Review on LIBO RFID Smart Card Reader Writer NFC 13.56MHz Copier 125KHz Duplicator Multi-Frequency Decoding Software USB Support with 125KHz/13.56MHz Dual Frequency Writable Key Fobs - Enhanced SEO-friendly Product Title by Adrian Love

Based on my experience, this device works great on a range of frequencies that allow me to duplicate any memory card easily. As someone who works with computers, this has been a must-have accessory for my toolkit. The best part is that it is not limited to just one frequency, so I can duplicate any memory card regardless of its frequency. However, the only downside is that it can be a bit tricky to figure out at first, but once you get the hang of it, it's smooth sailing.
