Skimmer Detector

Protect yourself from credit card skimmers every time you swipe.

Skimmer Detector uses your iPhone's Bluetooth to silently scan for the wireless devices that criminals secretly attach to ATMs, gas pumps, and payment terminals to steal your card data. In seconds, it can alert you to suspicious Bluetooth signals nearby — before you insert your card.

How It Works

Credit card skimmers often communicate wirelessly via Bluetooth or BLE (Bluetooth Low Energy), transmitting stolen card data to nearby criminals. Skimmer Detector scans for these signals in real time, cross-referencing discovered devices against a database of known skimmer hardware signatures — including the cheap Bluetooth modules most commonly found inside skimming devices.

Features

• Live Radar Display — A continuously sweeping radar shows all nearby Bluetooth devices at a glance, with color-coded risk indicators
• Risk Assessment — Every detected device is automatically scored Low, Suspicious, or High risk based on its name, advertised services, and hardware signature
• Distance Estimation — See how far away each device is, so you know if something suspicious is right at the terminal you're about to use
• Instant Alerts — Get notified the moment a high-risk device is detected nearby
• Detailed Device Info — Tap any signal on the radar to see full details, risk factors, and exactly what to do if a skimmer is suspected
• Privacy First — All scanning happens entirely on your device. No data is ever collected or transmitted

Where To Use It

• Gas station pumps
• ATMs and cash machines
• Parking meters and kiosks
• Anywhere you insert or swipe a payment card

Stay Protected

No app can guarantee 100% detection — skimmer technology evolves constantly. Skimmer Detector is a powerful first line of defense, but always visually inspect card readers and prefer tap-to-pay when available.
