A bit of a niche data point, but I tried adding the card to Google Wallet and for whatever reason they put a fraud block on it. After calling in, they insisted I have to get a letter in the mail with a code to unblock the card. I had a trip coming up and intended to use the $300 hotel credit, but was worried that I would be unable to do so (the rep claimed it wouldn't go through).

I tried anyway and was pleasantly surprised to see that the booking worked, and I was able to utilize the credit.
