MicroSD adapters allow users easily to transfer files from portable devices to computers or to store files on a small medium. Although many computers have integrated card readers, they are not directly compatible with microSD cards and require adapters.
Using a microSD card adapter allows computers to read directly from and write to microSD cards. As such, users can retrieve data written to microSD cards on portable devices such as cameras and phones without having to connect the device to the computer. Similarly, microSD card adapters allow users to treat microSD cards as portable storage spaces, similar to USB disks.
