Everything You Need to Know About Near Field Communication

Dan Nosowitz 3/1/2011

Nososwitz’s article on Near Field Communication is both comprehensive and informative. He addresses the following aspects of this technology: What is NFC? What are its applications? Who are the stakeholders and why are they so interested? How big of an infrastructure change needs to take place? Is NFC safe? And finally, will this succeed?

He explains the technology in layman’s terms, stating that “NFC is a short-range, low power communications protocol between two devices”. One of the devices is the “initiator” and the other is the “target”. The initiator creates a radio-wave field using magnetic induction, which the target can detect and access, thus transferring data. This is all done within a 4-inch distance. It is very similar to RFID technology, only slightly more evolved. RFID readers like “E-Z Pass” are only one-way, sending information in one direction. NFC technology has the capability to send and receive information. The three main applications that NFC will be used for are; transactions, sharing of information and connecting to devices such as Wi-Fi routers or other phones. Purchases with NFC are an obvious application of this technology, however, we could potentially see the elimination of things like car keys, house keys, metro cards, ID’s and passports.

The current and potential stakeholders of NFC are very excited about these developments. Businesses, for instances, will be able to access your preferences and demographics in real-time and in turn create targeted ads specifically for you. Consumer benefits include not only convenience, but real-time coupons, promos and discounts.

According to this report the infrastructure in place with our current technology will be able to easily adjust to this new technology. Card reading technology is already prevalent in many businesses and mobile phone companies are already coming up with ideas to equip current phones with NFC capabilities. For instance, Blackberry is working on an NFC-enabled replacement battery door and iPhone users could potentially purchase phone covers with NFC chips inside them. We can expect to see NFC in the phones themselves in the near future, most likely in two generations of models.

One of the last issues addressed in this article is that of safety and security. I think this is a good starting point for our discussion on this aspect of NFC. Because NFC is transmitting your personal data and bank information, it of course comes with worries and questions.
