1. What a store sends
Smart catering covers smart ordering, kitchen monitoring, ingredient traceability, and the open kitchen program. Sensors, terminals, and the communications gear collect, send, and process data so the operator can decide on facts. The IoT SIM is the link those devices depend on. How stable it is, how secure it is, and what it costs all shape how well the store runs.
SimtoLink has worked in catering for years and supplies IoT SIMs and international IoT SIMs. The 4G SIMs run on China Mobile, China Unicom, and China Telecom, and cover 2G through 5G, so the card can follow bandwidth, latency, and the site. The platform manages the card life: data use, the plan, and a fault diagnosis.
2. Ordering screens, lockers, the kitchen, and the code
A payment at the lunch rush, a locker open, and a kitchen stream do not ask the same thing of the link. The payment cannot drop. A traceability scan can retry.
Ordering screens and self-service ordering
Ordering screens stay on the menu, payment, and order systems over 4G, and the transaction success rate has to hold at the lunch rush. Monthly use is about 100–300MB, with round-the-clock uptime and low latency.
Pickup lockers and delivery lockers
Pickup lockers report pickup status, compartment occupancy, and fault alerts, and they take a remote open and a restock reminder. A 4G IoT SIM holds the link when stores are scattered.
Open kitchen and sunshine kitchen
An open kitchen uploads kitchen video live to the regulator so food-service rules and the public display are both met. 4G carries several video streams, about 200–500MB a month per store.
Ingredient traceability and the supply chain
Ingredient traceability follows food from the code through the scan. A 4G IoT SIM keeps the traceability terminal live with the tracking system so a regulatory report can go out.
3. What the store link has to do
- Store coverage: Ordering screens, pickup lockers, and open kitchens sit in many stores, and most have no reliable cable. 4G keeps them up 7×24 and holds the transaction success rate at peak.
- Payments and orders: Ordering screens must stay live with the menu, payment, and order systems. A payment flow cannot drop. Use VPDN and more than one operator.
- Open kitchen: Kitchen video has to reach the regulator live, for supervision and for the public display. Several streams use a lot of bandwidth.
- Ingredient traceability: Code-assignment and scan terminals stay live with the tracking system for end-to-end traceability and regulatory reporting.
- Platform connections: Connect the food-service and POS systems and the regulator, so multi-store management, reporting, and the API loop stay closed.
4. Which SIM fits which store device
An ordering screen and a kitchen camera do not need the same bandwidth. The table is a starting point:
| Use | Recommended network | Why it fits |
|---|---|---|
| Ordering screens, self-service ordering | 4G | Live menu and payment, about 100-300MB a month |
| Pickup lockers, delivery lockers | 4G | Pickup status, compartment occupancy, remote opening |
| Open kitchen, sunshine kitchen | 4G | Multi-stream video backhaul, about 200-500MB a month per store |
| Ingredient traceability terminals | 4G | Code assignment and scanning, tracking-system connection |
5. How much data a store device uses
In a catering deployment, one device typically uses about 100–500MB a month. The figure moves with how often it reports, how big each packet is, whether video is in the stream, and how many remote commands go out. This is a high-volume use, about 5–20MB a day per device, and it can include video, a live data stream, and a remote diagnosis.
Leave 20%–30% spare for the gap between the lunch rush and a quiet hour. A SimtoLink data pool lets many SIMs draw from one allowance, so a busy store does not starve a quiet one. The platform watches usage and alerts at a threshold you set. Compression, smarter reporting, and a local cache all bring the volume down.
6. Security and compliance
- Security level: Medium. Payments and transaction data are in scope.
- Network: VPDN private network, TLS, and an IP allowlist.
- Compliance: SimtoLink provides VPDN, a private APN, and completes real-name registration for the SIMs.
7. What SimtoLink would deploy
For ordering screens, pickup lockers, and open kitchens, use a 4G IoT SIM. An ordering screen has to stay on the menu and the payment system. A locker has to report whether a meal was collected. SimtoLink plans for 99.9% network availability, a shared data pool, and an API into the food-service or POS system.
8. Putting stores on the network
Rollout:
Size the plan to the device, and check the signal in the store. Set VPDN and the APN, plus an IP allowlist, and alert at 80% of the data allowance. SimtoLink stays with the project from the first store through the chain. Contact us for a plan built around those sites.
