The idea of a scorecard has merit but so too would be a companion definition of terms. What is the criteria for considering a 'solution' to be a mobile payment option that merits inclusion on this PYMNTS.com scorecard?

Besides definitions is being able to make an apples-to-apples comparisom as a scoreboard does. Click through to the linked first scorecard and one will find 13 mobile payment options on the scorecard ... including Android Pay which is not yet launched and has 13 financial institutions lined up.

While this article's analogy to a scorecard makes sense, imagine being at a the NBA Finals Game 6 tomorrow night and the scoreboard shows only points for the Golden State Warriors and only number of time outs left and number of team fouls for the Cleveland Cavaliers. That's basically what this initial scorecard by PYMNTS.com shows:

Even if this informal 'scorecard' above doesn't truncate when it posts, can one tell who is winning?

Further:
* Where is Facebook? (PYMNTS.com awarded Facebook as Payments Innovator of the year in March 2015 and Facebook is further along in mobile commerce today than Android Pay.)
* Where in M-Pesa Vodaphone and the many other 'Carrier Mobile Money' [CMM] providers operating in well over 60 [mostly developing] countries globally, helping countless millions realize better lives?
* Where are over 300 Carriers/MNOs supporting 'Direct Carrier Billing' [DCB] of well over $10B currently [projected to grow to $18-20B in the next ~3 years], partnering with the likes of ArpuPlus, Bango, Boku, Danal, Dimoco, Fortumo, Mobile Embrace, Neomobile, Net-M NTT DoCoMo, SLA Mobile, Zamano and others ... operating in over 110 countries.

Today, Carrier Commerce (DCB &/or CMM - both multi-billion dollar mobile payment sectors) operate in over 70% of the world's countries ... yet the quiet giant of Carrier Commerce [decentralized across 1-5+ Carriers per nation] continues to get virtually ignored in the mobile payment discussion ... in spite of Carrier Commerce also having about the biggest impact in helping advance the noble aims of Financial Inclusion (in developing and developed nations) in the world today.

A new industry association for Carrier Commerce Financial Inclusion is coming to help raise visibility of this vibrant industry and accelerate is growth - from its footprint to its breadth and depth of commerce services in the digital economy.
