5. Definition & Typical Use Cases
   Definition

6. An electronic badge pin is a small wearable electronic device that attaches to attendee lanyards, badges, or clothing and performs one or more of: displaying name/branding (LED matrix, e-paper), proximity/attendance detection (BLE, RFID, NFC), data capture and transfer (BLE/GATT, NFC, UHF RFID), or interactive functions (sound, vibration, programmable LEDs).
7. Core components: enclosure, attachment mechanism (pin/magnetic), display or indicator, microcontroller/SoC, power source (coin cell or rechargeable battery), radio module (BLE/NFC/RFID), firmware, and optionally cloud integration.

Typical use cases
– Name/role display: temporary LED scrolling name tags for staff or attendees.
– Attendance tracking: BLE beacons or RFID pins for session check-in and movement analytics.
– Lead retrieval & contact exchange: NFC or BLE BLEtoBLE pairing for exchanging contact vCards.
