The present invention provides a method for reducing RF interference inside a dual-interface card reader and a dual-interface card reader, which relate to dual-interface card reader field. The method includes: adjusting RF power by the dual-interface card reader to reach a specified maximum value; determining the type of an IC card which is operating currently by the dual-interface card reader; if the IC card is a contactless IC card, responding to the contactless card and not responding to any contact IC card before the operation of the contactless IC card is completed by the dual-interface card reader; if the IC card is a contact IC card, adjusting the RF power so as to make the RF power to be lower and responding to the contact IC card by the dual-interface card reader, and if a contactless IC is operating before the operation of the contact IC card is completed, responding to the contactless IC card simultaneously by the dual-interface card reader. The dual-interface card reader includes: a determining module, a control module, a contact card communication module, a contactless card communication module and a data transferring module. The invention provides a solution for reducing RF interference inside a dual-interface card reader, which is implemented easily and conveniently. The identification effect of the dual-interface card reader is improved.
