Participating traders primarily use New Zealand's banking system to settle payments, although Trade Me now offers sellers the ability to accept credit card payments by 'Ping' (formerly 'Pay Now'). Australian sellers must have a New Zealand bank account, while sellers from other countries are not allowed on the site without special approval, which reduces the potential for fraud. Many buyers pay cash on pickup with larger items – probably partially due to the relative concentration of the New Zealand population in a relatively small number of urban areas.
