Are you thinking about the mobile augmented reality geocaching game Pokemon Go? For retailers it was a neat way to attract new customers to their shops.
Yes, I remember when the Pokemon Go hype came up. It was very lucrative for café, bar or restaurant owners to have such a Pokestop close to their location, where they could catch Pokemon or get some items: "... Food and drink sales spiked by about 30 percent compared with a typical weekend.."

Its like poke hunting coins. Gotta get em all! I like the idea this really is a innovative project
It's funny that Pokemon Go is being compared to the 'a-drop' technology Gatcoin is implementing. I do see the extra value for merchandisers with this A-drop tech.
By providing coupons to people around your business you can attract them easily. Good idea !
The only difference with this one is, it's more serious... no kiddy play
