I purchased the ENNEAD AR collecting cards (a set of 30) from Japan

Since BNOW is not available for Android users in Japan as of now, I have a few questions.

1. If I activate the cards on my iPad now, and change to a Galaxy or Android mobile phone after the BNOW app becomes available in Japan, will l be able to play with the AR cards using Bnow on my new Android mobile phone?

If yes, how do I do it?

2. Similar question: If I gift the card to someone after I used the activation code once, can I deactivate my account and let the gift recipient use the activation code on Bnow and play with the cards?

If yes, what are the procedures?

Thank you for your help in advance.

Best regards
