A phone powers the card with a tap. No Battery. No App. Just instant connection.
Deep Research: The Mechanics of the "Magic Tap"
1. The Hardware: Passive NTAG Technology
● The Chip: Newbi cards use NXP NTAG series chips (typically NTAG213 or NTAG216). These are "Passive" tags, meaning they have no battery.
● The Antenna: Surrounding the chip is a tiny copper or aluminum induction coil.
● How it Activates: When a smartphone gets within 4cm of the card, it emits a tiny electromagnetic field. This "wakes up" the card’s antenna, powering the chip just long enough to send its data to the phone.
2. The Protocol:NFC Data Exchange Format
● The Language: NFC devices communicate using a universal "language" called NDEF.
● The Instruction: Newbi encodes its chips with a URI Record. Instead of trying to cram all your contact info onto a tiny chip (which has limited memory), the card sends a single, high-speed instruction: "Open this specific Newbi URL."
● The Result: This is why it’s so fast. The phone doesn't have to "read" your whole bio; it just opens the link to your cloud-hosted profile.
