You can see me if you get out more

Question

I contain some very important information.

You likely display me all the time.

But if you were asked to name my contents,

You might not remember - perhaps -

And you'd likely be in a bad spot and not be able to recall.

Some places folks have two of me, some places folks have one.

In some seedy places I often don't exist,

But if you've got lots of money, you've got lots of the thing -

The thing that needs ME stuck on its back.

Getting me can be a pain; the lines are often long.

(At least in the U.S., this should be a dead giveaway).

All the same, though you see me every day,

and you use me every day (indirectly)

You probably don't think about me much

at all.

Who am I?

Answer 1

Answer:

License plate

I contain some very important information.

The license details for the car

You likely display me all the time.

It's fixed to the outside of the car whether you are using it or not.

But if you were asked to name my contents,

You might not remember - perhaps -

People are a bit rubbish at remembering the license plate contents

And you'd likely be in a bad spot and not be able to recall.

Some places folks have two of me, some places folks have one.

Some locales have them on the front as well as the rear.

In some seedy places I often don't exist,

Dodgy people might remove plates or not have them in the first place

But if you've got lots of money, you've got lots of the thing -

The thing that needs ME stuck on its back.

Cars, cars are expensive

Getting me can be a pain; the lines are often long.

(At least in the U.S., this should be a dead giveaway).

The lines at the DMV are legendary

All the same, though you see me every day,

You'll see them on your own car and others every day

and you use me every day (indirectly)

By using the car you are using the license plate

You probably don't think about me much

at all.

Answer 2

You are an

iphone!

The thing that needs ME stuck on its back

I assume that is the Apple company logo on the back of the phone. The iphone is Apple's main income source (as far as I know) thus Apple needed their iphones to succeed.

Getting me can be a pain; the lines are often long.

(At least in the U.S., this should be a dead giveaway)

I thought at first that you are a pc screen before those two lines.

Edit - my explanation:

People hold their most important info, such as phone numbers, messages, photos and music on their smartphones. They are frequently holding them out at public, thus displaying them to everyone. People are usually interested in the specs of their phones only at purchase, and then gradually forget them. There are people with more than one phone, and under "seedy places" I assume poor countries or maybe off-grid farms there technology is not very popular/ available.
