A Raspberry Pi (4GB class), a UHF EPC Gen2 reader with antenna, an opto-isolated relay for the gate OPEN input, and a presence sensor (loop or photocell). Target BOM is roughly under USD 500 per gate.
Yes. All open/deny decisions run on the Pi from a signed local snapshot. When the link returns, events drain from a durable outbox over MQTT or HTTPS.
On exit, a deny rule still opens the barrier and raises an alert for the watchman. We never claim hard physical exit deny. Entry can hard-deny (stay closed) for unknown or revoked tags.
English and Spanish from day one across marketing, consoles, and announcements.
Community dues go through LatAm payment adapters (Mercado Pago, Wompi, dLocal). The platform does not hold resident funds. SaaS non-payment never disables gates.
A community admin manages units, homeowners, vehicles, tags, exit rules, billing, and announcements. Watchmen run the live gate console. Super admins provision devices and communities across the platform.
