Animate point card has very complicated system.
This card has 2 system of points.
This point count up to purchase 1yen = 1point.
Every 10,000 point to saved, you can use card to discount 500Yen.
This point count up to purchase 50,000yen = 1point.
Every 1 point to saved, you can use card to barter to "Point Items".
In short, Animate card are able to 5% discount and prize to offering XD
For example, If you had been bought something purchase are just 50,000Yen, you got
1)Able to 2500Yen discount
2)5 Item Points
Do you have Animate's receipt? There are write in Japanese like below;
"現在値引可萩煌zは" 500円(or 1000円 or1500円...)
"値引可萩煌zまで あと" xxxxP
"景品交換ﾎﾟｲﾝﾄまで あと" xxxxxP
"今回発生ﾎﾟｲﾝﾄは" = You got Discount point today
"現在値引可萩煌zは" = Able to discount
"値引可萩煌zまで あと" = Remained for discount(up to 10,000)
"景品交換ﾎﾟｲﾝﾄまで あと" = Remained for Item Points(up to 50,000)
"景品交換できる点数は" = Saved your Item Points
