It seems that Google elaborates its functions when in addition to being a search engine, it launches new online payment service named Google Checkout, which will compete with already established names like PayPal. Google Checkout maintenance conceals the credit card number from the seller, creating a third party situation between a seller and a buyer.
Since eBay uses the PayPal service for its customers, Google Checkout provokes rivalry between the two entities. As a result, any seller caught offering Google Checkout to prospective buyers, faces having their listings cancelled, forfeiting their fees or even having their entire account suspended.
The decision to exclude Google's newest venture is yet another indication that Google is encroaching on areas that other companies consider to be their territory. Having created the web's most widely used search engine, Google has moved into email, instant messaging, word processing, spreadsheets, price comparison and now payments.
In its payments policy, eBay allows payments by traditional methods such as credit cards, personal cheques, money orders and cash, but strongly encourages sellers to offer payments through PayPal. However, eBay has updated its accepted payments policy to exclude specifically Google Checkout.
