Online payment services provider Paymate has moved its headquarters from Australia to the US, auctionbytes.com reports.

Paymate is an approved online payment method on eBay.com, serving buyers in 57 countries and sellers in Australia, New Zealand and the US. The company has also appointed Garrett Gafke as chief executive officer.

In other news, Paymate has introduced a risk assessment service for large online merchants. Dubbed Paymate Sentinel, the risk-managed payment gateway service plugs into the merchant's website to replace a traditional payment gateway, allowing merchants to make use of an existing merchant facility or get a new one with approved major banks.
