A paper business card goes into one hand at a time. A digital name card is a page, and the QR code or NFC tap that opens it can end up in places you never planned: a screenshot forwarded to a group chat, a sign on the counter read by every customer who walks past, a flyer left on a table. So the question is not only what to put on the card. It is which details you are happy for a stranger to have, and for how long.
This guide is a privacy-minded field checklist for owners and staff who are about to share a QR code. It covers work numbers against personal mobiles, home addresses, links, photos and printed material, and it ends with a ten-minute check you can run before the code goes anywhere public. It is general good-practice advice, not legal advice, and it does not describe any privacy setting on the platform. It relies only on what the share2.io platform is listed as doing: cards are editable and shared by QR code or NFC tap. It is not about which fields to put first to get people to contact you. For what happens when someone leaves, see what happens to a digital name card when an employee leaves, and for how the card sits beside a professional profile, see digital name card vs LinkedIn.
Why a digital name card needs a stricter rule than paper
With a paper card you decide, one handshake at a time, who gets your details. A digital name card changes four things at once, and each one is a reason to be more careful about what goes on it.
- Reach. A QR code on a counter sign, flyer, badge or email signature is seen by everyone who sees that item, not only the people you chose to hand it to.
- Copies. A screenshot, a forwarded link or a photo of the code can travel on without you knowing. You cannot recall any of them.
- Saved contacts. When someone saves your details, the copy lives on their phone. You can edit your profile afterwards, but you cannot edit their copy.
- Lifespan. A card handed out once is forgotten. A saved contact or a code printed on a banner can stay in circulation for years.
The sensible rule follows from that. Treat everything on the card as visible to anyone who gets the QR code or the link, and decide field by field whether you are comfortable with that.
A three-question test for every field
Before you add a detail, ask three questions. If the answer to any of them is no, leave the detail off or swap in a work equivalent.
- Would I say this out loud to a stranger at a stall? If you would hesitate to read it aloud, you should hesitate to publish it.
- Does someone need it to deal with me about work? A detail that is merely convenient for you is not a reason. A detail a customer needs to reach you is.
- Would I be comfortable with it still being visible, saved on phones and passed around in a year? This is the question that catches personal numbers and addresses, because they are the details that are hardest to take back.
Most cards pass the test with no trouble: name, role, company, a work email, a work number and a website. The trouble is almost always in the two or three extras added because the form had a box for them.
Field by field: what belongs and what does not
Use this table as a starting point and adjust it for your own business. The right-hand column gives the reason, or a safer alternative where one exists.
| Detail | Verdict | Reason, or a safer alternative |
|---|---|---|
| Your name and job title | Include | This is what a card is for. Use the name you trade under |
| Company name and logo | Include | It tells the contact who you represent |
| Work email | Include | Prefer a work or shared mailbox to a personal inbox that also receives bills and family mail |
| Work phone or work WhatsApp number | Include, if separate from your personal line | It is the most used contact detail, so it is the one most worth keeping apart from your private number |
| Personal mobile number | Leave off, unless it is also your only work line | Once saved on other people's phones it cannot be taken back. See the next section for options |
| Business or office address | Include only if customers are meant to visit | Useful for a shop or showroom, irrelevant for a business that works online or at the client's site |
| Home address | Leave off | No contact needs it. For a home-based business, give an area or "by appointment" instead |
| Website and booking or enquiry link | Include | It moves people to a page you control and can keep current |
| LinkedIn or other professional profile | Include, once you have checked it | Open it as a stranger would and see what it shows publicly |
| Personal Facebook or Instagram | Leave off, unless it is run as a business account | Family photos, tagged places and old posts belong to your private life |
| IC or passport number, bank or payment details | Never | No business reason puts these on a page anyone can open. Send payment details on an invoice to the one customer |
| Date of birth and family details | Never | They add nothing to a business contact and are useful to the wrong people |
| Profile photo | Optional | A plain work portrait helps people recognise you. Avoid backgrounds that show your home, your children or other people |
| Working hours | Include | A line such as "Mon to Fri, 9am to 6pm" sets expectations and protects your evenings |
Two rows deserve more space, because they are where most owners and staff are unsure: the personal mobile number and the home address.
