The money in the salary card bears interest according to the current deposit, and the interest rate is extremely low. The bank counts the balance on the card every day, multiplies it by interest, and settles the interest on a daily basis. I suggest you buy some money or bond funds according to your monthly balance, which has low risk and stable income. After a year, it will be much more valuable than putting money in your salary card. You can also run a deposit and withdrawal business in the bank, with a little more interest, but not as good as the fund mentioned above.
