UOB ONE CC: $500 eligible spend? 1. If I link my uob one card on Apple Pay and use it for public transport, does this contribute to the $500? 2. I generally eat at places that accept cash only.

You might like to look out for stalls with QR codes (even with those that accept cash as it is quite the norm

now) that you can scan and pay with your UOB card ...

1. Yes, spending on UOB One card via Apple Pay counts towards your minimum spend, so long as the transaction is an eligible spend, e.g. public transport (simplygo).
2. Since the place accepts cash only, then you have to pay cash. As a result, I'm not sure how you would want to use a credit card. Maybe I got your question wrongly - please clarify.
