MAGNETIC CARD READER WITH ELECTROSTATIC DISCHARGE STRIP
A slidable magnetic card reader particularly suitable for magnetic payment cards having at least one longitudinal edge surface, the card reader including a magnetic card reading head operative to provide a data output in response to sliding thereby of a magnetic card bearing readable magnetically encoded data and a sliding track defining assembly including an elongate magnetic card edge engagement surface arranged for sliding engagement with a longitudinal edge surface of a magnetic card, the elongate magnetic card edge engagement surface extending at least to a location generally underlying the magnetic card reading head, at least a portion of the elongate magnetic card edge engagement surface being electrically conductive and being coupled to electrical ground.
1 . A slidable magnetic card reader particularly suitable for magnetic payment cards having at least one longitudinal edge surface, said card reader comprising:
a magnetic card reading head operative to provide a data output in response to sliding thereby of a magnetic payment card bearing readable magnetically encoded data; and
a magnetic payment card sliding track defining assembly including an elongate magnetic payment card edge engagement surface arranged for sliding engagement with a longitudinal edge surface of a magnetic payment card, said elongate magnetic payment card edge engagement surface extending at least to a location generally underlying said magnetic card reading head,
at least a portion of said elongate magnetic payment card edge engagement surface being electrically conductive and being coupled to electrical ground.
2 . A slidable magnetic card reader according to claim 1 and wherein:
said elongate magnetic payment card edge engagement surface extends to two opposite sides of said location underlying said magnetic card reading head; and
at least a portion of said elongate magnetic payment card edge engagement surface on each of said two opposite sides of said location underlying said magnetic card reading head is electrically conductive and is coupled to electrical ground.
3 . A slidable magnetic card reader according to claim 1 and wherein said elongate magnetic payment card edge engagement surface is electrically conductive substantially along its entire length.
4 . A slidable magnetic card reader according to claim 1 and wherein said magnetic payment card sliding track defining assembly is electrically conductive.
5 . A slidable magnetic card reader according to claim 1 and wherein said elongate magnetic payment card edge engagement surface comprises an electrically conductive strip.
6 . A slidable magnetic card reader according to claim 5 and wherein said electrically conductive strip is die cut from a metal sheet.
7 . A slidable magnetic card reader according to claim 5 and wherein said electrically conductive strip is die cast.
8 . A slidable magnetic card reader according to claim 1 and wherein:
said elongate magnetic payment card edge engagement surface comprises an electrically non-conductive strip including at least two cutouts; and
an electrically conductive strip including at least two protrusions which resiliently extend through said at least two cutouts.
