Mmm are you talking about the Suica cards?

When i use JR i jus buy a Suica card, which can also be used at some of the shops and vending carts and Vending machines.
You pay 1k Yen and you get 1k Yen of credit on this plastic card.

Instead of putting a Ticket into the booth you just put the card in your wallet and wave it above the sensor thing and it lets you thru, works the same with the Vending machines and shops.

When you run out you can jus put the card back into the machine and add more credit.

This is good if you dont know the price of the ticket in where you want to go to.
So instead of underpaying or overpaying *which is both annoying*
you jus get the exactly amount subtracted from your card.

Most rail lines have these cards.

n e prob just pm me
