Generally it is one store at a time with contracted teams specializing in POS, PIN pads, handhelds, and the computers that run a retail storeI thought I'd just throw out there that one of the Meijer stores near me got new terminals this week - Verifone MX915s to replace the MX850 or MX860 units they had for a really long time. At this particular location, I never had issues, but at the other, I would get a "Hold Near Reader to Pay" error, so I'm hoping that one gets replacements soon, too. I'd be curious to see their numbers for people actually using it since launch, especially since their gas pumps are also NFC-capable.
That being said, does anyone know how larger chains typically do terminal upgrades - is it on a store by store basis or a rollout across the board?
Are you holding it up to the LCD of the MX915?
