The card password is 16 digits. Generally, two strings of numbers will be written on Jingdong's card, one is the card number, and the other is the card password.

Extended information

The Jingdong payment password is to ensure the security of funds in the Jingdong account. It is a password that needs to be verified when using coupons, Baitiao, Jingdou, Jingdong payment, Jingdong E-card, account balance and other services. This password is a combination of letters and numbers set by the user, or a 6-digit pure numeric password.

Therefore, when using Jingdong e-card, users should pay attention to distinguish between the card password and the payment password to prevent confusion. There will generally be prompts on the login interface and payment interface (how many passwords should be entered), and users only need to remember the corresponding passwords.
