At present, the main forms of credit card bills are paper bills, electronic bills and MMS bills (most banks have closed this service). Paper bills and electronic bills have their own advantages and disadvantages. Not all banks use electronic bills, so some older cardholders don't use email. They usually use paper bills.

The difference between electronic bills and paper bills lies in convenience, environmental protection, audit and guarantee.

Convenience: the mailing address of the paper bill is the company or home address filled in your application form. When you change companies or are not at home, you may delay the repayment time because you can't receive letters in time. Moreover, the electronic bill can be viewed on the mobile phone anytime and anywhere, and it will also remind customers of the time and amount of repayment, which is very convenient and fast.

Environmental protection: It takes a lot of wood to send paper bills every month. Choosing to let the bank send you an electronic bill every month can reduce hundreds of millions of trees on the earth in one year.

Audit: Many cardholders want to see the consumption situation for half a year or a year every six months or the end of the year. If it is a paper bill, it is easy to lose it, while the electronic bill is stored in the mail every month, which is convenient for cardholders to check the previous bills and consumption details at any time.

Security: Because the paper bill has a written deposit, it can provide more reliable evidence in controversial transactions, and the cardholder is more at ease.
