Introduction The NFC Booster Antenna is an ingenious way to boost NFC (13.56MHz) performance of your Flipper Zero. It's a flexible PCB sticker that has two embedded antennas: one is tuned exactly to your Flipper Zero's NFC antenna - and the other is larger antenna that modifies the RF field shape for better performance & read range, especially for emulation, implants and small fobs. It's completely passive, no batteries are required. Simply stick it to the back of your Flipper, and you're boosted! Range improvements vary on the size of the target badge: implants and small fobs can see up to 10mm extra read distance, and emulation performance is dramatically better. Business-card sized tags see smaller range improvements, as their antennas are already large and well matched with the Flipper's internal antenna. These are boosters: The increase the read range. If you're looking to also displace the reading zone to somewhere else, we recommend the Range Extender product for Flipper Zero - which has a built in booster, but also has an external antenna + cable, allowing you to move the reading field completely apart from your Flipper!
