(Continuation from yesterday)

And now suddenly, I noticed

"I just give the driver the location information transmitter I made"

To put it simply, "I need to give a part of my system (location information transmission device)".

If this is the case, I know the driver's location information, and the driver does not have to worry about smartphone operation or security. Moreover,

"It is only me who can benefit from the device."

The point that "I have no attitude to share profits" is just like me.

There is a troublesome problem of cyber attack, because we want to use a publicly exposed server called the cloud.

Using 3G / 4G, which communicates directly with the device, can solve this problem.

I would like to think a little more about this device.

Let's stop the effort make them use a smartphone, if they cannot use a smartphone.

Both a person who can or cannot use a smarthone will be unhappy.

For those who can't use smartphones, just pass the device and become a "tool" that is convenient for us.

Just becoming a "tool" is enough to contribute to this smartphone society.
