8 Decisions Before You Buy
Work through each step in order. By Step 8 you will have a clear specification to share with our team.
What Are You Tracking?
Weight sensor systems track quantity by weight change — they do not identify individual items. RFID systems identify specific tagged items.
- Consumables & small parts — Fasteners, reagents, PPE, production supplies. Weight sensor tracking is typically the most practical approach.
- Reusable tools & instruments — RFID item-level tracking is appropriate where tagging is practical. See the RFID Inventory Buying Guide.
- Medical & laboratory consumables — Weight sensor cabinets with access control are well-suited.
- Mixed inventory — Hybrid RFID + weight sensor configurations may be appropriate.
How Weight Sensor Tracking Works
Weight sensor inventory systems operate on a fundamentally different principle from RFID.
Weight Sensor
- Measures stock quantity by detecting weight change on each shelf or bin zone
- No RFID tag required on individual items
- Calculates remaining quantity based on known unit weight
- Triggers low-stock alerts automatically
- Does not identify which specific item was removed
RFID (for comparison)
- Identifies individual tagged items by unique RFID tag ID
- Quantity derived from tag count — not from weight
- Requires an RFID tag on every item to be tracked
- Records which specific item was present, removed or returned
Hybrid (RFID + Weight)
- Combines RFID bin identification with weight sensor quantity tracking
- RFID identifies which bin was accessed; weight confirms quantity remaining
- Available in the RIFE RFID Smart Shelf System with Weight Sensor
Enclosed Cabinet vs Open Rack
- Enclosed cabinet with access control — Controlled access via RFID badge or PIN. Best for healthcare, pharmacy and high-value consumables.
- Open-rack shelf system — No access restriction. Best for high-throughput manufacturing and MRO environments.
- Enclosed RFID shelf cabinet — For environments where item-level identity is required alongside enclosed storage.
Technology Pros & Cons
✓ Advantages
- No individual item tagging required
- Works for small and lightweight items
- Continuous real-time tracking
- Automatic reorder alerts
- ERP & procurement integration via API on supported configurations
- Supports VMI models where configured with your supplier
- Low maintenance
✗ Limitations to Consider
- Tracks quantity, not individual item identity
- Items must have consistent unit weight
- Open-access systems have no dispensing control
- Initial calibration required per bin zone
- Not suited to high-value individual asset tracking

Access Control & User Accountability
- Open-rack systems (Model 2) — No access restriction. Consumption tracked by weight change but no user identity recorded.
- Enclosed cabinets with RFID badge / PIN (Models 1 & 3) — Records which user opened the door and when.
- Smart Lockers — For controlled individual compartment access. See the Smart Locker Buying Guide →
Software, Dashboard & Integration
- Real-time inventory dashboard — Stock levels across connected cabinets and shelves.
- Low-stock alerts & reorder triggers — Configurable thresholds on compatible configurations.
- Consumption history and transaction records — Where supported by the configuration.
- Expiry tracking — Available on Models 1 and 3 where configured.
- ERP & procurement integration — API-based on supported configurations. Contact RIFE to confirm compatibility.

View Product →Frequently Asked Questions
Common Procurement Questions
Do items need to be individually tagged for weight sensor tracking?
No. Weight sensor shelves detect inventory changes by measuring weight — no RFID tags or barcodes are required on individual items. The RFID Smart Shelf Cabinet (Model 3) does require individual item RFID tags.
How accurate are the weight sensors?
The RIFE IoT Smart Cabinet and RFID Smart Shelf System use high-precision load cells. Sensor precision varies by configuration — contact RIFE to confirm the appropriate specification for your application.
Can the system integrate with our ERP or procurement platform?
API-based integration is available on supported configurations. Integration scope and supported platforms vary by product — contact RIFE to confirm compatibility before procurement.
Can we use weight sensors and RFID together?
Yes. The RIFE RFID Smart Shelf System with Weight Sensor combines both technologies — RFID identifies the bin, weight sensing confirms quantity remaining.
What happens if items have different weights?
Weight sensor quantity calculation relies on a known, consistent unit weight per bin zone. Variable-weight items require additional configuration — contact RIFE to discuss your specific inventory types.
Are the systems configurable?
RIFE systems can be configured with options such as bin sizes, shelf tier count, access control method, connectivity, alert thresholds and integration scope. Contact RIFE to discuss your application.
What is the typical implementation timeline?
Installation and configuration timelines depend on system scope, integrations and site readiness. Contact RIFE for a project-specific timeline.
