In North America (U.S. and Canada) you may have an agent (parent or guardian) who is over the age of 18 sign up for you; however, it must then be registered under their name. Payment (whether this is made up of checks, or EFT - Electronic Funds Transfer) will be sent to that person. If you're under the age of 18 and someone signs up for you, you have to be careful that they're trustworthy and that they'll actually give you your paycheck.EFT, or Electronic Funds Transfer, is a direct deposit system where Google automatically funds your bank account (no credit cards), which must be a North American bank account, with your payment (minimum $100) instead of sending a check (31st of the month?). You must verify it first, kind of like what PayPal does, when they credit your account with some amount and you have to identify it and submit it to the site. Then you're good to go.Some of these may not be available to users outside of the U.S. or Canada. However, I heard that they recently added EFT for Australians. A strange country to pick!If you're under the age of 18, it might be best to sign up for another service if you're strictly unable to get a guardian to sign up for you. As well, they're kind of picky anyways.
