NFC, short for Near Field Communication, is a short range wireless RFID technology that makes use

of interacting electromagnetic radio fields instead of the typical direct radio transmissions used by

technologies such as Bluetooth. It is meant for applications where a physical touch, or close to it, is

required in order to maintain security. NFC is planned for use in mobilephones for, among other

things, payment, in conjunction with an electronic wallet, and for setting up connections

between Bluetooth devices (rendering the current manual Bluetooth pairing process obsolete).

Near Field Communication is sometimes referred to as “tap-to-print” or “touch-to-print” and provides

mobile devices the ability to directly print to NFC supported printers without connecting to the

network. New users of near field communication, especially for payment purposes such as storing

credit card information, are understandably concerned at first about the security and safety of their

private information. Possible security attacks include eavesdropping, data corruption or modification,

interception attacks, and physical thefts. Below we cover the risks and how NFC technology works to

prevent such security breaches from occurring.

Eavesdropping is when a criminal “listens in” on an NFC transaction. The criminal does not need to

pick up every single signal to gather private information. Two methods can prevent eavesdropping.

First there is the range of NFC itself. Since the devices must be fairly close to send signals, the

criminal has a limited range to work in for intercepting signals. Then there are secure channels. When

a secure channel is established, the information is encrypted and only an authorized device can

decode it. NFC users should ensure the companies they do business with use secure channels.

Data corruption and manipulation occur when a criminal manipulates the data being sent to a reader

or interferes with the data being sent so it is corrupted and useless when it arrives. To prevent this,

secure channels should be used for communication. Some NFC devices “listen” for data corruption

attacks and prevent them before they have a chance to get up and running.

Similar to data manipulation, interception attacks take this type of digital crime one step further. A

person acts as a middleman between two NFC devices and receives and alters the information as it

passes between them. This type of attack is difficult and less common. To prevent it, devices should be

in an active-passive pairing. This means one device receives info and the other sends it instead of

both devices receiving and passing information.

No amount of encryption can protect a consumer from a stolen phone. If a smartphone is stolen, the

thief could theoretically wave the phone over a card reader at a store to make a purchase. To avoid

this, smartphone owners should be diligent about keeping tight security on their phones. By installing

a password or other type of lock that appears when the smartphone screen is turned on, a thief may

not be able to figure out the password and thus cannot access sensitive information on the phone.

While it may seem like NFC would open up a world of new security risks, it may actually be safer

than a credit card. If a user loses her credit card, a criminal can read the card and find out the
