Can Alipay check the salary?

You can't check directly, you can check indirectly.

You can give a chestnut: you put the balance of the bound salary card on Alipay, and then short your card. If you want to know whether Chakkari's money has arrived, check it directly or indirectly. For example, your salary unit clearly gives you 5000 yuan, and you can transfer 4000-5000 yuan to Alipay account. If the transfer is successful, then the salary will arrive.
