Wal-Mart's move into health…mHealth?

This editor’s piece by Sara Jackson on FierceMobileHealthcare is an interesting confluence of what Wal-Mart is actually doing (putting out an RFP to expand their tiny walk-in clinic operations, getting bids on vendors to provide clinical and diagnostic services) and what it could get into (QR codes for customers to mHealth applications to providing remote patient monitoring). Wally World (as it’s nicknamed), indeed. Your call on how likely this all is. Do Walmart’s early moves foretell a leap into mHealth?
