Open Jimmy Kimball on your mobile phone, log in to your account, and select my transaction after logging in. Enter my transaction and select "Bank Card" here. Enter the bank card management page and select "Unbind". Then enter the transaction password here, and then click OK to unbind the bank card. For so many internet financial fund babies now, if they don't use it, they should untie their bank cards.
