Why I put digital business cards through a real team trial instead of trusting the demo
A card that works on a vendor's stand isn't the same as a card that works at 9am when someone's case has a magnetic wallet stuck to the back of it. I ran a full trial with my own small team instead of taking the demo unit's word for it, on the phones and cases we carry day to day, as part of a review on my site.
I test a lot of small business tools this way, on real staff rather than a clean unit, because the gap between the two is usually where the actual cost of a gadget hides. Digital business cards are a small purchase on paper. They're also the kind of small purchase that wastes a morning if half your team can't get them to work in front of a client.
What happened on Android phones
Three of our Android users had chips that needed a second tap because the phone's NFC reader landed somewhere different on the case than expected. iPhone to iPhone, both cards worked exactly as advertised, first tap, every time, no fuss. Mixed devices told a different story. It's a small thing to write down and an awkward thing to live through, standing at a table watching someone tap, pause, frown, then tap again while the person opposite decides whether it's worth the wait or whether to just ask for a phone number instead.
