Here's how to resolve any payment issues you may be having: Carefully double-check your payment information (credit card or debit card) and its expiration date. Make sure your bank account has adequate funds in it. Possible reasons why you can't upgrade include not having enough money in your account or problems with the QRコードリーダー & バーコードリーダー site's payment mechanism. That's a dealbreaker, obviously, but don’t fret just yet. Wait a little while and then try again.
