I think Flykk will only take off if ISX is able to secure enough merchants on their ecosystem to make it sensible for an individual to consider Flykk.
It should be similar to other e-wallets ie ApplePay, SamsungPay etc for their instance, a retailer/F&B outlet with them as an additional payment option where you don't need your wallet or card to be able to make a payment straight off QR code or a tap.
If they are able to gain enough traction for Flykk, this will be very very lucrative as the money would stay within the ecosystem of ISX and ISX will be able to profit from each movement and transaction.
Although, from the Flykk Wallet fees & charges document, there seem to be a cost for uploading off funds which might deter customer from picking it up.
