this payment method is generally called non-magnetic and non-secret payment (it can also be called non-card and non-secret payment), and its characteristic is that only the cardholder needs to provide his name, card number, expiration date and CVV2 to complete the payment, whether online payment or telephone payment, as long as the payee has this information, the payment can be completed. This payment method is a mainstream payment method abroad, which is characterized by convenience, but the same disadvantage is also very prominent, that is, the risk of credit card theft is high.
for this kind of payment, the bank will state that if there is any problem, the merchant will bear all the risks. The goal pursued by Amazon is customer satisfaction, and the company's philosophy is that customer satisfaction is paramount, so it is willing to bear the loss in this respect in exchange for a faster payment experience for users. But I still have to protect my account to avoid credit card information leakage.
