Only credit cards and cash can be used, and only your own credit card can be used.

Don’t use other people’s credit cards. Some of Ctrip’s free travel products to Hong Kong and Macau require the cardholder of the payment card to travel together. Please check carefully before booking.

If you have time, just apply for a credit card, it is very convenient. Or just use cash as a deposit. You will always exchange it for Hong Kong dollars anyway, so just change more.

Hong Kong hotels have different rules. In most hotels, even if you use a credit card to pre-authorize at check-in, you can only use the foreign currency channel. When checking out, cancel the foreign currency pre-authorization and then use the UnionPay channel to settle the bill.

Therefore, according to your situation, first of all, you cannot use your husband’s card, which is prohibited behavior abroad.

Even if you have a UnionPay debit card, the hotel may not be able to pre-authorize it when you check in.

To be on the safe side, you can call the hotel to inquire. No, you can only use cash.

RMB cash is also acceptable.

Using other people’s credit cards is illegal in Hong Kong and must not be done. You can use Hong Kong dollar cash to pay the deposit and settle the bill. Anyway, you need to prepare Hong Kong dollar cash for other purchases.
