I just returned from Hong Kong. For my first purchase, I used my UnionPay card to test things out by buying train tickets on the Airport Express Line to Hong Kong Station:



Of course, there was no DCC even though their acquirer, Citibank, offers it on Visa and MasterCard. The purchase amount was HK$170.00, and the posted transaction amount was $21.97. This is slightly less favorable than what the Visa rate would have been using my Chase Sapphire Reserve at $21.91. In absolute terms, it's not too bad and definitely better than getting hit with DCC. From reading some posts on FlyerTalk, UnionPay's exchange rates are slightly higher than Visa/MC, but nothing too egregious. On average you'll see a charge post about 0.25-0.50% higher than what it would have been with Visa or MC.

I also tested the QuickPass at both Market Place by Jasons and Mannings with percysmith, but we couldn't get it to work. We did, however, have a successful transaction with my Chase Sapphire Reserve via Android Pay at Jasons.

Overall, I'm happy that this card works as advertised, and I think it will serve me well for any future travels to Mainland China. I don't necessarily know if I'd make it my everyday spend card, but it's certainly helpful in those places where I'd be making a small purchase, don't want to deal with cash, and don't want an issue with DCC. Also, the widespread acceptance helps quite a bit. I think I will still use my Chase Sapphire Reserve for larger purchases and any shopping categories with bonuses.

Also, I edited out 6 digits of the card number that appeared on the receipt, indicated with the lines under the Xs
