Near Field Communication in your phone

Posted 03 November 2010 - 08:53 AM

So i was reading about a hotel that is switching to using Near Field Communication instead of room keys. I think that this technology will go along way in how consumers interact. I think that once this gathers more steam we'll see more and more retailers putting in "speed pass" type stations where all you have to do is wave your phone near the register and it automatically pays for transactions. It'd be more secure then carrying around bank, and credit cards because it can be disabled and enabled within seconds, so if you loose your phone you can have it disabled, and when you find it you can then have it reenabled.

Is This A Good Question/Topic? 0

It doesn't take much to build a reader into a PDA in your front. Stand in line at the store and read all of those RF transmitting cards, fobs, passports and so on in the back pocket wallet of the guy in front of you. So they really aren't all that secure.

There was a case not that long ago where someone left just such a device wrapped as a store decoration xmas package at the sales counter. The staff all thought it was there for theming. In reality there was a reader transmitting back everyone's cards as they were paying for their purchases.

from what i understand you can set up your phone at least to require a password before data is transmitted. This at least allows for better security then straight RFID one way style.

A WiFi router can have a username and password setup on it also.
But there are 3 in my neighboorhood that have an SSID of "linksys" with the factory username and password and settings.
I could use any of them for my internet if I wanted. Just because a device can have the option, the typical user isn't aware or proficient. Just look at half the questions in technical forums by so called pros and you can see that many people who are in the field are very under-educated for the task.

You can also say that Credit Cards and Debit Cards are just as unsecured. People put devices in card readers in gas pumps, and other card reading devices to collect and transmit the data on your magnetic strip. There is also the pick pocket that steals your wallet. The reason why I think NFC would be a better option for security is because not only does it allow for the user to setup a password, but it also requires that a reader be within 5 cm of the phone, or card. This means that the person trying to read your device would have to be so uncomfortably close to you that you'd notice, or they would have to do the same to the device. In either instance you should be aware. This is a much shorter range then RFID methods. NFC is used all over the world for various types of payments, including 7-eleven in Dallas, TX.

Also the SDK supports several languages so it is portable. It is also Open source.

A pick pocket takes your wallet. As soon as you know it is gone you call and cancel your cards before a charge can be made.
A PDA with reader just copies it without you ever knowing until the charges are made.

And a pick pocket even closer... in physical contact even. You'd notice that. And still it happens.

With NFC/RFID you can pick pocket without taking anything... leaving the mark unaware. Same tricks, same techniques without getting caught at the time. Bump into someone on a crowded subway train or bus... walk through a crowded casino on New Year's Eve... slide past the row of people in the stands at a baseball game or concert... All of these put you uncomfortably close to someone else for a few seconds. If the mark is worried and checks to see if you took his wallet he shrugs and says to himself "Nope, I still have it" and feels safe.

You do as you like. I'll continue to pay through direct physical means of either reading a magstripe on a card or ...gasp... CASH.
