Software considerations

• Affordable (and preferably free)– and runs on affordable hardware

• Accommodate modular structure, and automatically generate & carry forward ID numbers between clusters, households, adults and pregnancies, with no manual entering of numbers

• Accepts Unicode to allow for Amharic and Tigrinya languages• No dependence on the internet, because there mostly isn’t any

Hardware considerations• Run Android• Inexpensive (84 units + cases + extra batteries + import duties)• Readily available in bulk• Robust• Excellent battery life• Small enough to be held in one hand, but with a large enough

screen so that long option lists could be displayed without scrolling

And the winner is…

In-field data reporting

In each survey team, data weretransferred at the end of each day from the tablets to thesupervisor’s laptop, using USB Cables.

In-field data reporting

Data were automatically imported into a Microsoft Access database to create a daily monitoring and query report

Data encryption

• Built-in Android encryption on tablets

• TrueCrypt encryption on laptops

The biggest lesson was…

…ስለተዋወቅን ..Some non-Latin characters (such as those used in Amharic) can take up more computer memory than Latin characters. This has the potential to slow down data collection programmes. Many thanks to the CSPro developers for rapidly responding to this problem and releasing a new version of the Android software in time for our survey.
