I used to work for medium/big tech companies (8,000 - 70,000 employees.)

I always had a sticker on my laptop - everybody had the same laptop (or maybe one of two models.) It was a reliable way to quickly identify mine in a big group at a meeting or conference.

Funnily enough, not having stickers for me was an equally (if not more) reliable way to identify my laptop at those types of companies.
