China is almost credit card free now, except for things like pre-auth at hotels. People use apps like alipay or wechat to pay everything. They have the following advantages: * Easy to use, you always carry your phone. * Never expire. * Password protected, card number and CVV are fragile. * Works without a POS. Basically in China QR-codes on paper are everywhere. * Online payment is super easy, you won't need to type billing addresses, etc.
