It is a tool to find out easily if there is suspicious transmission being emitted from a certain device and might give you a first and easy idea of the type or frequency of the radiation without the need of large and really expensive equipment. Most likely it will not give you all the information you need to specify the exact source, purpose or destination of the transmission. For a total detection you need additional tools. Credit cards work with magnetic strip and induction for NFC which can not be detected from a distance with this device. We use this tool for first sight to check if there is something suspicious. If so we get our spectrum analysers etc and check it in depth. If the skimner is passive (just reading and storing data locally without transmitting it right away) you will not be able to detect it this way. ## Frequently Bought Together - i4 Technology Anti Spy Bug Detector | Professional RF Signal Detector | High Sensitive Spy Bug Sweeper | Search for GPS Tracker, Mobile Phones, Wi-Fi, 3G, 4G, GSM BH-03 Expert | FCC, CE and ICES - JMDHKK K18+ Hidden Camera Detector, Spy Camera Finder, Bug Detector, Magnetic Field Detector, Listening Device Detector – Portable Privacy Protection Tool for Home, Office, Hotel, and Travel Security --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/231394405-anti-spy-bug-detector-professional-rf-signal-detector-high-sensitive](https://www.desertcart.pt/products/231394405-anti-spy-bug-detector-professional-rf-signal-detector-high-sensitive) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-05*
