The Challenge
Sodexo faced three critical limitations with existing unattended retail solutions:
Product Complexity
Traditional smart coolers rely on computer vision, which struggles with:
- Visually similar items: Spaghetti vs. Lasagna, Caesar Salad vs. Garden Salad
- Variable portion sizes: Half sandwiches vs. full sandwiches
- Fresh food recognition: Sauces, garnishes, and seasonal variations
Security Concerns
- Micro-markets: Open-shelf concepts suffered from 8-12% shrinkage (theft)
- Limited locations: Could only deploy in high-traffic areas with security guards
- Premium food waste: Fresh, high-value items most likely to be stolen
Poor Customer Experience
- Vending machines: Limited to one-item-at-a-time selection, frustrating for customers buying lunch sets
- Long checkout times: Average 45 seconds per transaction
- No bundle purchasing: Couldn't offer "meal deals" (sandwich + drink + snack)
The Solution
Sodexo partnered with IoTSong.com to deploy Scale-Based Smart Coolers across Singapore's central business district, leveraging precision weight sensors for frictionless, accurate retail.
IoTSong Scale-Based Smart Cooler Features:
Precision Weight Recognition

- ✓ Instant item identification based on exact weight signatures
- ✓ Multiple item handling: Customers can grab 3-5 items simultaneously, system identifies each
- ✓ 99.8% accuracy even with visually similar products
Advanced Security Design
- ✓Fully enclosed cooler with controlled access via app/QR/card
- ✓Weight verification: System detects if items are removed but not paid for
- ✓Camera backup: Visual confirmation for edge cases (0.2% of transactions)
- ✓Shrinkage reduced to <1% (vs. 8-12% for open micro-markets)
Superior Customer Experience
- ✓Grab-and-go convenience: Open door, take multiple items, close door — done
- ✓Average transaction time: 8 seconds (vs. 45 seconds for vending)
- ✓Bundle purchasing: Natural multi-item selection increases average ticket size
- ✓Mobile app: Pre-order, loyalty points, and personalized recommendations
Strategic Placement Flexibility

- ✓Corporate pantries: 24/7 access for shift workers and late-night teams
- ✓Co-working spaces: Flexible food service for dynamic tenant mix
- ✓No security guard required: Enclosed design enables deployment in lower-traffic areas
Sodexo-Specific Customization

- ✓Dietary filters: Vegetarian, halal, gluten-free auto-tagging based on weight + SKU
- ✓Corporate catering accounts: Direct billing to company accounts for employee meals
- ✓Fresh food optimization: FIFO (first-in-first-out) alerts to minimize food waste

Client Testimonial
"The scale-based smart cooler technology is a game-changer for our grab-and-go strategy. We can now offer our full range of fresh, chef-prepared meals in locations that were previously impossible. The ability to distinguish between visually similar items like lasagna and spaghetti with 100% accuracy eliminates customer friction, and the security enclosure means we can deploy anywhere—even in 24/7 office lobbies without staff."
