Google's plans on a payment system are giving some people amusement. (1, 2, 3). Synopsis: it's a merchant oriented system, based on credit card. Direct "Paypal" model in other words. (This is a little unfair to those who invented the model, before Paypal, but hey, history sucks.)
Question is, would you or I do any different? That's a tricky question. Probably not, because Paypal is about as vulnerable as a unchaperoned princess on the way to her first ball. I'd be keen to migrate that model away for fraud reasons, but the "standard approach" has a lot of merit going for it right now.
This column waxes on without limit about how the planet will spin faster and the sun will shine brighter when google releases, due to all the hook-ins with other google products. Roight. But seeing as I murmured that eBay was looking ok the other day, I feel compelled to point out this statement: "Since eBay is already in deep trouble, it poses no threat to Google either way." Huh!

WhoPay: : a Scalable and Anonymous Payment System for Peer-to-Peer Environments Kai Wei, Yih-Farn Chen, Alan J. Smith and Binh Vo

An electronic payment system ideally should provide security, anonymity, fairness, transferability and scalability. Existing payment schemes often lack either anonymity or scalability. In this paper we propose WhoPay, a peer-to-peer payment system that provides all the above properties. For anonymity, we represent coins with public keys; for scalability, we distribute coin transfer load across all peers, rather than rely on a central entity such as the broker. This basic version of WhoPay is as secure and scalable as existing peer-to-peer payment schemes such as PPay, while providing a much higher level of user anonymity. We also introduce the idea of real-time double spending detection by making use of distributed hash tables (DHT), which further improves the security level of WhoPay. To evaluate how well WhoPay distributes load among peers, we have run simulations with several different configurations. The simulation results show that the majority of the system load is handled by the peers under typical peer availability, indicating that WhoPay should scale well.
To which, Daniel comments that "the main idea is simple: rollovers are handled by the first user who received a coin rather than directly by the issuer. If the user goes off-line, the issuer can temporarily take care of the rollovers. This is the innovation of PPay. This WhoPay is basically an anonimization layer on top of PPay." As commented from time to time, a lot of good research is going on in p2p space.
In more PayPal/eBay news, PaymentNews reports that the AuctionBytes.com's Ina Steiner has commented on the new eBay policy of banning other payment systems from auctions. Ostensibly for user safety, there is some user skepticism, and notions that this is positioning in advance of google are going to be hard to shake. Read this snippet and make your own mind up:
From time to time, as new payment services arise, eBay will evaluate them to determine whether they may present trust and safety concerns and are appropriate for the marketplace. eBay will consider the following factors, among others, in making its determination:
- Whether the payment model offers substantial financial, privacy and anti-fraud protection for buyers and sellers
- Whether the payment model raises the potential for confusion among eBay users, or involves incentives that may present fraud concerns
- Whether the payment model involves precious metals, or other non-cash (points, miles, minutes, coupons, discounts) as consideration
- Whether the payment service has a substantial historical track record of providing safe and reliable financial and/or banking related services (new services without such a track record generally cannot be promoted on eBay)
- The identity, background and other business interests of the payment service sponsor
- The license/regulatory status of the payment provider in the countries where it provides payment services
