In order to keep the movement at my wife's parents house, I rented a car at the airport and used it as a means of transportation.

However, every time I borrowed a car, my sensitivity gave me a hard time refusing things called "smart keys".

A "smart key" is a function that allows an automobile to recognize a person, who owns the key as an "owner". It enables the owner to allow anything (unlock / lock / engine Start) without the ordinal key's operation.

The "smart key" gives us easy operations about cars.

Firstly I thought if I was robbed of this "smart key" by another person, it means "I was robbed of the car itself". however, I noticed that it was same even if I use the ordinal key.

When I think that carefully, nothing has changed anything else, because "the owner of the key is equal to the owner of the car," and we have manage the cars.

Rather, unlike ordinary keys, a "smart key" can not be easily duplicated, so t fear of theft has drastically decreased.

Whatever I think, a "smart key" is basically winner more than the ordinal key.

However, it cannot be helped about "uncomfortable feeling".

So, perhaps, persons who does not use personal computer, smartphone or e-mail, I think that there is "uncomfortable feeling"

And, the elders who used the conventional system, feel "uncomfortable" on a large scale.

In other words, elderly people are not only because they are elder,

but also it took a long time to use a conventional system. Therefore it is difficult to change to a new system

I thought that it would be that.

A person (I) who feel uncomfortable with "smart key"

cannot criticize the persons who do not use "email".

I also think "it is ridiculous".
