Interestingly, when told to read the card it gives signs of doing so as it normally would. it say downloading data. It then asks if I want to return the card to the same patient. After I click yes, I then get this error.
It is only when I request a report do I get this error. I can get a green light (turning to red when I insert the card).
Talking to the Apria expert he said he frequently gets the same error which he can fix by plugging and unplugging the device repeatedly. (Nicely, he raised no problems about I having a reader and offered to send me a new card on the chance the card was defective).
I would have thought if there was a problem with the card or inability to contact it, that it would give an error indication immediately.
