# NFC Tracker ## What is an NFC Tracker? **NFC tracker** is a compact, portable device that utilizes Near Field Communication (NFC) technology to help you locate and keep track of important items. Unlike Bluetooth trackers, an NFC tracker does not have a battery or emit a constant signal. Instead, it contains a passive NFC chip that is activated and read when a compatible smartphone is brought within a few centimeters of it. I personally started using one after losing my keys one too many times at the gym; it has been a simple yet revolutionary addition to my daily carry. ### How NFC Trackers Work: A Personal Perspective From my experience, the beauty of an **NFC tracker** lies in its simplicity. You attach it to an item like your wallet, luggage, or pet's collar. If the item is lost, anyone with an NFC-enabled smartphone can tap the tracker. This action typically opens a web link (URL) that you have pre-configured, which can display your contact information or a "lost and found" message to the finder, facilitating the item's return. I find this community-powered "findability" to be a brilliant and often underrated feature. ## Technical Specifications and Parameters of TIANJUN NFC Trackers For those interested in the technical details, TIANJUN provides a range of high-performance **NFC tracker** products.
