RFID vs. QR Code – Which Access Method Suits You?
When looking into digital access systems, you quickly encounter various technologies. In this article, we focus on the two most relevant options in practice: RFID and QR code.
What Is RFID?
RFID (Radio-Frequency Identification) enables contactless identification via radio waves. In access control, RFID is typically used via cards, wristbands or chips – fast, offline-capable and ideal for fixed user groups.
What Is QR Code Access?
With QR code access, users receive an individual code via email, SMS or app and scan it at the reader. No physical medium needed – perfect for guests, delivery drivers and changing users.
RFID vs. QR Code Compared
- Medium: RFID = card/wristband · QR code = digital on smartphone
- Distribution: RFID on-site · QR code remote via digital delivery
- Cost per user: RFID ~€1–3 per card · QR code free
- Offline capability: RFID yes · QR code often requires internet
- Flexibility: QR code time-limited and changeable anytime
Which Method for Which Use Case?
- RFID: gyms, companies with permanent staff, sports facilities, tool distribution
- QR code: coworking spaces, hotels, vacation rentals, parcel handover, temporary visitors
Frequently Asked Questions
Can I combine RFID and QR code?
Yes – the TIKI SHARE platform supports RFID, QR code, PIN and other methods in parallel and per user.
Which is more secure – RFID or QR code?
Both are secure when implemented correctly. RFID cards are hard to clone, and QR codes can be time-limited or issued as single-use codes.
What fits guests in vacation rentals?
For short-term access, QR code is fastest – the code is sent digitally, without handing over a card.
