I like how easy it was for my business clients, when they are out in public places or attending events etc., with this app! It's very secure as well so we don't have any issues using our card readers at these types event locations where there could be potential risks involved (such as someone stealing your information). There were times before however if you did not properly link up everything would go wrong - but once linked all worked great!! Make sure though do test first because sometimes even after linking them into digital id will say "no data" meaning something else went bad during setup process & needs re-setting / troubleshooting again! Easy way around most things now days anyways!! We've been able use credit cards securely from anywhere since installing digitallyi d onto various android phones including iPhones too which has helped us tremendously while doing client work.
