Its automatic frequency detection feature identifies the card type instantly, making it compatible with a wide range of access control cards and key fobs.\u003c\/p\u003e\n\u003ch4\u003eQ: How does the automatic frequency detection work?\u003c\/h4\u003e\n\u003cp\u003eA: When you bring a card or key fob close to the device and press the button, the handheld copier automatically detects whether the card operates at 125KHz or 13.56MHz. The built-in LED status indicator then lights up to confirm a successful read, copy, or write operation — providing clear, direct feedback at every step without requiring manual frequency selection.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this RFID duplicator easy to use for beginners?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The one-button design and auto-detection system make this card programmer extremely user-friendly — no software, drivers, or technical expertise required. Simply hold the source card to the reader to copy it, then hold a blank writable card to write the data. It works right out of the box for fast, hassle-free card duplication.\u003c\/p\u003e\n\u003ch4\u003eQ: What are the dimensions and build materials of this device?\u003c\/h4\u003e\n\u003cp\u003eA: The handheld RFID NFC copier measures 105 × 45 × 20 mm (4.13 × 1.77 × 0.79 inches) and is constructed from durable ABS plastic, keeping it lightweight yet sturdy enough for regular everyday use.
