2. UnionPay card VS other identification cards: Using bank cards in consumption abroad is also the most economical and safe payment method. At present, tourists can save about 1.5%-2% of the currency conversion fee by swiping UnionPay cards abroad. Take consumption in Japan as an example. If you use UnionPay card or spend money through UnionPay channel, UnionPay will deduct RMB from your account according to the exchange rate of RMB against Japanese yen on that day. If you use other cards to pay, the consumption must be converted into US dollars first, plus a currency conversion fee of about 1.5%-2%, and then converted into RMB according to the exchange rate of US dollars against RMB. In this way, the same credit card consumption is 6.5438+0 million yen, and using UnionPay cards or choosing UnionPay channels can save tens of RMB.
