Cafe Receipt App Tech Coffee Beans

This is an app-tech where you can get coffee beans by verifying cafe receipts. There's a feature to earn beans by watching ads every 3 hours, and in an app called 'Wondoo Pang', if you watch ads 4 times a day, you get an additional 10% bonus on your accumulated idle buffs. Cafe visit verification gives you 100 beans, and receipt verification gives you 500 beans. On-site payments start from 1500 won, and please note that coupon payments like gifticons are not eligible for receipt verification. Information on daily changing telecom discounts + partner card discounts for the cheapest coffee is also updated. There are many types of gifticons you can exchange your beans for, and exchanges start from 50,000 beans. I think it's a worthwhile app-tech for coffee lovers. (I started less than a month ago and have already redeemed one coupon.) I'm not sure about iPhones, but on Android, it's only available on devices with a USIM card.
