  1. Ethernet connections are used for credit/debit transactions (and all other electronic transactions) in most modern shops. The bandwidth is much greater (much more information) than in a land-based telephone line, and in a typical day, the amount of bandwidth used is only a tiny portion of what’s available.

    On days near holidays, like Christmas, it isn’t too uncommon for ethernet signals to slow down or even be lost (dropped connections), because so many people are shopping at the exact same time.

    And by the way: some smaller, privately-owned shops still use dial-up connections for their electronic transactions. They are subject to the usual phone problems, and the problems get worse during busy times.
