From Money’s recap of the Apple Pay CurrentC battle:

Now, seven months after Apple Pay debuted, the retailers are still struggling to hold the line. MCX member BestBuy recently announced it would start accepting Apple Pay, and Dekkers Davidson, the group’s chief executive, resigned one day later “to pursue other opportunities.” But the internal strife distracts from MCX’s biggest failure: The collective has thus far proved unable to get its app into the marketplace. CurrentC remains months away from reaching most consumers. A limited test in a “mid-sized market” is planned for sometime this summer, with a wider launch scheduled for later in the year.

A remarkable lack of execution.

Experts say retailers face two major obstacles in their efforts to create their own alternative payments solution. First, it may simply be too difficult to corral enough competing merchants into a coherent, cooperative group—especially when one of those merchants, Walmart, poses an existential threat to the others.

And my favorite line from the whole piece:

Apple Pay has the edge in the one feature that matters most: it actually exists.
