Bump is a free app for Android and iOS devices that makes it very easy to transfer pictures and contacts between devices. Bump can also be used to transfer photos and contacts from your mobile device to your laptop or desktop computer. To transfer photos and contacts between mobile devices just gently bump the devices together (both devices need to have Bump installed). To transfer photos and contact between your mobile device and your computer just select files on your device, open Bump on your computer (it's browser based), and press the spacebar on your keyboard. See Bump in action in the video below.
Applications for Education
If you have your students create study groups that meet outside of classroom time, Bump could be a good app to have students use at the beginning of a semester to quickly exchange contact information with classmates. If you're looking for a way to move image files from mobile devices to computers for students to use in multimedia projects, lose the USB cables and Bump.
