implementation in pure Java makes it an ideal choice for inclusion in any application
that needs to use its features while remaining portable to hardware that may or may not
support SATSA.
Today's mobile applications leverage security solutions in a number of ways, but
electronic commerce is playing an increasing role in driving secure technologies to
mobile devices. To support secure commerce applications, the optional Contactless
Communication API provides the means to communicate with a number of wireless data
devices, such as near-field wireless devices and bar codes. The API provides support for
both proximity cards at a low level (where you exchange individual bytes) as well as the
NDEF, and it also lets you decode or generate bar-code images.
Security is a big topic, and this chapter has only scratched the surface. It's not like
cooking with spices; while you can dump a handful of peppers into a dish to make it taste
spicy, you can't just dump a handful of security APIs into your application and make it
secure. (Actually, they're more alike than you think: the resulting dish is as likely to be as
inedible as your application is insecure!) Designing a secure application requires care
and forethought, and if you're working to that end, be sure to consult one or more of the
excellent Internet and book references mentioned in this chapter for more details.
