thanks..As long as there are $$ of the country that you are spending on in the account, UOB will use that (either thru physical tapping of the debit card or purchase thru online, eg booking of hotels). The debit card is similar to the youtrip card. The con is the list of cuurencies available are limited. The advantage is that there's no validity (unlike youtrip) period. That is, you can keep the foriegn currencies on the account for as long as you want.
ok, so I am wondering if the rates are better than youtrip or trust or even amaze.I'm not sure whether it will auto use the main account if account is $0. But why do this? I tot it will be better that you exchange at a rate you desire rather than depending on the spot rate of the day. If you have spare after your holiday, you can always change back to SG (but I normally leave it since I know I will need it the following year). If you have insufficient amount, you can always log into UOB tmrw to buy the currency you want anytime.
