$4mil at 42c via pattersons, page-61

Average revenue per user is forecast at around $4 on ZipT. Remember though, the minimum top up deposit is $5. Obviously, the amount people use this in a chargable way is important, but I even if they get only $1, they'll still do well and the app becomes more analogous to an insurance play or some such similar whereby they reinvest the float and the primary revenue is the interest held until the float gradually converts and can be booked as revenue.

If you do the maths on that, 5M users (which I think was what was acquired from Mpire and excludes the Indian upside) gives:
$5 min charge x 5M x 5% = $1.25M/year.

Now say you had 20M customers, who didn't use the service much (never top up) you get a current PE of 4. Which is purely on interest earned. Then you add in actual reveune from use as well as AussieSim and the bluesky there with white labeling it overseas, etc...

Looking pretty cheap to me.
