Is it necessary to open online banking and SMS notification for workers to apply for salary cards? Is it reasonable for banks to do so?

I don't know if your online banking has been done. You don't need to do online banking for salary cards. Online banking is risky. If you handle it, you must take good care of the password card, otherwise the security cannot be guaranteed. Once someone understands online banking, it is easy to steal other people's money. And it came without a trace, and there was no way to find it. Remember to remind everyone to keep the password and password card and the card.
