A little while back, The Royal Canadian Mint started up the MintChip Challenge and invited developers to re-think and share ideas for how a digital currency can be used. Developers were encouraged to create applications that showcase digital payment applications using MintChip, which is currently in development. With 500 of the developer kits issued, developers created those apps and now, it's time to vote for the winners.
Winners will receive approximately $50,000 in gold from the Mint as well as promotional exposure. The video you see above comes from the folks at taab, who as you can tell, created their app using the BlackBerry 10 Dev Alpha as well as providing offerings for Android. If you interested in reading why the Dev Alpha was chosen or their thoughts on QNX and BlackBerry 10, they've got a great post written up explaining it all.
There is plenty of applications listed in the gallery, so if you're looking to vote on them you can head over to the official website to get started. If nothing else, it's a great showcase of how developers are envisioning the future of payment processing including the use of such things like NFC.
