Self-Serving Checkouts

'Tech... kinda... alittle bit of spamish'

Woolworths trial self-checkout technology

These checkouts are in the woolworths I go to and I think they're great. I use them when I want to buy a thing or two and just wanna get in and get out. Obviously when I buy too much stuff I'll use the normal checkouts so I don't handle all the stuff.

Today however, I saw that the Westfield Coles also has these Self-Serving Checkouts... and I noticed, its exactly the same as the Woolworths one but red...

'Aren't Woolworths and Coles like in a war or something, why are they exactly the same!?'

Theres only three reason why I think they're 1 to 1 alike;
1) The Self-Serving Checkout interface is owned by someone so Coles bought it cause they can't design their own
2) Coles wanted customers to be familiar with the technology so they made the interface same as their competitor
3) Coles and Woolworths are working together to bring down all local outlets
