Radio-Frequency Identification (RFID) is changing the way inventory is managed across the world. Serialized tags or chips are embedded or attached to inventory, databases are integrated between inventory locations and retail locations, and managers have real-time data on a full spectrum of inventory metrics.
Transmitters and computers are required hardware involved in the data transmission process. Transmitters, or RFID readers, are appropriately placed to only interact with chips once the inventory is moving from one location to another, sending a signal to a transmitter via radio frequency waves, then sending data to a linked computer.2
RFID technology is not just utilized for increasing accountability for inventory as it moves through the supply chain. It also provides a new set of data involving how quickly inventory moves throughout each step of the chain, specific inventory that remains stagnant (no demand), and how many employees interacted with that item along the way.3 Furthermore, customers can now benefit from RFID technology.
Blue C Sushi, established in Seattle with locations in Washington and California, is bringing RFID straight to the table. Blue C promises to bring sushi to customers with the speed, frequency, and color spectrum of the Tokyo subway. 4 Executing this style of offering to customers comes with a cost: a micromanagement of inventory (sushi) available every minute to perfectly match customer demand. In an industry of slim margins and desire to minimize food waste, Blue C sought to revolutionize the buffet restaurant industry by bringing technology to assist with inventory management to maximize profits, minimize waste, and ensure the best customer experience.
Each plate, individually prepared, is embedded with an RFID chip. The plates are placed on a revolving belt that passes by customers. When the plate is removed from the belt, a signal is sent from the plate to the RFID reader to the kitchen, alerting the chefs to prepare another similar plate to replenish the belt. Similarly, a plate that sits on the delivery belt too long is tracked by the kitchen to signal a lack of demand and potentially a plate that is no longer safe for consumption.5 This is not Blue C’s first attempt to bring technology into the restaurant. They first experimented with barcode technology. The barcode system was only effective in the food safety element of ensuring sushi had not been out on circulation for more than 90 minutes. A manager could infer demand on that data, but there was also so much information valuable to a chef. 6 Blue C waited for RFID technology to be more affordable, but still took considerable efforts to integrate it into the kitchen, when it had previously been only in warehouse settings. Chip adhesion that withstand sanitization cycles and normal wear and tear meant cross-industry coordination with 3M to ensure the product had longevity. 7
Going forward, Blue C is ahead of the curve in integrating this capital-intensive technology into its supply chain. Most businesses use this technology on a global scale, but Blue C has transformed the intent to perfect just-in-time delivery, reduce waste, and ensure consumer safety is maximized. Blue C has built an operating model on the trust that this system functions properly 100% of the time. In this case, it is less risky given the assumed skillset to revert back to individual order management. Optimistically, Blue C could encourage this technology to permeate their entire supply chain from sea-to-table. Customers may find significant value in knowing where the fish on their plate originated from. The simplest answer is to tag every fish as it is sold at market, and track it to the table. Blue C is setting the precedence in the restaurant industry for an increased complexity in data management. Will anyone else be willing to take the leap into the digital age of dining? (655 words)
