What works in practice
- 2.5 cm is the practical minimum on a badge.
- Print your name in text too — cameras fail in dim conference halls.
- A vCard code saves contacts offline, which matters when venue Wi-Fi collapses.
Common question
vCard or LinkedIn on a badge?
LinkedIn if you want the ongoing connection; vCard if you want your number saved even with no signal.
