Bync is a new site that aims to deliver accurate daily deals based upon what you buy. Bync connects directly to your bank and credit cards to see what you buy and where you buy it from. Using that data, Bync is able to let you know when brands and stores that you like are offering deals.
Letting a start-up access your banking and credit card history may sound a little creepy, but Bync's methods are the same as those used by grocery store loyalty programs. The company is working with over 10,000 banks, so it's more than likely that your financial institution is connected to Bync. The start-up still looks to be in private beta testing; you need to ask for an invite to join.
