So far most gas pumps are still MSD Contactless.
Gas pumps that are EMV Contactless:
Maverik (all)
Loves (all)
Costco (all)
Chevron (some locations; Gilbarco pumps with Gilbarco POS only; Wayne pumps and/or Verifone POS still MSD Contactless pumps)
Speedway (all) (excludes Speedway Express)
Safeway
Quik Trip
Also think I've seen some 76 and unbranded stations with Gilbarco pump and Gilbarco POS have EMV Contactless on the pump but most still MSD even with that pump/register combination.
User sees no difference in a gas pump with EMV Contactless vs. MSD Contactless. Main difference is most who hang on the MSD Contactless keep having a zip code prompt with Contactless (probably is the reason why they keep hanging on to MSD Contactless as they were many of the same gas station chains who did not roll out EMV until they could get an EMV with zip code prompt working).
