@Kris, believe me, I am actually like you. I would hate to pack everything in my smartphone. Unlike other people, I often leave home without my phone, but I would not forget to bring my car key and house key!
I know Junko...and fully understand a desire to pack everything in one device...but centralizing everything in one device creates many potential problems in case of drain battery, hacking or just plain losing it...you probably need a backup phone stored in safe location, home?, safety deposit box?...personally I prefer to have my phone, my keys and my wallet as separate devices...but that could be an old fashion view, I recognize that...Kris
But you know, digital still cameras are quickly being replaced by smartphones; many use GPS in their smartphones while in their cars; and certainly, in some countries, transit cards are replaced by NFC inside smartphones.
It may not be the real "problem" as you say, but it could happen. Never say no to what people do these days with their smartphones!
I am both creator and consumer of smart electronics...but sometimes I wonder why people try to solve problems which are not real problems...don't we have enough real problems around? what is wrong with the standard car keys? that you misplace them? well, you can misplace your phone too? they will not discharge at least and nobody wil hackem them...Kris
@Rick, yeah, really. I was originally thinking about doing a story -- dissecting what Nissan Watch brings to drivers... I may still write about that, but aside from its cool looking design (I actuall like it!), why would you need to be "told" by a watch that you need to slow down? Seriously. It's like having your mother sitting next to you in a car, and telling you how to drive!
Thanks for your kind words, chanj. Just like you, I got very excited initially at an idea of a car keying being one more thing that could be replaced by a smartphone. Going through the thought process and talking to people was a lot of fun.
But as more and more people living in big cities start using a car sharing scheme like Zipcar (instead of owning a car), smartphone definitely has a role to play. It can be a paperless identification and payment device to gain an access to the car you are sharing. But of course, you still have to open a car with a physical key!
Technology is not the obstacle here. It has to be convenience and security.
You are so right about this. Then, the question becomes which is the best technology to get the job done, in order to achieve convenience and security. When NXP started making chips that incorporates "vehicle theft and smart access solution," I thought it was brilliant. Because your car key is not just a physical key to open and close the door of your car, but it is also an anti-theft device.
Now that many people already have a smartphone, putting a smart car key inside a phone seemed like solving the convenience issue -- having one less thing to carry around. But alas, for the moment, that technology choice turns out to be not so convenient. Is it more secure? I am not sure.
Besides the topics and issues you mention I can imagine one more aspect. Where to go to if you are not able to open the car door or start the engine? Is it the responsibility of the car manufacturer to solve the problem? The responsibility of the phone manufacturer? Or the responsibility of the carrier who provided you with a phone when you took a subscription?
