MercadoLibre runs MercadoPago, a safety payment system. When adding MercadoPago in its listings, sellers allow buyers to choose among many payment alternative methods such as cash, bank transfers and credit cards or installments, among others.
Most of these transactions occur for marketplace items sold, but 30% occur outside of it.
