How do you migrate a 125 kHz site to high security without replacing every credential on day one?
That's what stalls most retrofits: the client won't approve a full card swap, and the project sits in the quote pile.
AKPROX handles the transition. Dual-frequency KPROX readers: they read what's already installed and what's new.
▪️ 13.56 MHz + 125 kHz in the same reader: legacy credentials and DESFire EV2 coexist while you migrate.
▪️ Complete kit: A22K controller, 2 KPROX readers, 5 MDTAG credentials and 5 Mobile-PASSes per site.
▪️ The A22K converts to an elevator controller or a Schlage/Aperio door handle controller as the project grows.
ATRIUM software with free updates, up to 10,000 users and a 5-year warranty.
