NFC Promotional Items: How the Chip Works

You’re holding a pen in your hand. Your smartphone is lying next to it. You tap the smartphone briefly against the pen. A website opens. Done. No scanning. No app download. No PIN.

That’s exactly what NFC is. And that’s exactly what makes smart giveaways so effective. But how does it work technically? What’s inside the pen? And why does your customer need zero preparation for it?

This article answers these questions. Step by step, no shortcuts.

What’s Actually Inside an NFC Giveaway?

NFC stands for Near Field Communication. The technology transmits small amounts of data over a maximum distance of 4 centimetres. That’s no coincidence. This short range is a security feature.

At the core of an NFC giveaway sits a tiny chip with an antenna. The chip is typically the size of a small postage stamp. It uses no battery. It requires no external power supply. The energy for data transfer comes directly from your smartphone’s electromagnetic field at the moment of contact.

In technical terms, this is called a “passive tag”. Passive means: the chip does nothing until an active device (your phone) activates it. It simply sits inside the pen, waits, and transmits its content as soon as a smartphone comes close enough.

What’s Stored on the Chip?

Usually a URL. A web address. Nothing more.

The standard chip for giveaways is called NTAG213. It holds 144 bytes of storage. That sounds like very little, but it’s more than enough for a complete URL. For 95% of all applications in the promotional products world, this chip is exactly right.

What can a chip contain?

A URL (most common)
A digital business card (vCard)
Wi-Fi credentials
An app store link
A short text

What’s not included: personal data about the user. The chip stores no information about the person who taps it. It only sends, it doesn’t receive. This matters for data protection, more on that shortly.

Why Doesn’t the Recipient Need an App?

This is the most frequently asked question when companies first hear about NFC giveaways. The answer is clear: because NFC has been natively built into smartphones for years.

As of 2025, over 85% of all smartphones worldwide have NFC integrated. The NFC Forum (the international non-profit organisation that defines NFC standards) confirms this in their latest analysis.

In practical terms, this means:

iPhone 7 and newer with iOS 13+: NFC tags are recognised automatically, no app download required
Android from version 4.4: NFC natively activatable, enabled by default on virtually all current devices
Samsung, Google Pixel, Huawei, Xiaomi: all major manufacturers support NFC

What happens technically in that moment? The operating system detects the NFC tag, reads the stored URL and opens it automatically in the browser. No intermediate step. No waiting screen. No login.

That’s the decisive difference from earlier smart technologies. Bluetooth beacons required an app. RFID readers required special hardware. NFC uses the hardware that’s already in every jacket pocket.

How Does NFC Compare to QR Codes?

QR codes also work without an app, but with more effort. You have to open the camera, align it, and wait for the code to be recognised. That’s three steps instead of one.

Avery Dennison, the world’s largest manufacturer of NFC tags, measured in field studies: NFC achieves 3 to 5 times higher usage rates than QR codes in comparable settings. The reason is friction. Every additional step costs users. NFC has the lowest barrier of all available technologies.

94% of marketers use QR codes in campaigns. That shows how widespread the standard is. And that’s exactly why NFC is the next logical step: same function, less friction.

The Technical Process in Three Steps

So you can think through the principle completely, here’s the full technical process from start to finish.

Step 1: Production of the Giveaway

An NFC chip (e.g. NTAG213) is either embedded directly into the product or applied as a sticker onto the product. In an NFC pen, the chip sits inside the casing, invisible. In an NFC sticker, it sits directly beneath the surface.

Before the product is shipped, the chip is “programmed”. This means: the URL is written onto the chip. Either directly (static tag) or via a redirect system (dynamic tag).

The difference between static and dynamic is practically relevant: with a dynamic tag, the chip points to an intermediate page. This intermediate page redirects to the actual target URL. This allows you to change the target URL at any time without ordering new giveaways.

Step 2: Activation by the Smartphone

The recipient’s smartphone comes within 4 centimetres of the chip. The operating system detects the near-field signal and reads the tag. This happens in milliseconds.

On iPhones, a small banner appears at the top of the display. On Android, the browser opens directly or a confirmation prompt appears. In both cases: the user lands on the stored page.

Step 3: Tracking and Evaluation

On the landing page, the actual marketing begins. When you include UTM parameters in the URL (these are tracking additions that tell your analytics tool where the visitor came from), you can see in Google Analytics or your CRM (Customer Relationship Management, meaning your customer management system):

When the tap occurred
Which device was used
Which campaign triggered the tap
What the user did on the page after tapping

That’s the fundamental difference between a classic promotional item and an intelligent giveaway. The pen at 80 cents disappears into a drawer. The NFC pen at CHF 4.50 delivers data you can actually work with.

