  In this paper we present the report on the design and development of a
platform for the inter-generational exchange of favors. This platform was
designed using participatory design approach during a 24-hour hackathon by a
team consisting of younger programmers and older adults. The findings of this
report show that inter-generational cooperation in which the older adults serve
as representatives of the end user, not only improves the design and
development of the application, but also provides an effective method for
designing and applying solutions aimed at improving the security of older
adults while using online and mobile tools.
