Ever wish you could easily implement mobile payments? This excerpt from Matthew A. Russell's PayPal APIs: Up and Running introduces Mobile Express Checkout as an easy way to handle mobile transactions.

Figure 2-12 shows Tweet Relevance as served up on a mobile device and Figures 2-13 and 2-14 demonstrate the MEC user interface.
