Introduction: Why Emulate RFID Tags with Android Phones? In IoT development, access control testing, and smart hardware prototyping, using physical RFID cards often involves cost, logistics, and management overhead. Android phones with built-in NFC modules can emulate standard RFID cards—such as MIFARE Classic, NTAG, or ISO 14443 types—by leveraging Host-based Card Emulation (HCE), enabling rapid prototyping and system testing without requiring physical cards. HCE Simulation Principle: How Can a Phone Act Like an RFID Tag? Host-based Card Emulation (HCE), introduced in Android 4.4, enables smartphones to emulate smartcards and communicate with RFID readers via the APDU protocol: The phone generates a 13.56 MHz RF signal; Registers AID (Application ID) to handle reader requests; Developers write logic to handle incoming APDU commands and return data. This means software-based simulation can replace physical RFID cards entirely. Required Hardware and Software To successfully emulate RFID...

  Managing medical supplies in hospitals? Yeah, it’s a bit of a mess sometimes. You’ve got so many things to track, and traditional methods—like checking stock manually or writing everything down—well, they just don’t work that well anymore. Stuff gets lost, orders don’t get tracked, and suddenly you’re out of the critical supplies you need. That’s where the   Cykeo  CK-GY2B Medical RFID Storage Cabinet   comes in. It’s not just another cabinet. It’s basically a game-changer for how hospitals handle their supplies. So, What’s the Big Deal with the CK-GY2B? The  CK-GY2B  uses RFID tech to do all the heavy lifting when it comes to managing supplies. What does that mean for you? Well, every time something’s added or taken out, it gets logged automatically. No more guessing if something’s in stock or if it’s been signed out. Everything is tracked in real-time, and you always know where things are. Pretty cool, right? Here’s what really makes it shine: Real-Time...
