Hello! Thanks for using our company's products! The latest version of our company's FC-1882M supports external card readers, when you purchase, please consult the salesperson to see if the access controller is the latest version.

When connecting the card reader, you need to connect a single-head PH2.0mm-2p terminal line, and then connect to the white terminal WD IN (2P white small socket) of FC-1882M.
