What Are Some of the Unique Challenges of RFID for a Restaurant Setting

Kitchen Automation

In today's fast-paced retail industry, maintaining efficient supply chain operations is crucial for meeting customer demands and maximizing profitability. Radio Frequency Identification (RFID) technology has emerged as a tool for retailers to streamline inventory management, enhance traceability, and improve operational efficiency. In this post, we will explore what RFID is, how it works, and the specific benefits and considerations of implementing within a restaurant environment.

Understanding RFID

RFID is a technology that utilizes radio waves to identify and track objects equipped with RFID tags or labels. These tags contain electronic chips and antennas that store and transmit unique identification data when triggered by an RFID reader.

How RFID Works

Each product or item is affixed with an RFID tag, containing a unique identifier. These tags can be either passive (powered by the RFID reader's electromagnetic field) or active (with their own power source). The RFID tag should be placed on the state of the product that the customer wants more information on. It can be placed on pallets in a warehouse setting, a shipper case or box, or individual units depending on the granularity of data required. 

RFID readers are then used to capture data and information from nearby RFID tags by emitting radio waves. The reader sends this data to a central system for processing. In practice, this involves passing the items equipped with tags by a large reader. Some do this by installing the reader over the entrance or exit to the kitchen. Or employees can use handheld scanners to capture data by scanning. Depending on the reader type, employees may need to get close to the tags to ensure it was captured. 

The collected data is processed and analyzed, providing real-time insights into counts, location, and movement associated with the tags.

Considerations of RFID for the Restaurant Supply Chain

Accuracy and Granularity of Inventory Data

RFID technology enables accurate inventory counts, but only at the level of the RFID tag. Meaning, if the tags are only placed only on the shipper case, the restaurant has no visibility into the number of units remaining in a case after it is opened. To capture this detailed information, brands would be required to manually count the items, or use technology equipment with computer vision, like Nomad Go’s METAshelf™

Initial Investment and On-Going Maintenance

Implementing an RFID system involves a significant initial investment in RFID tags, readers, software infrastructure, and integration with existing systems. The total cost will depend on the environment in which the inventory is stored. Keep in mind, some areas of a restaurant may be 

While tag costs have decreased over the last several years, the tags effectively raise food costs. Keep in mind, if an operator wants maximum accuracy, they will need to affix a tag to individual items.

Infrastructure Requirements

Restaurants need to set up appropriate infrastructure, including wiring, RFID readers and antennas, throughout their stores and supply chain locations. In addition, coordination with all manufacturers and suppliers will be required to install tags on products during the manufacturing process.  This may require adjustments to existing infrastructure or net-new investments in new equipment.

Food Packaging and Composition

In addition to the storage environment, the composition of the packaging materials may interfere with the signals as well. Because restaurant inventory includes items packaged in different materials, such as metals, foil, or thick plastics. These packaging materials can interfere with RFID signals, affecting tag readability and accuracy.

Choose RFID tags that are specifically designed to work with challenging materials or packaging. Some tags are specifically designed for metal or liquid environments. In addition, explore alternative tag placement options, such as attaching tags to the outer surface of packaging or using specialized adhesive materials to ensure proper tag adhesion. 

Sustainability and Recyclability

Placing RFID tags on certain products may affect the recyclability of that product. Additional work may be required to make the packaging recyclable in many municipalities or regions. Larger restaurant brands should consider the impact on their sustainability efforts. 

Environment and Tag Placement

Restaurants operate in dynamic environments with diverse items and varying conditions, such as high temperatures, moisture, and frequent movement. These factors can affect RFID tag performance and require careful consideration during implementation.

Operators may need to opt for RFID tags specifically designed for harsh environments, capable of withstanding temperature fluctuations and exposure to moisture. Keep in mind these tags may come at a higher cost. It’s also important to identify optimal tag placement on items that minimize interference and maximize readability. Test different positions to ensure consistent tag performance and minimize risk of inaccuracy. 

Data Security and Privacy

RFID technology raises concerns about data security and privacy. Retailers must implement appropriate security measures to safeguard sensitive information and address customer privacy concerns. Retailers must ensure that customer information collected through RFID tags is protected and used responsibly, complying with privacy regulations.

High-Speed Readability

Restaurant environments require efficient and fast inventory management processes to minimize disruption and maximize operational productivity. Achieving high-speed readability is crucial for RFID systems in such settings.

Strategically position RFID readers in high-traffic areas, such as receiving docks or kitchen entrances, to capture tags efficiently becomes crucial to a platforms success. Optimize the placement of antennas to ensure maximum coverage and minimize interference. This should include conducting both range and interference testing during implementation to fine-tune system performance.

Staff Training and Acceptance

Implementing any new technology requires training and acceptance from staff members. Restaurants face unique challenges in terms of staff turnover, language barriers, and adapting to new processes and technologies.

Provide comprehensive training to staff members regarding RFID technology, its benefits, and its impact on their roles and responsibilities. Offer ongoing support and reinforcement to ensure successful adoption. In addition, foster open communication channels with employees, addressing any concerns or misconceptions they may have about the technology, while encouraging feedback.

Conclusion & Alternative Solutions 

RFID technology offers significant advantages for retailers operating within the supply chain. By enhancing traceability, inventory accuracy, and improving supply chain visibility, RFID enables retailers to meet customer demands and enhance overall customer satisfaction. However, retailers must carefully consider the initial investment, infrastructure and supplier requirements, and sustainability implications associated with RFID implementation. Implementation of RFID may not be feasible for everyone.  There are alternative solutions, including Nomad Go’s METAshelf that offers similar data.
