well the open banking is the product they are after.....slide 19 shows what they aim to do from the merchant side (presumably this reduces transaction fees and also provides merchants with instant access to funds), and slide 20 shows what they plan to do for their collective customers (yes the digital wallet)

The whitelabel/banking business is probably only there for reputation and perhaps regulatory licences, but is not going to add anything to top/bottom line

still seems to me a big sell to get merchants to add another payment option to the mix, but the incremental increase they are projecting seems to indicate that they must expect significant traction somewhere (not to mention that they are paying ~140 times CY2020 EBITDA)
