We
have found that most card readers in the AV-TS Black Wedge units are not
capable of reading our standard "memory only" voter smart card. To allay
any fears about our current production, all Blue and White AV-TS units ever
produced are fully capable of reading all versions of the smart cards that we
deliver. And all desktop smart card readers are capable of reading all
versions of the smart cards that we deliver.
The
reason for this incompatibility is due to the Model of the smart card reader
installed in the Black Wedge units. The Black Wedge units were made with
the original Model 171 smart card reader (a.k.a.
171TDAI, 171T1DAI, regardless of
revision). The Blue and White units are made with a newer Model
171A smart card reader. The Black Wedge units can only
read/write "microprocessor" type cards, they cannot read/write "memory only"
cards. However, the newer Model 171A readers (a.k.a.
171A, 171ATDAI regardless of revision) can
read/write to all types of cards we deliver. I have confirmation on this
information from Axiohm Corporation who manufactures these card
readers.
The
four types of smart cards we have delivered can be categorized by the shapes
of their contact areas. There are two microprocessor
types, the "L" shape and the "oval" shape. There are
two "memory only" types, the "X" shape and the "Atmel" type. Please see
the attached JPEGS for a pictures of these contact shapes.
The
only state we run Black Wedge units is in Tennessee and then in three
counties, Shelby, Bradley, and Rutherford. These accounts should only be
using the "microprocessor" type of card as voter cards. These
accounts have been using the "microprocessor" type smart card all along
because when they were sold the units, that type of card was the only one
available. Most of their smart cards will already be of the right
type. It has only been recent shipments of smart cards to Shelby County
that has brought this to light.
Fair
warning: If anybody does any Monday morning quarterbacking on this one,
I'll come looking for you to find out why this information wasn't disseminated
before.
