Rento is made for the current market, more and more are moving away from cheques, cash or even paying by card, and the main reason is safety, so with rento you bypass the security aspect, and as the transaction is completed by cryptocurrency this makes for an easy secure transaction.  

The annoying part of changing currencies will disappear, this should open the idea of Rento to the average person.

How will you resolve customer issues like for instance a payment is made but the item is not available when it should be, and how safe will your app be as there are so many apps out there only as strong as the phone encryption?

Some people don't have a lock on their phone so if the phone was stolen would they be able to access the app?

Great project and really looking forward to using it soon
