While the have established the credit card vault facility, getting merchants to use it, and deciding upon who will pay the merchant fees is am important issue. If Rewardle are willing to soak up the merchant fees, then it becomes a no-brainer for a merchant to use it, and uptake of Rewardle will be enhanced. At my local cafe they havent turned on this facility so i expect there must be some technical issues to overcome.
