I applied and did receive the SpeedPass keychain wand a few months ago. It is quite simple to use. Place it on the SpeedPass area of the pump and await the red light to come on.
The MSC for the station requests the shopper to "check" a few pumps in order to ascertain if the SpeedPass indeed, works.
You are not required to use it as a means of payment. That is your decision.
Over the past months, I've been checking the pumps for working receptions. It varies. Some stations have working Speedpass pumps, whilst others, do not. I simply report the findings.
A word to the wise, however: when using the SpeedPass apparatus. do cancel the action. Press the clear or cancel buttons several times until the Speedpass light fades out completely.
Do not walk away from a lit SpeedPass pump until then!
You should know why!
