Frequently Asked Questions

Do desktop readers need special software?

No. USB keyboard-emulation mode types the tag ID straight into any application — ERP, browser, or spreadsheet — with no drivers.

Can these readers write to tags as well as read?

Yes, read/write models can encode tags, keyfobs, and smart cards at the desk — useful for card issuance and tag commissioning stations.

What's the read distance of a desktop reader?

Desktop proximity readers are deliberately short-range (up to ~10 cm) so operators control exactly which card or tag is read.
