This is a PQI Air Card with Wi-Fi functionality. A 4GB Micro SD HC card is included as a bonus. - Brand: PQI - Model Name: PQI Air WiFi Card This card allows you to transfer data to your smartphone via Wi-Fi by inserting a microSD card and using the dedicated app. Please note that the camera needs to be turned ON when using it. It can also be used as an adapter to convert microSD cards to SD cards. Please use this with cameras that do not have built-in Wi-Fi. (Cameras that already have built-in Wi-Fi may not recognize the SD card.) *I purchased this to use with a camera I previously owned, but I quickly switched to a camera that wasn't compatible, so I only used it briefly right after purchase. Therefore, I haven't been able to confirm its operation for this listing, so I'm listing it as "junk" just in case, although I don't believe it's broken. There is no instruction manual, but you can view it at the following website: https://direct.sanwa.co.jp/contents/torisetsu/400-ADRWISD_torisetsu.pdf Thank you for looking.
