<p>[QUOTE=&quot;calcol, post: 4623453, member: 77639&quot;]Failure to the read the chip when the card is inserted&nbsp; is probably due most often to dirt and grease.&nbsp; I&#039;m assuming that when the card is inserted, the electrical contacts surrounding the chip are used for all the communication rather than wireless.&nbsp; So with use and age, dirt and grease build up on the contacts of the chip and readers.&nbsp;&nbsp; The grease is from skin ... and these days, from hand sanitizer too.&nbsp; The active ingredient in hand sanitizers is usually an alcohol.&nbsp; But alcohols dry the skin, so sanitizer makers put in emollients, like mono- and di- glycerides, aloe, etc.&nbsp; When the alcohol evaporates, these are left behind on fingers and can be transferred to other things like credit cards.&nbsp; As dirt and grease build-up on contacts, their ability to function becomes variable, which why a card may work in some readers and not others.</p><p><br /></p><p>Sometimes some of the contacts work well enough for the scanner to read the card ID, but not complete the transaction.&nbsp; Recently my wife used a credit card, and it was declined, so she used another and it worked fine.&nbsp; Neither was anywhere close to the credit limit.&nbsp; However, I got an email from the credit card company concerning the first card that the chip couldn&#039;t be read properly and the mag stripe should have been tried.&nbsp; Well obviously, the chip was partially read.&nbsp; And yeah, she had been using hand sanitizer on her hands and also on the card itself.&nbsp; She washed the card later.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
