Brand identity on a custom digital business card: logo, colours, type and tone

Brand identity on a custom digital business card: logo, colours, type and tone — Online Business Cards

By Online Business Cards Editorial Team | Published | Updated | Setting up your card

A custom digital business card is often the first place someone meets your brand on a phone. Here is the small brand kit to prepare, and how to apply each part so the card looks and sounds like you.

For many small businesses, a digital business card is where people first meet the brand on a phone, before they ever see the website. If the card uses your real logo, your colours and your way of speaking, it does more than pass on a phone number. It tells people who you are.

This guide is about brand identity: the look and voice that make your business recognisable. It covers what to prepare and how to apply it. For the editor's settings, see our guide to customising your digital business card.

Start with a small brand kit

You do not need a brand book. You need six things in one folder before you start.

1. Logo files

  • A square version, for the profile picture spot, with some space around the mark so it is not cropped.
  • A wide version, if your logo has one, for headers.
  • High-quality files: a PNG with a transparent background is the safest choice. Check which formats the editor accepts.

If your logo only exists as a blurry image from an old website, it is worth asking whoever designed it for the original files.

2. Colour codes

Write down the exact codes for your main colours, usually as hex codes such as #2A3CC0. Guessing by eye gives you a slightly different blue on every platform. If you do not have codes, take them from your website's style settings or ask your designer.

3. Type

Note the typefaces your brand uses. Editors usually offer a set of web fonts rather than any font you like, so pick the closest match. Readability on a phone matters more than an exact match.

4. Photography style

Decide what your photos look like: bright and natural, or dark and moody; people or products; indoors or out. Then choose a profile photo, a cover image and a handful of gallery images that all fit that style.

5. Tone of voice

Write three words that describe how you sound, such as "warm, plain, practical" or "precise, calm, expert". Then check every line on your card against them, from your headline to your button labels.

6. Your key line

One sentence that says what you do and for whom. It should match the line on your website and your social profiles.

Applying your identity to the card

Choose a template that suits the logo. A detailed logo needs a calm layout; a simple logo can take a bolder one. Try your logo on two or three templates before deciding. Use your colours with restraint. One main colour for buttons and headings, plus a neutral background, usually looks more confident than every brand colour at once. Check the contrast. Text and buttons must be easy to read. The Web Content Accessibility Guidelines ask for a contrast ratio of at least 4.5 to 1 for normal text. Pale brand colours often fail this as button backgrounds, so use them for accents instead. Our accessibility guide explains how to check. Keep your logo small and sharp. It should be recognisable, not dominant. The person's name, or the business name, and the main button matter more. Write button labels in your voice. "Book a fitting" says more about a bridal shop than "Contact".

Personal card or business card?

If the card is for one person, lead with their photo and name, and use the logo as a supporting element. People connect with people. If the card is for the whole business, lead with the logo and the key line, and add a team photo in the gallery.

One brand everywhere: a consistency check

Your card is one of several places people meet your brand. Run this check across all of them.

Step 1: list every place people find you

Write down everywhere your business appears. For most small businesses, the list looks something like this:

  • your digital business card;
  • your website, including the contact page and footer;
  • your email signature;
  • LinkedIn, Instagram, Facebook, TikTok or other social profiles;
  • your Google Business Profile and any review sites;
  • directory listings and trade association pages;
  • printed material, such as paper cards, flyers or van signs;
  • invoices, quotes and proposal templates.

Open each one in a browser tab. Seeing them side by side is the quickest way to spot differences.

Step 2: check the details that must match exactly

Some details should be identical everywhere. Go through each place and check:

Detail | What to check

Business name | Spelt the same way everywhere, including "Ltd" or "&"

Main phone number | One main number, written the same way

Main email address | One address, not a mix of old and new

Address or service area | Matches your Google Business Profile

Opening hours | Up to date, including holidays

Website address | Correct, with no old domains

These are the details people act on. A wrong number or old email address costs you enquiries, and mismatched names or addresses can confuse people searching for you. If you run a limited company, there are also rules about showing your registered details; our startup set-up guide explains them.

Step 3: check the details that should look the same

Other details do not need to be identical, but should clearly belong together.

