The administrative unit where the credit card is used to fill in the professional position is:

Just fill in the name of your unit. If the unit has more than one name, be careful to match it on your business card or work certificate. If the company has a website, don't forget to write it at the back. If it is a listed company, write down the stock code and listing place.

Credit card usage skills:

1. Credit cards can also be used for online shopping.

Credit cards can also be used for online shopping or consumption. When you pay by credit card online, you will generally be required to provide the validity period of the credit card and the identification code on the back of the credit card to confirm your identity, and you will also use the mobile phone verification code to verify your identity. Of course, credit cards can't be recharged to Alipay or Tenpay, because credit card recharging is equivalent to cashing out, which is illegal.

2. There is no password for credit cards.

if the credit card has a password, you need to enter the password when you swipe your card. if you don't have a password, just sign it to confirm the consumption. Maybe you think it's not safe to set a password, but it's not right, because the merchant is obliged to check your signature. If someone else uses your signature to spend money, the responsibility is not on you, and the bank needs to compensate you for your losses. If you spend with a password and your credit card is stolen, the merchant is not responsible.
