some questions for google wallet

[MrProph]

is there a way to change if you have a card saved for top ups?

im already skeptical about saving a card on there so whats the security measures when entering a pin after 3 times does it shut down and email you or something?

This might answer you, I recently used GW and it's been great! I figured out how to get my receipts by doing a screenshot then emailing to my work email for my expense reports.
