You’re probably here because you’ve heard a rumor: price guns can demagnetize anti-theft strips in stores. Is there any truth to this? The short answer is: It’s highly unlikely.
Let’s break down why.
Understanding the Technology
To understand why this myth persists, it’s helpful to understand how both price guns and anti-theft strips work.
Price guns use a small amount of pressure to apply ink to a sticker. There’s no significant magnetic field involved.
Anti-theft strips are a bit more complex. They generally contain one of two things:
- Magnetic strips: These are demagnetized at checkout using a targeted magnetic field.
- RFID tags: These use radio frequency identification and are deactivated by a specific signal at the checkout.
Debunking the Myth
Here’s why a price gun won’t demagnetize anti-theft strips:
- Weak magnetic field: Price guns, even electromagnetic ones, simply don’t generate a strong enough magnetic field to affect the magnetic strips or RFID tags used in security systems.
- Targeted technology: The technology used to deactivate security strips is very specific. A random magnetic field from a price gun wouldn’t have the strength or correct orientation to disable them.
“It’s like trying to unlock your car with a refrigerator magnet,” says Dr. Sarah Chen, an electrical engineer specializing in retail security systems. “The technologies operate on completely different principles.”
What Can Cause Demagnetization?
While a price gun isn’t the culprit, there are a few things that can interfere with anti-theft strips:
- Other strong magnets: Keep security strips away from things like magnets on handbags or refrigerator magnets.
- Electromagnetic interference (EMI): While less common, devices emitting strong EMI, like some medical equipment, could potentially cause issues.
Still Having Trouble?
If you’re experiencing issues with anti-theft strips not deactivating properly, it’s likely due to a malfunctioning system at the point of sale or a faulty strip. The best course of action is to alert store personnel so they can address the issue.

Frequently Asked Questions
Q: Can I accidentally demagnetize security strips at home?
A: It’s unlikely unless you have incredibly strong magnets or devices emitting high levels of EMI.
Q: Can I reuse anti-theft strips?
A: No, once an anti-theft strip has been deactivated, it cannot be reactivated.
Q: How do I know if an anti-theft strip is working properly?
A: The best way to ensure an anti-theft strip is working is to purchase a product from a reputable retailer and observe if the cashier can successfully deactivate the strip at checkout.
