RFID Journal Staff asked 15 years ago Is there an RFID tag that can be embedded in a laptop and be read 50 to 60 at a time?

It sounds like you want to track laptops leaving a production facility. TNT Express, a Netherlands-based logistics and shipping company, tagged laptop boxes with Alien Technology's ALN-8354-R "M" tags a few years ago, and received good read rates (see TNT Steps Up China-Germany RFID Trial).
The company didn't embed tags in the laptops, so it's not exactly what you want to achieve. However, ultrahigh-frequency (UHF) tags have improved over the years, so a standard passive UHF tag might work for your purpose. There is usually a lot of Styrofoam around a laptop in a box, creating separation and allowing tags to be read. The one caveat might be whether there is a place to embed the tag where there is some space between that tag and surrounding metal components.
Cognizant has deployed a system with which it reads passive tags on laptops as they leave its facilities, which is an interesting and effective application of the tag after supply chain benefits are realized (see Eating Your Own Dog Food: Cognizant Uses RFID to Track Laptops).
