Last year, we used Android tablets with micro SD cards. The app would output a CSV (comma separated value) file. A CSV is basically a text file with different values separated by commas or tabs. For example, if you were collecting team number, alliance, and points total (just for example) the file would say something like "1836,blue,120" or "1836 blue 120".
We would grab the files off the SD cards and put them on one central computer. You can then drag the files into an Excel document and it is automatically sorted in to the columns based on the commas.

This year, we decided to move away from the digital scouting and go back to paper because we found that it was more reliable to promoted more detailed data collection -- team members took it much more seriously when they actually had to actively fill in "No" or "0" rather than just selecting a box. This way, it is just as easy to collect accurate data.
