MEMORY CHECK

I stopped for gas this morning and the pump rebooted. I swiped my debit card, but instead of the usual

 Is this a debit card? Y/N 

query, the pump responded with

 MEMORY CHECK 

and a stream of self-test diagnostics. After about a minute (slow, but faster than rebooting my Windows laptop), the pump signaled readiness. I swiped my debit card again.

 MEMORY CHECK 

Could my card have acquired special powers? Having a “reboot” card might be cool, but it wouldn’t offset the loss of the “buy things” magic. No such luck; the card worked in another pump.
