Amazon's Google Problem

PayPal, which has more than 100 million active users, is a key business for San Jose, Calif.-based eBay, accounting for $335 million, or 24%, of its $1.39 billion in first-quarter revenue.

eBay, which could prevent its users from using Google Payments under its terms of service, needs to take Google Checkout seriously, says Ina Steiner, of the trade publication AuctionBytes.com .

"A growing number of consumers are concerned about fraud on online auction sites, and some are skeptical of using PayPal,'' she writes. "Seeing a seller is a Google-approved merchant with credit-card protections may allay some fears.''
