The card reader includes a PCBA having four standard USB metal contact pads and several extended purpose contact pads disposed on an upper side, components and IC chips covered by a molded case on a lower side, a molded lead-frame connector mounted on the PCBA and including five forward-facing extended purpose pins and eight rear-facing micro-SD connector pins that communicate with the PCBA through the extended purpose contact pads, and a housing including a slot for receiving a micro-SD card such that it communicates with the PCBA through the micro-SD connector pins. The extended 9-pin USB socket includes standard USB contacts and extended use contacts that communicate with the PCBA through the standard USB metal contacts and forward-facing extended purpose pins. The PCBA includes dual-personality electronics for SD/USB communications.
