Excess noise = 86 (Hex)
The MagnePrint™ circuit is sensing excessive electrical noise in the environment,
no MagnePrint™ data is available. Moving the reader away from noise sources
(monitors, speakers, etc.) may solve this problem. Note that this result indicates
that the noisy condition was present at the time the card was swiped. It is not a
real time indication that noise is present. For a real time indication that noise is
present see the Indicators property in the Transport application.
Data not available = 87 (Hex)
There is no MagnePrint™ data available for this card format. This could occur
when swiping a blank card.
