What I do is I have a Paypal debit card. You can order it and is free and you can link it to a checking account and when your are using the card to pay for something that cost more than the amount of money available in your Paypal account then it will seamlessly withdraw it from your checking account.
It is a Mastercard so you can also use anywhere and just use it as a credit card to pay at restaurants or to get anything.
Well you have to be 18 to use Paypal as per their terms of use so yes you will have to be 18 to order the Debit card. To use it then as long as is a debit card all you need is your pin number and to use it as a credit card then your signature or buy online from places like Amazon. But some places may require for you to show an id and if you lied about your age then they will require a different form of payment.
Yes, you can withdraw it to your banking account.
Don't you have to be 18 or older to get those?
Yes
