1) Watching ads on your computer/smart phone
2) Checking in when shopping at certain stores - you scan the bar codes of certain items (Ex. Marshmallows, Graham Crackers, Glue) - It finds stores closest to your location and will even show a map of the area.
3) You can check in some of the items at your house if you said that you purchase it
Jingit is only in the beta stage but from what I see, it looks like it is going to be a great site. You can earn up to $10 per week so up to $40 each month by just watching a few ads or scanning a few bar codes on your smartphone. They give you a debit card, so you can recharge it with all of the money you made and can use it wherever you would like to. Take a look and let me know what you think!
