How digital business cards work with CardDeck

A digital business card is a web page about you, designed for phones. It has a permanent address — for example carddeck.co/yourname — and a QR code that points to that address. Whoever opens it sees your photo, title, company, contact buttons and links, and can tap Save contact to download a vCard file. Their phone's contacts app reads the vCard and adds you, with your photo and details filled in.

Nothing needs to be installed. The card opens in Safari, Chrome or any other browser, and vCard (versions 3.0 and 4.0) is a long-established standard that iPhone and Android contacts apps support. Because the card is a page rather than a printed object, you can change it after sharing: the next person who opens the link sees the new version.

CardDeck organizes this into four steps — create, share, capture and manage. The first two are what most people mean by "digital business card". The last two are what make it useful for work.

You create a card by choosing a template, adding your details and publishing. It takes a few minutes.

1. Pick a template. Templates are designed to look right before you change anything. Choose one close to your brand; you can adjust it later in the card designer.
2. Add your details. Photo, name, job title, company, phone and email are the essentials. Add the links people actually use — website, LinkedIn, portfolio, listings or a booking page.
3. Add a call to action. One button with a clear next step, such as "Book a call".
4. Choose what to show. Hide fields you don't want public; reorder buttons so the most useful one comes first.
5. Publish. CardDeck creates your permanent link and QR code.

Your card is now live. You can keep editing it; changes appear instantly for anyone who opens it.

You share a digital business card through any channel that can carry a link or show a QR code. The same card works in all of them.

• QR code in person. Open the card on your phone and let the other person scan it with their camera. Or print the code on a paper card, badge, sign or the last slide of a talk.
• Link in messages. Paste carddeck.co/yourname into a text, WhatsApp or chat message.
• Email signature. Add a signature with your photo, title and a link to your full card, so every email carries your details. The email signature generator builds one.
• Social bios. Use your card or profile as the link in your bio.
• NFC tap. Write your card link to an NFC card, tag or sticker, and compatible phones open it with a tap. Support depends on the phone, so keep a QR code as a fallback.

When a QR code will be printed, make it dynamic. A QR code business card with a dynamic code keeps working when your details change, because the printed code points to a short link you control rather than to fixed text.

You capture contacts by letting people share their details back when they open your card. CardDeck shows a short exchange form; when someone fills it in, their contact is saved to your list with the source — which card, QR code, badge or email signature they came from.

This matters because sharing is usually one-way. You give someone your details, and unless they email you, you have no record of them. With contact capture:

• Every new contact arrives with context, so follow-up is specific.
• You can tag contacts (for example by event or product interest) and add notes.
• You can export contacts as CSV or vCard, or to your CRM on Team and Business.

The form records consent with a timestamp, and contacts can be deleted on request.

You manage cards from the CardDeck dashboard: edit details, change the template, see views and scans, and switch cards off. Because every share points to the same live card, one edit updates the card everywhere it has been shared.

For individuals, management mostly means keeping details current and checking which channels work. Analytics show card views and QR scans over time and by channel.

For teams, management happens at the workspace level. Admins can update a locked template once and every member's card follows, see which cards are being opened, and deactivate a card when someone leaves so prospects never reach a dead number.

The four steps are the same for everyone; who does them, and at what scale, changes.

Individuals

You do all four steps yourself. Most people start with one digital business card, add a second for a different role or client sector, and print a dynamic QR code on paper cards or signs.

Teams

An admin sets up the workspace and builds a template with the company logo, colors and fixed fields. Members are invited by email or imported from a spreadsheet, then fill in the fields the admin has opened — usually name, title, phone and photo. The admin sees every card in one list, reviews usage and deactivates cards during offboarding. Teams can also issue employee ID cards from the same records.

Organizations

Schools, colleges, event organizers and membership bodies work in batches. They create a template once per card type — student ID, staff ID, event badge, member card — and generate cards from a list each term, year or event. Each card gets its own QR code; for IDs, scanning opens a verification page that shows whether the card is active.

Your card's QR code should usually be dynamic. A dynamic code holds a short link that redirects to your card, so you can change the card, or even the destination, without reprinting. It also counts scans.

A static QR code stores data directly in the pattern. A static vCard code, for example, contains your name, phone and email as text. It works offline and never expires, but it can't be changed — if your number changes, the printed code is wrong forever. Static codes are useful for things that genuinely won't change, like a WiFi login.

Two practical notes for printed codes: make them at least 2 × 2 cm for scanning at hand's length, and keep a clear margin (the "quiet zone") around them. The ISO/IEC 18004 standard specifies a quiet zone four modules wide.

The batch flow turns a spreadsheet into a set of cards, IDs, badges or codes in one job. It is how organizations do steps 1 and 2 for hundreds of people at once.

1. Prepare the sheet. One row per person, one column per field, headers in the first row. Save as CSV (UTF-8) or XLSX. Give each person a unique ID.
2. Upload and map. Upload the file to the batch generator and match columns to template fields. CardDeck suggests matches from your headers.
3. Add photos. Upload a ZIP of photos named after the ID column; each photo is matched to its row and cropped to fit.
4. Fix flagged rows. Missing photos, duplicate IDs and empty required fields are flagged before anything is issued.
5. Issue or export. Publish digital cards with their own links and QR codes, or export a print-ready PDF (CR80 cards with bleed) or individual files.
6. Update later. Re-import an edited sheet and CardDeck updates existing cards by ID instead of creating duplicates.

Rows per job depend on your plan, from 25 on Free to 25,000 on Business. Answers to common setup questions are in the CardDeck FAQ.
