I guess even though the rates look different, the stuff smaller than the hundredth just doesn't do anything...
Yep, this was the process I was following the other day to reconcile the amounts. If you round to the nearest cent using the conversion rate for the date the transaction posted to your online activity and multiply by the foreign currency amount, you'll get an amount that matches the posted amount. It hasn't failed me yet. I just had another transaction post from Taiwan Mobile this evening (7/29 posting date). I did an online recharge of my account for 300 TWD x 0.033376 USD/TWD = 10.01 USD. The transaction posted for $10.01. ^
So at least when the unavoidable DCC transaction comes up with Chase, we can know how much we likely should have been charged.
