the other receives.This is known as "Listen before talk".Refer NFC tutorial >>.
Benefits or advantages of NFC
Following are the benefits or advantages of NFC:
➨It is very convenient to perform payments and other trasactions usingsmartphones with the help of wallet app.
➨It is used for multiple applications in various domains such asbanking, reservations, booking tickets, redeeming, entry/exit passes etc.
➨It helps both customers and enterprises.
➨It provides secured access for students and employees in their premises.
➨It provides more security compare to magnetic strip based debit and credit cards.It also uses PIN.
➨It does not require search and pair procedure like bluetooth and other methods toestablish connectivity.
➨No special software is needed. Moreover it does not require manual configurations and settings.
➨It is compatible with existing RFID networks.
Drawbacks or disadvantages of NFC
Following are the disadvantages of NFC:
➨It can only works in shorter distances which is about 10-20 cm.
➨It offers very low data transfer rates which is about 106 or 212 or 424 Kbps.
➨It is very expensive for the companies to adopt the NFC enabled devices.
➨It is not so advantageous for users due to complex procedures compare to other easyoptions.
➨Though it is more secure compare to credit/debit card based system,it is not completely risk free. This is due to the fact that mobile based hacking is common now-a-daysdue to availability of most advanced tools and techniques which provides complete access of smart devices.
➨The power consumption is comparatively more in NFC enabled devices.

NFC Basics: NFC, or Near Field Communication, is a short-distance wireless communication technology designed for data exchange between two devices—an initiator (NFC reader) and a target (NFC tag). Operating at a frequency of 13.56 MHz, NFC facilitates various applications, including data communication between smartphones, access verification, ticket booking, and more. It employs different low data rates, such as 106, 212, or 424 kbps.
Advantages of NFC:
- Convenience in Payments: NFC enables seamless payments and transactions using smartphones through wallet apps.
- Versatility in Applications: It finds applications in diverse domains, including banking, reservations, ticket booking, and entry/exit passes.
- Beneficial for Customers and Enterprises: NFC benefits both customers and enterprises alike.
- Secured Access: Provides secured access for students and employees within premises.
- Enhanced Security: Offers greater security compared to magnetic strip-based debit and credit cards, incorporating the use of PIN.
- Ease of Connectivity: Unlike Bluetooth and other methods, NFC doesn't require a search and pair procedure, making connectivity straightforward.
- No Special Software or Configurations: NFC is compatible with existing RFID networks and doesn't require special software or manual configurations.
Disadvantages of NFC:
- Limited Range: NFC operates in shorter distances, typically about 10-20 cm.
- Low Data Transfer Rates: It offers relatively low data transfer rates, ranging from 106 to 424 Kbps.
- High Cost for Adoption: Companies may find it expensive to adopt NFC-enabled devices.
- Complex Procedures: The technology may involve complex procedures compared to other, more user-friendly options.
- Security Risks: While more secure than traditional card systems, NFC is not entirely risk-free due to the prevalence of mobile-based hacking tools and techniques.
- Power Consumption: NFC-enabled devices tend to have comparatively higher power consumption.
