Google pay cards - copy from 4a to 5


New pixel 5 arrives today ( Pixel 6 will be too big ) and I need to copy my Google pay cards across to it.

I left my physical wallet at my brother's house and wont have access to the actual debit/credit cards til next week

So if I sync my debit card to my pixel5, can I use it to make payments or do I have to add the debit card by manually adding it to the pixel5 by scanning the card in the Google pay app ?
