Networking Without Giving Out Your Phone Number
Every other detail you give away at an event can be walked back. Change your email, ignore the LinkedIn request, let the newsletter go to spam.
A phone number is different. Once it is in somebody’s CRM it is in their CRM, and in whatever they sync that to, and in whatever they sell three years from now. You will find out slowly, through calls at 11am from numbers you do not recognise.
This is why people hesitate at the badge scanner, and it is not paranoia. It is an accurate read of how the data moves.
Hesitating is not the same as being unwilling
The worry is specific and reasonable:
- Sales calls and WhatsApp messages you did not ask for.
- Your details in a sponsor pack, because a scan at a stand counted as consent.
- A QR code carrying more than you thought it carried.
- No record of who has your details.
- No way to undo it.
None of that means someone does not want to talk to you. It means the exchange needs to be a decision, not a side effect of walking past a scanner.
Give the smallest thing that works
Not every conversation needs the same access. There is a ladder, and most exchanges can stop partway up:
- Keep talking here, now.
- Swap emails or professional profiles.
- Exchange a digital card — name, role, company.
- Swap numbers, because you both want direct contact.
Step four is where most people start, out of habit. It is rarely where the conversation actually is.
Ask out loud
One direct question removes the ambiguity, and it takes a second:
- “Shall we swap details?”
- “Email or WhatsApp — which do you prefer?”
- “Can I scan your card?”
A badge scan is not an answer to any of those. Somebody scanning your lanyard at a stand has taken an action; you have not made a decision. Those are different things, and the difference is the whole of consent.
Know what your own QR code says
Before you hold up a networking QR, check four things:
- Which fields it actually contains.
- Whether it discloses them on scan, or only starts an exchange.
- Whether you can change what it points to afterwards.
- Whether you can see who scanned it.
Plenty of digital cards encode a phone number straight into the code. Anyone who scans it has it, whether or not they ever speak to you again.
Faydo Connect is built the other way round. The QR card is optional and carries name, role and company — not your number. A scan starts a request: Accept swaps numbers, Pass shares nothing and needs no explanation. Every share is one line in a ledger only you can read, and there is no member list for sponsors or for us.
Keep the note and the card apart
Two different things, doing two different jobs.
Your private note — what you discussed, why they matter, what you owe them — is for you. Nobody else reads it.
Your card — name, role, company — is what you hand over. Your number sits behind a separate yes.
Confusing the two is how a useful conversation turns into a permanent claim on your phone.
The honest limit
No service can undo a number somebody has already typed into their own phone. Faydo can end future access through Faydo; it cannot reach into a stranger’s contacts.
Which is the argument for deciding before, not regretting after. Attention is renewable. Your number is not.
