Re: Linking American credit cards to Wechat in China
Nowadays we can pretty much forget about using Discover at UnionPay merchants if you have a chip Discover card. The issue appears to be the POS doesn't recognize Discover's chip (maybe the terminals aren't upgraded to include Discover's AID). It was possible to get the transaction go through if you first insert the card and then fall back to magnetic stripe, but since fallback is no longer allowed you would have to use the chip and the card just won't work. If your card is magnetic stripe only, it should still work in most of the places. Most of the time you can simply hit Enter when asking you for a password.
