Access Control Compared – RFID, QR Code or Smartphone?
RFID, smartphone, QR code or PIN – an honest comparison of common access methods and which one fits your use case.
The Four Common Access Methods
RFID cards are the classic: fast, robust, work offline. But they need physical issuance and replacement on loss. Smartphone access is convenient but requires a charged device and – depending on the system – an installed app.
QR codes are ideal for short-term or one-off access: sent instantly, no handling. PINs work everywhere but are the least secure because they can be shared.
Which Method for Which Case?
- Long-term members (gym, coworking, office): RFID + smartphone
- Guests and contractors: QR code or time-limited PIN
- Holiday rentals and hotels: QR/PIN complemented by smartphone
- Critical areas: 2-factor (RFID + PIN, smartphone + biometrics)
- Public rental stations: QR with signed token
Frequently Asked Questions
Can I use several methods in parallel?
Yes. The TIKI SHARE platform supports RFID, smartphone, PIN and QR in parallel and selectable per user.
Which method is cheapest?
PIN and QR have the lowest rollout cost; RFID is the cheapest per opening in continuous operation.
What about biometrics?
Biometrics (fingerprint, face) are interesting for high-security areas but data-protection-heavy and rarely the first choice.
