A friend, a local coffee shop owner, asked us an idea to thank his customers for their loyalty. And we created this device!

Step 1: What You Need

1 Arduino
1 Thermal Printer
Some leds
1 Small breaderboard
4-6 jumper wire
5v rechargeable battery
9v battery
1 plexiglass box

Step 2: How It Works

When a customer checks-in on the coffee shop facebook page (FB LINK), wins free drinks, cocktails, coffee and dozens gifts from other small businnesses. Gifts are printed randomly.

Watch below how happy customers react :)

Step 3: What's in It for Me?