The personal mobile number: the hardest call
Many Malaysian owners and sales staff run everything from one phone. That makes the personal number the obvious thing to put on the card, and the thing most people later wish they had not. Once it is saved on a stranger's phone, it can receive calls and messages at any hour for as long as you keep the number.
| Option | What it protects | The trade-off |
|---|---|---|
| Put the personal number on the card anyway | Nothing, but it is the simplest to set up | Everyone who saves it has your private line, and it is hard to retire later |
| A separate work number or a WhatsApp number used only for work | Your private number stays private, and the work number can be replaced or handed over | A second SIM or phone to look after, and one more number to keep current |
| Email plus a booking or enquiry link, with no number shown | No number is exposed at all | Slower for people who prefer to call. Works best when most of your work arrives as appointments or enquiries |
| A shared company line, such as a sales or reception number | The number belongs to the business, so it survives staff changes | Someone has to answer it and pass messages on |
If your personal number is already your public business line and is printed and saved all over town, you do not need to panic. Decide whether it stays as your work number from now on, and keep the rest of your personal details off the card. If you are staff rather than the owner, ask your employer before putting a personal number on a company card. Many businesses prefer a company number, so that the contacts stay with the business. That also saves an awkward clean-up when someone moves on.
Home address, location and the links behind your card
Many Malaysian businesses start at a kitchen table or a spare room. A card that shows a home address tells every reader where to turn up. Show an address only if customers are meant to visit. If they are not, use one of these instead:
- An area, not an address. A town or a service area tells a customer whether you cover them without telling them where you live.
- "By appointment". Share the exact address in a message after the booking is made, not on a page anyone can open.
- A meeting or pick-up point. A map link to a public place keeps the location useful and your home private.
- The business address only. If your registered business address is also your home, ask whether you would be comfortable seeing it on a flyer. If not, leave it off the card.
A card is also a doorway, because every link on it opens something else. Open each one from a second phone and ask what a stranger can see there. A personal Facebook page with family photos, a public Instagram account with tagged places, a shared folder that was never locked down, or a calendar link that shows the titles of your other appointments can undo all the care you took with the card itself. The same goes for the bio and notes fields: a line such as "call me any time" next to a personal number sends exactly the wrong message.
The printed card is where mistakes stick
The profile behind the QR code is editable. Anything printed is not. The physical NFC card options, Design-Ready and Custom-Design, include printing, and a flyer, banner or badge works the same way: whatever is written on it stays until it is reprinted. Our guide to editing a digital name card after printing explains why the profile can change while the printed piece cannot.
The practical rule is to print as little as possible. A name, a company and the QR code or a tap prompt is enough, because the details sit in the profile, where you can change or remove them. Printing a personal number or a home address on the face of a card puts the one thing you cannot edit in the place most likely to be photographed and passed on.
The second rule is about public placement. A QR code on a counter sign, a window or a flyer can be scanned by anyone who sees it, so the profile behind a public code should hold only details that are fit for the public. If you want to give a few clients a fuller set of details, send it to them directly rather than putting it behind a code on the wall. Before a code goes on anything printed, scan a printed proof on two or three phones, and read the page it opens from top to bottom.
One profile, several profiles, or a team
The share2.io plans cap profiles and QR codes separately: the Free plan covers 3 profiles and 3 QR codes, Pro covers 15 profiles and 30 QR codes, and Team covers 50 profiles and 100 QR codes. That has a privacy use, because more than one profile lets you offer different sets of details to different audiences. For example, you could keep a lean profile for signs and flyers and a fuller one that you share only person to person. Keep one caution in mind: a profile is still visible to anyone who is given its code or link, so the fuller one should still be treated as something that can be forwarded.
For a team, the owner should set the rule once rather than leave each person to guess:
- Agree an approved list of fields. For example name, role, company, work email, company or work number, website. Everything else is optional and needs the person's consent, and nothing personal is added by default.
- Use company numbers for company cards. A staff member who prefers to use a personal phone should be asked, not assumed, and the choice recorded.
- Review every profile before its code is shared. One person, usually the owner or a manager, reads each profile as a stranger would.
- Add a privacy line to the regular review. Our quarterly checklist for keeping a digital name card up to date is the natural place for it.
- Plan for leavers. A card with a personal number on it is harder to hand over than one with a company number.

What removing a detail does, and does not, undo
Because the profile is editable, a detail you regret can be removed. That fixes some things and not others, so the safest time to decide is before you share.
| Situation | Does editing the profile fix it? |
|---|---|
| Someone scans your QR code next week | Yes. They open the profile as it is now |
| Someone saved your contact last month | No. They keep the copy on their own phone. If a number has changed, tell important contacts directly |
| A screenshot of your card went into a group chat | No. The screenshot shows the old version |
| A detail is printed on a card, flyer or banner | No. It stays until the item is reprinted |
| A link on the card leads to a page you no longer want public | Not by editing the card alone. Fix the page the link opens, or remove the link |
If you do remove a personal number, remember it only affects what future visitors see. The people who already have it can keep using it.
