I would also pretty much like to have a "invoice" / confirmation email for:

Membership activation / continuation / cancellation (when it does not automatically renews anymore) notice When Coins are purchased that includes: how much coins are purchased, for how much each coins was purchased (based on membership), and total cost When Coins are spent, to receive confirmation that a coin was actually spent and to have a general confirmation, this email should include: how many coins are spent (1 in most cases), which title it was, plus a download link (or where to download it, even if it is just https://j-novel.club/user/library)

Also, the current email that is sent out for coins purchased is just not enough, also i dont think a email like admin@j-novel.club should be used, but (like other services do it) noreply@j-novel.club or confirmation@j-novel.club

PS: it would also be nice if these email would be structured like invoice emails to be automatically displayed in something like gmail (like steam does it)

@fozzedout And people scoffed at me.

No but seriously the "restrictions" I have put in place are very much to attempt to change people's market behavior to something that grows light novels in general as a reading market.

I don't want people to buy more books, exactly, what I want is people to be given more incentive to buy more books more often.

Taking any information beyond the card number, its expiration date, and the security code on the back is optional.
It can be used in the verification process but it doesn't need to be. Basically, taking more info makes it more annoying for the user (have to type more info in, give up more personal information), but helps reduce credit card fraud for us, J-Novel Club. Every bank/credit card issuing company can have their own standards and systems about which charges to approve/disapprove. However this is the first time I've heard of one that actually required an address?
I have heard of ones that will block any internet transactions by default for brand new cards or cards issued to students, etc.

So in any case, we don't take that extra info because we don't need it to sell you what we are offering, and in 99% of cases it doesn't affect anyone's credit card processing. I'm not sure about the specific card you are attempting to use, but that's really up to the policies of your bank.
