Credit Card Terminals Stop Working Due to Expired Certificates

Credit Card Terminals Stop Working Due to Expired Certificates

December 17, 2014         Written By Natalie Rutledge

Thousands of credit card terminals shut down earlier this month, but for once, it wasn’t the result of a data breach.

Payment terminals made by Hypercom were originally developed with a 10-year expiration date on their cryptographic certificates. Those certificates expired on December 7, 2014.

Rather than displaying letters and numbers, the LCD screens on the machines went blank. This left store owners without a way to process credit card payments.

Equinox Payments, the company that owns Hypercom, is currently working with their customers and distributors to replace the certificate and make the terminals useable once again.

“Many of these terminals have been successfully updated in the field. Unfortunately, a subset of them can’t be fixed in the field which means they’ll need to be sent to our repair facility,” Stuart Taylor, vice president of payment solutions for Equinox, told KrebsOnSecurity.

The company is directing affected store owners to this page for assistance.

The blank screens only occur after the terminals have been power-cycled, which most merchants do on a daily basis. For those who do not power-cycle every day though, there is still a chance that their machines will work for the time being.

If your store has been impacted by this certificate expiration, contact Equinox for support.
