A renter is someone who rents items from owners on the Rent Items' Marketplace. By default, everyone who registers is registered as a renter.
Registered Renters vs. Not Registered Users
A user does not become a renter until they have registered. However, none registered users can browse available items in the marketplace. However, none registered user will need to register and become a renter in order to check out and place a rental order with an owner.
A renter will need to provide payment information such as a major credit card during the check out process of the rental shopping experience. This payment method will be billed upon placing a rental order.
Becoming an Owner
If you want to become an owner, your bank account information will be required when you list your first item on the Rent Items' Marketplace. Rent Items requires this information so it can pay owners when a rental occurs with a renter.
