If you’ve ever tapped a card at your office door or scanned your fingerprint at the gym, you’ve already seen how access control works. But when it comes to securing your business, the real question is: should you stick to RFID cards or switch to biometrics?

As a company that’s been in the electronic security industry since 2008 and completed over 6,000 security projects, we at Pentagon Technologies have seen it all, lost cards, cloned tags, faulty scanners, and frustrated employees. So, here’s our honest take:


🔹 RFID Cards – Convenient but Not Foolproof

RFID cards are simple, cost-effective, and quick to deploy. They’re great for workplaces with a high number of employees, where issuing a card is easier than scanning hundreds of fingerprints.
But let’s be real cards can get lost, borrowed, or even duplicated. We’ve had clients come to us after realizing their “secure” RFID system wasn’t so secure anymore.


🔹 Biometrics – A Safer Bet

Biometrics—fingerprint, face, or iris scans offer a much stronger layer of protection because your credentials are you. Nobody can lend out their fingerprint. It’s a game changer for high security offices, factories, and data centers.
However, we also know these systems can get tricky: sweaty fingers, poor lighting, or a glitchy scanner can slow down entry.


🔹 The Pentagon Approach

After working with hundreds of businesses, here’s our honest advice:
•For tight security (think banks, research labs, or premium offices), biometrics is the way to go.
•For budget-friendly, fast access (schools, co-working spaces, or warehouses), RFID still does a good job.
•For the ultimate security, we often recommend a hybrid solution—using RFID for convenience but adding biometric verification for sensitive areas.

At Pentagon Technologies, our goal isn’t just to sell you a system; it’s to design security that actually works for your people and your business. That’s why many of our clients trust us to handle everything from CCTV and fire alarms to access control systems that actually keep intruders out.


Choosing between biometrics and RFID isn’t just about tech—it’s about finding a balance between security, convenience, and cost. And that’s where we can help.
