Smart Labels & Readers

The physical layer

Information trapped in a database is only half useful. Casabeza's label and reader system connects that information to the physical world — so a scan of a tag on an object retrieves everything the system knows about it.

Label types

Casabeza supports four label technologies, chosen to cover a wide range of use cases:

• NFC — tap-based, short range. Ideal for appliances, equipment, frequently touched items
• QR — printed codes, scannable with any camera. Ideal for storage bins, shelving labels, containers
• RFID — passive or active, longer range. Ideal for bulk item tracking and fixed-reader setups
• Barcode — linear codes for items that already have them, or for simple printed label workflows

Each label has a unique identifier and is linked to an item in your inventory. One scan tells the full story.

Label lifecycle

Labels are managed as first-class objects. They can be attached to items, detached, and reattached. The full history of every attachment and removal is preserved — so you always know what a label was attached to, and when.

Labels can also be attached directly to numeric varieties (specific sizes, quantities, or formulations of consumables), enabling scan-to-log price and quantity tracking for pantry and supply management.

Reader hardware

Fixed readers take label tracking further. Mount a reader at a doorway, a storage shelf, or a work area, and it logs every label that comes within range — automatically, over MQTT.

Each reader supports up to four channels, each independently configurable for a different label type and action:

• Stock Ingress — a scan adds one unit to inventory count
• Stock Egress — a scan removes one unit
• Room Ingress — a scan logs an item entering a location
• Room Egress — a scan logs an item leaving
• Numeric Tracking — a scan logs a price or quantity event for a consumable

Readers can be scoped to a specific room and location, and their full read history is stored and accessible from the reader's detail page.

Why it matters

The gap between a physical object and its digital record is where information gets lost. A label closes that gap permanently. Once something is labelled, anyone in the household can scan it and immediately access its full record — without knowing where it's filed, what it's called in the system, or who entered it.
