If you haven't already, I'd go through the troubleshooting steps for the <A href="http://squ.re/2wQ1fHH" target="_blank">Magstripe reader</A> as well as the <A href="http://squ.re/1UgOr5U" target="_blank">app</A>. If those don't work out for you, give our <A href="http://squ.re/contact" target="_blank">CS team</A> a call and they can investigate further for you.</P> Tue, 05 Feb 2019 19:21:01 GMT https://community.squareup.com/t5/Payments-Troubleshooting/mag-reader-won-t-read-cards-brand-new/m-p/108517#M27381 puka 2019-02-05T19:21:01Z
