BlackBerry maker Research in Motion (RIM) has launched a payments development toolkit to encourage developers to create their own transactional apps for selling digital goods and services over the handset.
The early release Payment Service SDK can be integrated by developers into their applications as a library as long as it is distributed through the BlackBerry App World storefront.
Users can incorporate options such as subscriptions, feature unlocking and pay per use with their customers then making the purchases through their BlackBerry IDs, using various options such as credit card, PayPal and carrier billing, without having to leave the app.
