NFC Business Cards for Companies: How They Work, How Long They Last, How to Choose

A company NFC card is the size of an ordinary business card, with a small chip and antenna inside and no battery. When an employee holds it near a customer’s phone, their digital business card opens in the browser straight away — name, title, numbers and the company logo — and the customer saves the contact in one press. The chip holds one link only, not the employee’s details, which is why the card stays valid for years however much the details behind it change.

How does an NFC card work?

The phone creates a small magnetic field around itself. When the card enters it — a few centimetres away — its antenna picks up a tiny current, enough to wake the chip; the chip sends the stored link, and the phone shows a notification that opens the page. No button, no charging, no app on either side.

The short range is deliberate: nobody reads your card from across the room. For the technology itself, see what NFC is and how it works.

Which phones read an NFC card?

• iPhone XS and later: reads the card automatically while the screen is on, with no setup.
• iPhone 7 to X: reads through the “NFC Tag Reader” in Control Center.
• Most recent Android phones: reading is on by default on most; if not, Settings → Connections → NFC.

That is why every card carries a QR code on the back that opens the same card: if the customer’s phone is old or NFC is switched off, the camera is enough.

How long does an NFC card last?

The answer comes in two parts, because a card is two things:

The chip: NXP rates its common NTAG21x chips for ten years of data retention and a hundred thousand write cycles, according to its datasheet. Reading does not wear the chip: a card tapped thousands of times is not weakened by the taps.

The body: this is what actually wears. Print fades from rubbing in a wallet, and a card snaps if it is bent hard across the antenna. A card’s practical life is set by its body and how it is used, not by its chip.

What never ends a card’s life: a new number, a new title or a new company logo. All of those change on the digital card, and the link on the chip stays as it is.

How to choose NFC cards for your team

Material:

• PVC (plastic): the most common, light, and fully printable. Right for most teams.
• Wood: a different look and a natural feel; needs more care with moisture.
• Metal: heavy and premium, but metal blocks the NFC signal. Good metal cards put the chip in a non-metal window or over an insulating layer; ask the print shop to test a read in front of you before the full order.

Chip: a card link is short, so an NTAG213 is enough. NTAG215 and NTAG216 hold more, which one link does not need.

Design:

• The company logo and colours on the front, and the employee’s name if you want personal cards.
• The card’s QR code on the back as a fallback.
• A small mark showing where to tap, because many customers do not know where to hold the phone.

Where to get the cards, and how they are programmed

Order employee cards from any print shop that makes NFC cards: give them your design and each employee’s card link, and they program each chip with its link. Or buy blank cards and write the link yourself with an NFC writing app on your phone — it takes seconds.

In AurCard every employee card has a permanent link from the moment it is created, so you can program the card on day one and let the employee complete their card later. For shopfronts, AurCard sells the smart sticker from the dashboard for 74.75 SAR including VAT, for the door, the table or next to the till.

After programming you can lock the chip so nobody can rewrite it. Locking is permanent: do not lock a card you plan to reprogram for another employee later.

What happens to the card when an employee leaves?

This is where a card that holds a link beats a card that holds data. In AurCard, stopping an employee’s card is one press: its link then answers with the company page, their access to the customer ledger and conversations ends, and the numbers they collected stay with the company.

And the card in their pocket? Anyone who taps it afterwards reaches your company page, not the number of someone who no longer represents you. If you get the card back and did not lock it, reprogram it with the new employee’s card.

Where does your team use an NFC card?

At the first meeting. Instead of dictating a number or hunting for a card in a wallet, the employee holds the card near the customer’s phone and the customer saves the contact before they sit down. The first impression is part of the service here.

At an exhibition. Hundreds of short meetings in one day. A tap takes two seconds, and every number a visitor leaves on an employee’s card goes into the company’s customer ledger under the name of whoever collected it — so after the show you know who collected what, instead of a pile of paper cards on a desk.

On field visits. Sales reps, technicians and site engineers meet customers at their door. The card leaves them a page with the company’s number, WhatsApp and services, not the number of a person who may change.

At reception. A card on the front desk, or a sticker beside it, opens the company page itself, so a visitor saves the number while waiting.

In every case, a manager sees in the analytics how often each employee’s card was opened and saved, and knows which meeting paid off.

NFC card, QR code, or both?

A tap is faster face to face and leaves an impression. A QR code works at a distance, with any phone, and prints on anything. Both on one card cover every case, which is why we always recommend both. NFC cards for your team are on the NFC cards page, and managing employee cards in the company identity is under team management.

Frequently asked questions

Does an NFC card need a battery or charging?

No. The chip draws its power from the phone’s field at the moment of reading and needs no battery or charging.

Does the customer need an app to read an NFC card?

No. Modern phones read the card and open the link in the browser directly. iPhone 7 to X read it through the NFC reader in Control Center.

Can someone steal an employee’s data from an NFC card?

The chip holds the link to their public card only — what you would hand anyone on a paper card. It holds no bank data or passwords, and its range is a few centimetres.

Do I need a new card if an employee’s number changes?

No. The number changes on the digital card, and the link on the chip stays the same.

Do metal cards work?

They do if they are designed for it, with the chip in a non-metal window or over an insulating layer. Test a read on an iPhone and an Android phone before ordering the full quantity.
