Are Smart Phones and Tablets Better Off Without NFC?

At one point or another, we have heard about NFC as a new feature in smart phones. So, what is it?

NFC or Near Field Communication is a relatively new feature in electronic devices that simplifies data transfer, operation and communication. It is “near field” because it only needs a few centimeters or less in order to pair up with another device. But Bluetooth and WiFi can also do this, right? What’s the difference?

The answer is speed.

With NFC, all the user has to do is simply tap one device to the other and they get connected automatically. There are no more waiting and codes to be entered, except in instances that require a PIN, like in the case of making payments.

Because major telecommunications, semiconductor and computer companies along with banking institutions are NFC forum members, we can expect a wide array of applications for NFC to be incorporated in their products. Some of the fields being tapped as of now include social networking (file sharing and gaming), e-commerce (mobile payments and electronic money) and security (electronic keys and ID’s).

Is NFC secure or reliable?

Unfortunately, NO.

NFC devices produce signals that can be picked up by other devices as well. The transmitted data can then be manipulated and modified. An unknowing user might be subject to attack without even knowing about it.

Furthermore, an NFC device is capable of storing almost all of the vital information about the user. Have you ever lost a bag with all your ATM’s, keys, credit cards and ID’s in it? Remember the hassle that you have to go through? It is much the same. Only this time, it is not a bag but a mobile phone or a tablet.

Should NFC in devices be ditched?

NO.

It is better that devices like mobile phones have it in case there is a need to  use it. NFC will make transactions simpler but it must have added security features. Manufacturers must be able to make users comfortable when using it. And companies must have good answers when asked, “What if my phone gets stolen or lost?”
