Will be interesting. Reading between lines, I got the impression from the Chairman's interview with Alan Kohler that they are building a business/technology with the hope of being taken over (lets everyone get rich). He basically stated they want to be Paypal for instalments (& together I believe they were hoping Paypal might be interested). The concept/dream is admirable - I just can't see their upfront option to pay merchants (the only place I can see where the business would genuinely scale) being cost competitive. The advantage of the business is more with the customer than the merchant & for that reason I think the future upside is limited.
Of course, only time will tell.
