Visa prepaid credit card - translation

Can someone translate this page?
http://vpc.lifecard.co.jp/

I'm mainly wonder:
-do you have to register these cards or can I use it immediately?
-does the unused value decrease every month?
-what amounts are these cards sold in? I only need it to pay for Amazon Prime.

It's a "prepaid" card, not a credit card.

- You have to create your account online with V PRECA.
- If you don't use it for over three months, they deduct 125 yen as account maintenance fee. (Upon initial purchase, there is a 200 yen purchase fee.)
- They come in 3,000, 5,000, or 10,000 yen. Valid for one year, you cannot top up the amount.

Thanks AK. I understand that this card is prepaid, but it can be used wherever VISA is accepted right?

Hi i kept researching bout this vprea and i have an issue code but its not working., i used a mix of hiragana and number and alphabets and its still not working., my dad in japan just sent me the issue code how do i type it in?

"Alphabets need to be in single byte, capital letter
Numbers need to be in single byte
Hiragana need to be double byte"

...is what I see on their website FAQ.
