How I Built a Digital Namecard That Remembers People For Me

The problem: I couldn’t remember who I met

As an AI strategy consultant, I’m in networking spaces often — SME events, E3 Power Team sessions, bootcamp open days, speaking engagements. Every time, the same thing happens. Someone hands me a name card, or we just quickly scan each other’s WhatsApp. It feels efficient in the moment.

Then I get home. I open my phone, and there’s a new contact saved with just a name and number. No context. No memory of what we talked about, which event it was, or why I should follow up. Multiply that by every event I attend, and I was quietly losing dozens of good connections a month — not because I didn’t care, but because there was no system holding the memory for me.

The handshake was never the problem. It’s what happens — or doesn’t happen — in the days after, when the memory of who they are starts to fade.

What I built to fix it

So I created a digital namecard that does the remembering for me. Here’s how it actually works, in the order a person experiences it:

1. They scan my QR code. It saves my contact directly to their phone — no typing, no mistakes.
2. They can come back to the same page afterward and leave a few details for me — their name, company, and a note on how we met — so I can remember and follow up properly.
3. Or, they can WhatsApp me straight from the card. This is the part I’m most happy with. One tap opens a chat with me, already saying who they are and where we met. That message becomes a record in both of our phones, instantly. No waiting, no forgetting.
4. On my end, I have a private back-end I can log into, where I see everyone who filled up the lead form — their details, when they connected, and from which event. I can mark them as followed up, add notes, and keep track properly instead of relying on memory.

The process now feels almost seamless. Someone I meet at an event can save my contact, message me instantly on WhatsApp, or leave their details if they’d like me to reach out — and either way, there’s a record somewhere instead of nothing.

The honest limitation — I’ll say it plainly

I want to be upfront about something, because I think it’s more useful than pretending this is perfect. If someone simply saves my contact and doesn’t fill up the form or message me on WhatsApp, I won’t be able to capture them on my end. The card removes a lot of friction, but it can’t force anyone to leave their details if they choose not to.

That’s exactly why I built two ways to connect instead of one. The WhatsApp button exists because I knew the lead form alone wouldn’t catch everyone — some people will message immediately, some prefer to fill a form later, and some, honestly, will do neither. What matters is that far more people are captured now than when I only had a paper name card.

How I actually built this

I’m not a developer. I built this by describing my problem in plain language to an AI build tool and letting it write the actual code. Specifically, I used Google AI Studio’s Build mode, running on Gemini, which also set up the backend database (Firebase) where all the leads and tracking get stored — so nothing disappears when someone closes their browser.

I keep meeting people at networking events and forgetting who they are afterward. I want a digital namecard that:

1. Lets people scan a QR code and save my contact instantly to their phone.
2. Lets them come back to the same page and leave their name, company and a note on how we met, if they want me to follow up.
3. Gives them a one-tap WhatsApp button that opens a chat with me, already saying who they are and which event we met at — so we both have a record instantly.
4. Gives me a private back-end I can log into (only me, secured with my own Google login) where I can see everyone who left their details, mark them as followed up, and add notes.
5. Tells me the moment someone new leaves their details, so I don't miss it.

Build the visible card first so I can see it working, then add the tracking quietly in the background, then build my private dashboard last.

If you want to try building something similar, the platform matters less than the brief. What made mine work was describing the actual problem — forgetting who I met — instead of just asking for “a nice digital business card.”

What I’m improving next

This card is very much a living tool for me, not a finished product. Over time, I’ll keep adding functions as I notice new gaps — the same way the WhatsApp button and the upfront QR code came from actually using the first version and feeling the friction myself. If you build your own, I’d treat it the same way: launch it, use it at your next event, and let what annoys you tell you what to improve next.
