NFC signals can be blocked or disrupted by various materials and conditions. Some common factors that can interfere with NFC communication are metal surfaces as they can reflect and absorb the electromagnetic waves. Special materials like Faraday cages or RFID-blocking sleeves can block NFC signals. These materials are designed to create a barrier that prevents electromagnetic waves from passing through. NFC is designed for short-range communication, typically within a few centimeters. Increasing the distance between the NFC reader and the tag can weaken or block the signal.
If you have a specific application or scenario in mind where NFC signal blocking is a concern, feel free to comment for more details!
