Which alternative payment systems interest you?

I’m currently writing a series of articles for the DevZone comparing the PayPal X Platform and its capabilities to alternative payment systems.

So far, I’ve written articles discussing Amazon’s Flexible Payments Service (FPS), Facebook Credits, and Google payment technologies including Google Checkout and Google Wallet (read my related blog post from last week on the latter by clicking here).

My articles look at the strengths and weaknesses of each of those systems, and especially how they compare to PayPal-based development and deployment.  For instance, FPS provides a similar sandbox-based development and testing environment to PayPal’s Sandbox and provides somewhat similar functionality to PayPal’s Adaptive Payments, but it is limited to merchants and consumers with Amazon accounts.  Similarly, the Facebook Credits API is similar in functionality to PayPal’s Express Checkout, but  is only usable by Facebook Platform-based applications whereas Express  Checkout can be used with applications built for any proper  Internet-ready application container and environment.

The series explores those points and much more, even down to the level of payment flow through some of the alternatives (example:  Facebook Credits as pictured below).
