Divided into two cases:

The first: not add a bank card:

WeChat receives payments or receives accounts, even if you do not have a bank card bound, it is also possible to use. It's just that the limit is a bit more.

When you don't add a bank card, you can also use change to transfer money. But your micro-signal is limited to a single transfer amount of 200 yuan per day, and 3,000 yuan per day for the recipient.

The second type: added a bank card

After binding a bank card your transfer amount will increase, but the same is limited. This time you can not only use your change to make transfers, you can also use your own bound bank card to make transfers. The limit is 50,000 yuan for a single transaction in a single day, and there is no limit to the recipient.

There are no fees for the transfer function at the moment, but if you want to withdraw your change to your bank card, you'll need to pay a fee. But this fee is not charged by WeChat, but you need to pay the fee to the bank.
