Do NFC rings need charging?

No. NFC data rings are completely passive — they draw power from the NFC reader (your phone or a terminal) when tapped. There is no battery to charge, ever. They will work indefinitely.

Can I use an NFC ring as an office badge?

It depends on your office system. If your office uses standard NFC or MIFARE Classic readers, you may be able to clone your badge data to a ring. Many modern access systems use encrypted protocols that cannot be cloned. Check with your building's IT department first.
