A method and system for implementing debit card service based on callback. The method is applied to a mobile terminal set with an automatic dialing function unit, automatic dialing function of the automatic dialing function unit is activated, and a number corresponding to the mobile terminal is bound with one debit card. The method includes the following steps: a preset callback access number is dialed before the called number by the automatic dialing function unit in the mobile terminal to connect the call to a debit card service platform when the mobile terminal calls the called number; the debit card service platform releases the call and calls back the mobile terminal; the called number is continued by the debit card service platform after the mobile terminal answers the callback; the debit card service based on callback is implemented. The method and system can support two callback modes, based on the hardware and the software synchronously, to overcome the secondary charging problem in the debit card service and improve the user experience.
