I am back from being part of a retail study tour covering four major cities in the US and in each I saw lottery vending machines like these. Usually in public places, often outside of shops. You can buy game tickets as well as scratch tickets.
While Australia is way ahead of the rest of the world in terms of online lottery ticket purchase options, the US is way ahead in terms of self serve physical ticket / game purchase.
No matter how you look at it, the route to market disruption is supplier driven in this space.
I suspect the only reason Tatts isn’t doing these is that the laws in the various states wont let them.