Data Protection: What the NFC Chip Knows About the User

The short answer: nothing.

An NFC chip transmits information, it doesn’t receive any. It stores no device data, no location data, no personal information about the user. The chip contains only what you wrote onto it during programming. Typically a URL.

GDPR relevance (GDPR stands for General Data Protection Regulation, the European data protection law) only arises on the linked landing page. That is, where analytics tools run or forms are filled in. That’s the same legal situation as with any normal website.

Switzerland’s Federal Act on Data Protection (FADP, in force since September 2023) is largely aligned with the GDPR. If you have a GDPR-compliant landing page, you’re on safe ground under Swiss FADP as well.

Important: this standard applies to all interactive promotional items that rely on analytics. Not just NFC products. The technology itself raises no data protection concerns.

What NFC Giveaways Mean for Your Marketing in Practice

Understanding isn’t enough. What counts is what you do with it.

An NFC giveaway is not a technical toy. It’s a measurable marketing instrument. According to McKinsey, customers who interact with a brand through phygital touchpoints (the points of contact between the physical and digital world) spend an average of 30% more and show 23% higher brand loyalty.

That’s no coincidence. A phygital giveaway doesn’t stop working when the trade show is over. Every time someone picks up the NFC pen and taps it, that’s a new touchpoint. Weeks or months after the first contact.

A Concrete Calculation Example

You take 200 NFC pens to a trade show. Cost: 200 x CHF 4.50 = CHF 900.

Avery Dennison measures tap rates of between 15% and 30% for actively communicated NFC tags (with instructional text on the product). Let’s take 20%. That’s 40 taps.

If 25% of those taps fill in a contact form, you have 10 qualified leads. Cost per lead: CHF 90.

For comparison: the average cost per lead for Google Ads in B2B in Europe is between EUR 50 and EUR 200, depending on the industry. And those 10 leads from the NFC pen can keep tapping for months after the trade show.

Note: without instructional text on the product, the tap rate drops below 5%. A simple NFC icon and the text “Tap here” triples the usage rate. That’s not a technical question. It’s a communication question.

Three Mistakes to Avoid From the Start

Mistake 1: Using the homepage as the target URL. The homepage is for everyone. A dedicated landing page is for the person currently holding your pen. Create a specific page for the campaign.

Mistake 2: Not adding UTM parameters. Without UTM parameters, you’ll know someone tapped, but not when, where or via which giveaway. A URL like ?utm_source=trade-show-zurich&utm_medium=nfc&utm_campaign=autumn25 gives you complete data.

Mistake 3: Choosing static tags for dynamic campaigns. If your landing page changes (new campaign, new offer), you’ll need to order new giveaways with static tags. With dynamic tags, you change the destination in a dashboard. The physical item stays unchanged.

FAQ: How NFC Giveaways Work

Does the recipient need a special app to use an NFC giveaway?

No. Smartphones from iPhone 7 with iOS 13 and virtually all current Android devices read NFC tags without an app. The operating system automatically recognises the chip and opens the stored URL in the browser. That’s the biggest advantage over older technologies that required an app download.

How close does the smartphone need to be to the NFC chip for it to work?

The maximum range is 4 centimetres. In practice, it works most reliably at direct contact or within a few millimetres. This short range is not a disadvantage but a security feature: the tap only happens when the user intentionally triggers it.

Can I change the content of an NFC giveaway after production?

With dynamic NFC tags: yes. You change the target URL in a dashboard, the physical tag remains unchanged. With statically programmed tags: no. For promotional items, we always recommend dynamic tags, because you can then adjust campaigns, run A/B tests and update content without ordering new items.

Is an NFC giveaway GDPR-compliant?

Yes, when used correctly. The NFC chip itself stores no user data. It only contains the stored URL and transmits it passively. GDPR relevance only arises on the linked website, where analytics or forms are active. That’s the same legal situation as any other website visit.

What does an NFC giveaway cost compared to a classic promotional item?

An NFC pen starts from CHF 4.50, a classic pen from around CHF 0.80. The price difference is approximately CHF 3.70 per unit. This premium pays off quickly: at a 20% tap rate on 200 units, you get 40 taps. If 25% of those taps convert to a lead, each lead costs CHF 90. In B2B Google Ads, you’d pay at least twice that.

Which NFC chip standard is right for promotional items?

For 95% of all promotional item applications, NTAG213 is the right standard. It has 144 bytes of storage, which is more than sufficient for any URL. It’s cost-effective to produce, compatible with all common smartphones and fully adequate for straightforward tags. More complex applications such as multi-level data structures may require NTAG216 with 888 bytes of storage.