  • Logo. Use the same version everywhere. If you have a full logo and a small icon, decide where each one goes.
  • Colours. Note your main brand colours as colour codes, so whoever updates your website or designs a flyer uses the same shades.
  • Photo. Use the same recent headshot on your card, LinkedIn and email signature, so people recognise you. Replace it everywhere at once when you update it.
  • Fonts. If your website uses a particular typeface, use it on printed material too. On your digital card, choose a template that sits comfortably with your brand.

Step 4: line up the words

Your headline and short description should say the same thing everywhere, even if the length varies. Write one master version:

  • One line: what you do and who for, such as "Chartered accountant for sole traders and landlords".
  • One paragraph: 40 to 80 words with a little more detail.

Use the one-line version for your card's headline, social bios and email signature, and the paragraph for your card's bio and the About section of your profiles. Our guide to writing your card's headline and bio has examples.

Check your main call to action too. If your card says "Book a free call" but your website says "Request a quote", decide which you prefer and use it in both places.

Step 5: make your card the hub

Your digital business card is a useful place to bring everything together, because its link stays the same when you edit it. Once your card is correct:

  • add your card link to your email signature;
  • put it in the bio or website field on your social profiles;
  • print its QR code on paper material; our guide to QR codes on printed cards covers this;
  • link it from your website's contact page.

Then, when a detail changes, you update the card first. Everyone with your link or a printed code sees the new details straight away, and you can work through the other places on your list.

Step 6: write a one-page brand sheet

Put the results on a single page so you, a colleague or a designer can get it right next time. Include:

  • your business name exactly as it should appear;
  • main phone number, email address and website;
  • logo files and where to find them;
  • brand colour codes;
  • your one-line and one-paragraph descriptions;
  • your main call to action;
  • your card link and where its QR code file is saved.

Keep it somewhere easy to find, such as a shared folder.

For teams: same brand, different people

If several people have cards, keep the business details the same and let personal details vary:

  • Shared: business name, logo, colours, company description, website and main office details.
  • Personal: name, photo, job title, direct phone number and personal LinkedIn.

Decide who can change the shared details, and agree what happens when someone joins or leaves. Our guides for startups and small teams and sales teams cover team set-up.

Step 7: check again every few months

Details drift. Someone updates the website but not the Google profile, or a new photo goes on LinkedIn but not the card. Put a reminder in your calendar every three months, or whenever something changes, such as a new number, a move or a new service, and run through your list again.

Common slips to look out for

  • An old mobile number still on a directory listing.
  • A personal email address on one profile and a business one elsewhere.
  • Opening hours that were never updated after a change.
  • A logo from before a redesign on printed material or invoices.
  • Different job titles on your card and LinkedIn.
  • Old links in social bios that point to a page that no longer exists.

When your work is the brand

For photographers, designers, illustrators and other creatives, the work itself is the identity. Your gallery carries more weight than your logo, so choose fewer, stronger pieces and keep image quality high. Our guide for photographers, designers and other creatives covers portfolios, permissions and rates.

Common mistakes

  • a stretched or blurry logo
  • colours that look nearly, but not quite, like your website
  • three or four different typefaces
  • a cover image that has nothing to do with the business
  • a tone that changes between the headline and the bio

Which plan you need

Frequently asked questions

How do I put my brand identity on a digital business card?

Prepare your logo files, colour codes, type, photos, tone of voice and a key line. Then choose a template that suits your logo, use one main colour for buttons and headings, check the contrast and write every label in your brand's voice.

What logo file should I use on a digital business card?

A high-quality PNG with a transparent background is usually safest. Use a square version, with space around the mark, for the profile picture, and check which formats the editor accepts.

Should my digital business card match my website?

Yes. Using the same logo, colours and key line on your card, website, email signature and social profiles helps people recognise you.

Can I use my brand colours if they are pale?

Yes, but use pale colours for accents rather than text or button backgrounds, where they may not have enough contrast to be easy to read.

Which details must be the same everywhere?

Your business name, main phone number, main email address, address or service area, opening hours and website address. These are the details people act on.

How do I keep a team's cards consistent?

Keep business details shared and identical, let personal details such as name, photo and job title vary, and agree who can change the shared details.

How often should I check my branding?

Every three months is a sensible routine, plus whenever something changes, such as a new phone number, a new photo, a move or a new service.