A ten-minute check before you share the code
Run this before the code goes on anything public, and again after any big edit. Use a second phone, not the one you edit on.
- Scan the code and read the whole profile as if you were meeting yourself for the first time.
- Tick off each detail against the three questions from earlier. Remove anything that fails.
- Tap every number, email and link and look at what each one opens. Check what a stranger can see on that page.
- Save the contact to the phone and read the saved copy. That is what the other person keeps, so check that it matches what you meant to share.
- Look at the photo and the bio for anything that gives away a home, a school, a car or a routine.
- Check printed material against the profile, so nothing personal is printed that you have since removed.
- Ask one colleague or friend to scan it and tell you what they notice. A fresh pair of eyes finds what you stopped seeing.
Ten minutes here is cheap. Taking a number back from a hundred phones is not possible.
Common mistakes
- Adding every field because there is a box for it. A field being available is not a reason to fill it.
- Treating the card as private. It is a page reached by a code, so anyone with the code or link can see it.
- Using the personal number by default. Decide on a work number first, then add it.
- Showing a home address on a home-based business. Use an area or "by appointment".
- Forgetting where the links go. A clean card that links to an open personal profile is not clean.
- Printing what you cannot edit. Keep personal details out of printed pieces and in the profile.
- Assuming an edit reaches saved contacts. It does not. People keep their own copy.
- Letting each staff member decide alone. One approved list keeps every card consistent and safe.
- Never checking again. Roles, numbers and links change, so repeat the check at each review.
Where Gotka Technologies fits
Gotka's Digital Name Card service runs on the share2.io platform, where subscription plans and card options are ordered at share2.io/shop. Cards are editable and shared by QR code or NFC tap, which is why you can start lean, check the result on a second phone and adjust before the code goes anywhere public.
You can start on the Free plan, which covers 3 profiles and 3 QR codes, with Digital Only: Self Setup at RM0. If you would rather have the profile designed for you, Digital Only: We Design is RM48, and a physical NFC card comes with Design-Ready at RM118 or Custom-Design at RM338. If your card points to a website, make sure that page is also safe to share. Gotka's web design service runs from design through ongoing maintenance.
Key terms used in this guide
- Digital profile: the page people see after a scan or tap, holding your contact details and links.
- QR code: a square code that a phone camera scans to open your profile. Anyone who sees the code can scan it.
- NFC card: a physical card that opens your profile when held against a compatible phone. It opens the profile rather than storing your details.
- Work number: a phone or WhatsApp number used only for business, kept apart from your private line.
- Saved contact: the copy of your details a person keeps in their own phone after scanning or tapping. Editing your profile does not change it.
- Approved field list: the short list of details a business allows on every staff card.
- Printed proof: a test print of a QR code or card, scanned on real phones before a full print run.
- Second-phone test: opening the card from a phone you do not edit on, to see what a visitor sees.
Should I put my personal mobile number on my digital name card?
Usually not. Once a personal number is saved on other people's phones you cannot take it back, and it can receive calls and messages at any hour. Use a work number or a WhatsApp number kept for business if you can. If your personal number is already your only business line, decide whether it stays as the work number and keep your other personal details off the card.
Is it safe to put my home address on a digital name card?
It is better to leave it off. A home address tells every reader where to turn up, and no contact needs it to deal with you. If you work from home, show an area or a line such as by appointment, and share the exact address in a message once a visit is agreed. Show a business address only if customers are meant to visit.
Who can see what is on my digital name card?
Treat the card as visible to anyone who gets the QR code or the link. A code on a sign, flyer or email signature reaches everyone who sees it, and a link or screenshot can be forwarded. This guide gives general good practice and does not describe any platform privacy setting, so put on the card only what you would be comfortable giving to a stranger.
Can I remove a detail from my digital name card after sharing it?
Yes, the profile is editable, and anyone who scans afterwards sees the updated version. But people who already saved your contact keep their own copy, screenshots keep the old version, and anything printed stays until it is reprinted. That is why it is safer to decide before you share, and to tell important contacts directly if a number changes.
What details should never go on a digital name card?
Leave off your IC or passport number, bank or payment details, date of birth, family details and personal social media accounts. None of them helps a business contact, and all of them can be used by the wrong person. Send payment details on an invoice to the one customer instead, and keep private accounts and family photos off every link on the card.
What should staff put on a company digital name card?
Name, role, company, a work email, a company or work phone number and the website, drawn from an approved list the business sets once. A personal number goes on only if the person agrees, and that choice should be recorded. The owner or a manager should read each profile as a stranger would before its code is shared, and recheck it at each review.
