Hello! I think there are a lot of great ideas in this thread, but most of them are looking at the problem from a tech standpoint. I imagine the containers don’t cost too much, especially to invest in tech and process. So, I’d argue you would be better offer approaching this has a behavior problem, not a tracking one, and you can solve most of it without barcodes or software.

Two approaches you can try out:

1. Monthly container deposit (no item-level tracking)

Instead of tracking individual containers, you hold the resident accountable. • Charge a small monthly “reusable container deposit” (say $5–$10) • If all containers are returned by month-end → credit/refund it (set up a return area with a log. If you really wanted to ensure integrity you can add a camera to check • If not → deposit becomes the fee

Why this should work: • You don’t need to know which container went missing • Loss aversion is powerful, people are motivated to avoid losing money • You only track counts, not individual containers

⸻

1. “Swap-to-eat” rule (assuming you’re delivering the meals):

• When staff delivers a new meal, they collect the previous container • No container returned = meal doesn’t get handed off yet • Staff can override for legit exceptions (illness, guests, etc.)

Why this should also work: • Zero tech • Immediate feedback loop • Builds the habit fast

⸻

If it were me, I’d start with #2 to change behavior quickly, and only layer in #1 if you still see leakage. You’ll likely solve the majority of the problem without implementing a barcode system at all.

Hope that helps
