The validity information of a credit card is very important for activation and use. Usually, this information will appear with the sign "VALIDTHRU", which indicates the expiration date of the credit card. For example, "7/2" means that your credit card will expire in July 22, and the date format is month/year.

there are many ways to activate a credit card. First of all, by phone activation, just pay attention to the four digits of the validity period, such as "5/18", and directly type 518 when entering. Secondly, if you choose to activate through online banking, the input method of the validity period should be consistent with the format on the card face, and you only need to input these four numbers. Finally, if you choose to go to the bank counter for activation, you need to provide the expiration date in the same way to ensure that you provide accurate four digits.

in short, whether it's telephone, online banking or counter activation, the valid period of credit card is entered in the form of four digits, and it should be presented in the format of month/year. Ensure the correct input to activate and maintain the effective use of the credit card smoothly.
