From an OverDrive blog post: The days of having to dig your library card out when you’re trying to download an eBook at the doctor’s office (or park, or airport terminal, or a bar mitzvah) are over. With the latest update to OverDrive-powered mobile sites, users will have the option for their devices to store their library card numbers.
Starting now, when customers check out a title, the device will have a box where they can check “Remember me on this device.” The device will then hold the characters in its memory for 90 days after each use. This is an optional service. If a library requires a pin, it will still be required to check out titles.
This update is a part of OverDrive WIN, a series of platform enhancements that will streamline user experience and provide access to more content. Check back to see more enhancements to your service.
