SDカード R&W is a free app developed by Panasonic Corporation for Android devices. This app allows users to easily back up photos, videos, and contacts from their smartphones and tablets. The app requires SoftBank SELECTION Wireless SD Card Reader & Writer (sold separately) to function. The slim and compact body of the app makes it easy to carry, and it allows users to view and play photos, videos, music, and documents (Word, Excel, PDF, etc.) in the SD card. Users can also connect their NFC-enabled smartphones with just a touch.

The app is compatible with Androidx, and it may not be able to view or play some files depending on the user's smartphone or tablet. The service will end on July 31, 2021, and future OS updates may not be supported. Before using the app, users must read the instruction manual enclosed with the product and use it correctly.
