Guides, plainly written
Straight-talking articles on digital contact cards, NFC business cards, team branding and turning taps into leads — written for people who actually get phoned.
Looking for the product rather than the reading? NFC business cards explains what the card does, what happens when somebody taps it and what it costs. Google review cards are the other half of the range. Or start with a free digital contact card and share it by link or QR today.
Printed rangeUK business card size: 85 x 55 mm, and the other size you will meet
The standard UK business card is 85 x 55 mm; a bank card is 85.6 x 54 mm. The difference, pixel sizes at 300 dpi, and what to send a printer.
QR codesYour LinkedIn QR code: where it is, and when to use something else
Where to find your LinkedIn QR code, how to share or print it, and when a QR that opens your number, email and LinkedIn together is the better choice.
How it worksDoes my phone have NFC? How to check, and how to turn it on
What NFC on a phone is, how to check whether yours has it, and how to turn it on for Android and iPhone. Plus what to do if your phone has none.
Printed rangeHow big does a QR code need to be? The minimum size, and the 10:1 rule
We printed a QR code at 18.4 mm and scanned it from 400 mm. The minimum size for a QR code, and how big to go on cards, stands and banners.
Access controlWill an NFC card open my gate? The answer is a frequency, not a brand
Most access fobs are 125 kHz and most phone-readable cards are 13.56 MHz. Here is how to tell which your gate reads, and when one card can do both jobs.
NFC cardsDo NFC cards work without NFC? Tap, scan, and the phones in between
Which phones tap, which ones do not, and what happens either way. The short answer is that a card with a QR on it works on every phone you will meet.
NFC cardsWhat happens to your NFC card when you change your phone number
Change your number and most contact cards quietly stop being true. It depends on where the details live — on the chip, or somewhere you can still reach.
ReviewsGoogle review cards: the honest way to ask, and the shortcut that breaks the rules
Review cards work. Review-gating breaks Google's policy — and in the US, the FTC's 2024 rule. The difference, and why ours sends everyone to the same page.
VerificationIs that number still real? How number verification works on your card
A number on a card is a claim, not a fact. How a verified mobile works, what the badge means — and what it deliberately does not.
TradesNFC business cards for tradespeople: why a tap beats a paper card on site
On a job a paper card gets wet, lost or binned. An NFC card shares your number, WhatsApp and reviews in one tap or scan — and updates itself.
Digital cardsDitch the paper business card — or give it a live QR
Paper is not the problem. Frozen information is. One live profile shared by QR, link or a tap — on plastic, metal, or printed card.
TeamsOne company card for your whole team: consistent contact details, updated once
One company-branded card for the whole crew: brand-locked, inherited by new joiners, and re-branded for everyone in a single change.
Lead captureContact-back, explained: turn every tap into a lead
A paper card only gives your details out. Contact-back sends theirs back to you — no app, no account, free on every profile. And where the lead goes next.
