The Smart Crowd was once Virtual Bee, and before that was known as Key for Cash. They offer opportunities worldwide, not just in the United States if you meet their requirements.
The job is basic data entry. You look at scanned forms online and input the information online. You may also have to make the occasional phone call or look up information online.
Pay is very low, and it can be difficult to earn even minimum wage at this job. It's extra money at best, nothing more.
Experience is not required. You take a test to show your data entry skills. If you're accepted, you can work when you want. If work is available, you can do it. You are an independent contractor - not an employee.
