tour pass available for Alipay. change the Alipay app to international region (everything will be in English) or just search for "tourpass", topup using local Msia credit card, first time need to snap photo of china visa, and the balance would show up in the tourpass prepaid card. (balance not in Alipay wallet balance) - max RMB 2000
paying shud be the same like using alipay, option below the qr would be tourpass prepaid.
website claim any unuse credit will b credit back to the original credit card in 90 days.

personally had topup the tourpass, since goin to Hangzhou next week. very fast. Not sure the exchange rate, currently Bank of Shanghai, the bank which manage the tourpass is charging 0% til Dec 2019, so only pay for exchange rate by mastercard/ visa.

in the other thread ewallet in lowyat there are report ppl start using the tourpass, exactly as ez as alipay
