Security Aspects To Consider When Using Near Field Communication

Because NFC technology is a wireless form of communication, the potential for a breach of privacy and therefore, security is possible. Understanding the ways in which NFC information cold be acquired, corrupted or modified should be at the forefront of your use of this technology. Taking measures when possible to ensure that your customer's information is kept secure and communicating these measures to customers can allay their fears. This can improve customer loyalty and comfort with the use of NFC technology. The following are ways that have been identified as potential breaches of NFC communication security.

Eavesdropping, which is accomplished by an attacker's interruption of the RF waves that are exchanged in NFC technology, is perhaps the most prevalent threat to security. NFC communication is typically facilitated by bringing devices close to one another at a distance of 10 centimeters or less. Despite the fact that it would appear inherently difficult to intervene in communication that occurs at close proximity and in a matter of seconds, it can happen. Adept individuals have learned quickly how to circumvent the exchange of information in a NFC exchange and this can, theoretically, allow them to intercept the information while simultaneously allowing the transmission to occur. This provides an attacker with personal information and does so without any immediate indication of the breach.

Interception of an NFC exchange doesn't always translate into theft of information. In some cases, the attack is meant as a means to corrupt the information being exchanged, rendering it useless. This serves to impair the ability of your company to use NFC effectively and can be a costly annoyance. For your customers, an interception can be frustrating enough to encourage them to seek other companies with whom they will do business. This too, can eat at your bottom line and over time and with repeated interceptions, can deteriorate your reputation.

Another type of interception is known as data modification. In this kind of attack, the information being exchanged through NFC communication is captured and modified in some way by an attacker's RF device. The device inhibits the frequency of the NFC exchange briefly enough to alter the binary coding found within the data. This type of attack is not common, mainly because it is difficult to implement. In rare cases, an attacker can introduce their own information in place of that of your company, thus taking advantage of an NFC exchange for their own marketing exploits.

Because NFC technology is wireless, it can be difficult to implement measures to prevent every kind of potential attack. Encouraging the use of passive mode transmissions of NFC information can decrease the opportunities for attackers to eavesdrop. Data corruption can be prevented by introducing code in the NFC origination device that measures the strength of frequencies, thus choosing the one that is truly the closest and most likely, valid. Finally, when possible, using NFC technology that runs on a 106K Baud active mode transmission can significantly decrease and usually prevent any data modification attempts.


Near Field Communication: Uses For Contactless Technology Communication.
Near Field Communication technology is growing at a rapid pace, due in part to the rapid growth of mobile devices. While the uses for this technology certainly are limitless, there are specific ways that have been proven as effective. Depending on the type of product or service you offer however, you can also come up with new ways to use NFC technology that are as unique as your company.
