Why do parents receive information when they receive scholarships with their cards?

It may be that the phone number bound when handling the card is the parents'.

Generally, when granting state grants, parents will not be sent text messages unless the bank card account filled in is the parent's bank card account. When the bank card account amount arrives, you will send a text message to your parents' phone number, but if you fill in your bank card account number, you won't send a text message to your parents.
