You have at least

tion on the phone or on its STK (SIM
application toolkit) where the carrier
distributes the application as part of
its SIM chip.
CReeGeR: You have several different
ways to develop applications. How do
you make those kinds of decisions?
ReaLini: You have to look at things
early and often because this is a moving target. We use the 80/20 rule, with
80% of the devices providing a good to
great user experience and the other
20% providing adequate user experience.
to Y: The key is to have a tiered strategy and not go for the silver bullet.
Don’t say which device is the right one.
While all devices could probably be
supported, you have to ask, “What is
the right functionality to have on each
platform, and what is the minimum
functionality required for any device?”
ReaLini: The CTO of my company
puts things in three buckets:
˲ ˲ I know it works because I’ve certified it.
˲ ˲ I think it works because the device
manufacturer said it’s totally compatible with earlier implementations.
˲ ˲ I have no idea if it works because
multiple changes have happened.
This is important because your con-
sumers and/or employees have to be
able to make a decision from the thou-
sand or so devices that could be pur-
chased. You have to help them identify
the 200 or so devices that will probably
work well and the 50 or so devices that
have been certified.
