Do NFC tags run out of battery?

Most NFC tags are passive devices, meaning they do not have a built-in power source like a battery. Instead, they draw power from the electromagnetic field generated by an NFC reader when it comes into close proximity. This allows them to operate without needing a battery, making them very convenient for various applications like contactless payments, access control, and inventory management.

However, there are also active NFC tags that do have a battery. These are less common and are typically used in applications where the tag needs to perform more complex functions or communicate over longer distances.

Do you have a specific use case in mind for NFC tags?
