My Discover card is on its way -- I hope it's finally a way to avoid DCC without having to use my Chinese debit card which gets no points.

My question - has anyone successfully linked their Discover card to a smartphone payment service such as Alipay or Wechat? This would be an ultimate coup for me... but it seems too good to be true as you can manufacture spend bigtime by using their money management products or by paying friends.

Edited to add: I have linked up my Chase Hyatt card to wechat, but can only top up my mobile credit with it.
