NFC tags are passive devices – that is to say that they don’t have any batteries, or source of power built-in. They work on the concept of electromagnetic induction – a process by in which if there are two coils in close proximity, and one of them has a electric current flowing through it, the other coil gets an induced current, as well. No Battery Required: The incredible thing about NFC tags is that they don’t need a battery. Their power comes from the electromagnetic field your phone generates when close. It’s a low-energy, wireless way to transfer data. NFC tags don’t contain a battery; they draw the minuscule amount of power they need from the reader (e.g., your smartphone) via magnetic induction. They’re typically about the diameter of a quarter and can be fully encased in waterproof . Passive tags don’t have an internal power source and are powered by the reading device. Active tags, on the other hand, include an internal power source, such as a battery, allowing them to send.
what is an nfc tag
NFC tags do not require battery power and rely entirely on the electromagnetic field emitted by the NFC reader, allowing them to remain functional for a long time and at a low cost. NFC tags are widely used in a variety of scenarios, including product tracking, access control management, mobile payments, and smart advertising. NFC tags don’t need batteries to run: they draw their power from NFC-enabled devices that you tap or keep close to them using induction. NFC tags (image source: Amazon) However, more complex devices, like the Samsung Galaxy SmartTag2 used for tracking things, don’t have only NFC tags inside but also Bluetooth chips and batteries to power them. Actually, NFC tags don't have batteries. They get their power from just being near a powered NFC device, for example a mobile phone.
