Exchanging Data with Near-Field Communications

Hello Math 120! I hope everyone’s semester is going swimmingly. I found a great article on CIO.com and could not wait share it with everyone.

The article was titled “6 Cool Uses of Near-Field Communication”, but before I share some of the great insights from this article I wanted to explain a little about Near-Field Communication (NFC) in general.

Anyone that claims the radio is dead is far from right and NFC is a perfect example why radio technology is here to stay! NFC is a language that smart phones and other electronic devices can use to “speak” with each other via radio waves. The whole process is facilitated by bringing two NFC devices close together (less that one foot apart). Once the connection is established data exchanges and transactions can occur between the devices. The most exciting aspects of NFC are the the transaction that can be completed with unpowered devices called tags. These tags opened a plethora of opportunities for many industries to store and exchange information.

Now back to the article, CIO.com shared their top six most exciting uses and I would like to share the ones I found most interesting with you.

NFC Patient Tags

In the health care industry, a NFC technology called PatientID+. This initiative greatly reduces the pain and agony of having to provide extensive details about your entire medical history. Instead, this information is simply stored on an NFC enabled phone or on a NFC tag that an individual could simply wear. A legitimate concern relates to the sensitive medical information that you are “broadcasting” to everyone within one foot of you. This is why PatientID+ requires the receiver of the information to enter a PIN number to access the data, which is something only the patient should know.

This next one will hit home for anyone that has used the public transportation system. In Los Angles and Minneapolis public buses are now accepting NFC payments. Rather than having to keep track of transport tickets, bus riders now simply use an NFC enabled phone to provide the information to the bus service. This benefits the bus service as well as it greatly decreases many manual processes.

NFC with Parking Meters

One of my favorite applications of NFC relates to parking. Keeping enough quarters in the car and remembering how much time I have left in the meter can easily lead to many parking fines.An NFC technology called PayByPhone allows parking meters users to simply send money from their debit or credit card to the meter. Perhaps the most useful aspect of the technology is the text message later sent alerting the parking meter users of there soon to be expired meter.

Overall, NFC technology seems to be completely changing the way various entities communicate with one other. In seconds, large amounts of data can be exchange to provide information on everything from how much money to put into the parking meter to an extensive medical history. I hope that this area continues to grow as it will continue to shape our future.

Don’t forget the quiz!
