It can rotate. You mean to transfer Huai 'an card to Suzhou card? You can handle it at Atm or at the counter. The handling fee is 1%, with a maximum of 50.

If, as they said, you are in Suzhou, I suggest you open a Suzhou card, and by the way, open an online banking in Huai 'an (which can be handled in different places), so that if the money in Huai 'an card is transferred to Suzhou card, the handling fee can be 10% off.
