The 3DS app Pokémon Bank accumulates Poké Miles over the duration of time that a Pokémon is stored on the Bank itself.
The player can choose to send Poké Miles or Battle Points to a chosen Gen VI or Gen VII game.
Since Gen VII games do not use Poké Miles, players are only able to send Battle Points to the selected games,
with the conversion rate of 1 Battle Point for every 10 Poké Miles.
While the card upload only has 10 Battle Points, it is possible to receive other amounts from Pokémon Bank.
