Guide
Getting Started with NFCKEY
This guide helps you understand how to choose the right setup for NFCKEY — from defining the use case to understanding chip compatibility and design options
What Is NFCKEY?
NFCKEY is a customizable NFC and RFID wearable that can replace physical cards, tags, and keys
It can be used for everything, from simple tap-to-share interactions to secure, system-managed access credentials — all through a quick, contactless tap
What Technology Does NFCKEY Use?
NFCKEY uses NFC (Near Field Communication) and RFID (Radio Frequency Identification) technologies to enable contactless communication between a wearable, smartphone or a dedicated reader
Depending on the setup, a tap can:
- Identify a person or item
- Grant or restrict access
- Open digital content
- Trigger actions in a system
Step 1: Define Your Use Case
Before choosing the chip or the design, start by defining how NFCKEY will be used.
This step focuses on the business goal, not the technology.
Decide on factors like:
- Who will use it?
- What should happen when someone taps NFCKEY?
- Will this be managed by an organization or by an individual?
Common Use Cases
NFCKEY is commonly used for:
- Digital business cards and contact sharing
- Office, gym, or residential access
- Event tickets and visitor badges
- Transport or transit credentials
- Asset tags, staff IDs, and industrial identification

Step 2: Choose The Right Chip
Once the use case is defined, the next step is selecting the correct chip
Not all chips work the same way:
- Some are designed for direct smartphone interactions (e.g. NFCKEY used to replace physical business cards)
- Others are built for secure systems managed by organizations (e.g. NFCKEY used as access cards)
If an organization or system issued the original card, NFCKEY must match that system
Not Sure Which Chip Type You Need?
Option 1: Check The Existing Card With A Smartphone
- You can use the NXP TagInfo app to perform a preliminary check on some cards.
- This may reveal basic information such as the chip family or UID length.
⚠️ Note: Many access credentials expose limited or no information to smartphones.
This method does not confirm system compatibility and should be used as a preliminary check only.
Option 2: Ask The System Administrator
- If you are replacing an access, ticketing or transport card, the system or building administrator can confirm which chip type is required.
This is often the fastest and most reliable option.
Option 3: Demo & Testing Of NFCKEY Technical Packs
- Order our Technical Packs to test compatibility before committing to full production
Step 3: Pick Your Design
Once the chip type and functionality are confirmed, you can choose how your NFCKEY looks
Design Options
Ready-Made Designs
Choose from a selection of pre-designed NFCKEY wearables
This option is suitable if:
- You do not require custom branding or visual changes
- You want a straightforward, ready-to-use design
We offer designs with various themes, from fun Sushi collections to more serious Energy collections
Custom Designs
If you want NFCKEY to reflect your brand or visual identity, you can create a fully custom-designed wearable
Custom designs allow you to:
- Apply your own branding, colours, and graphics
- Match the wearable to your brand, event, or environment
The chip, functionality, durability, and performance remain the same as ready-made designs — only the appearance changes
With the use case, compatibility, and design defined, you’re ready to move forward — either by exploring chip specifications, reviewing industry examples, or testing compatibility before production.
