RFID technology is everywhere, and it exists in many industries. We probably know it more for its presence in healthcare, logistics management, etc. However, RFID technology in food industry can add a different style. This technology offers a wide range of benefits to food companies, retailers, and consumers. Food RFID facilitates supply chain optimization. It can also help restaurant and bar operators improve their operational strategies.

What is RFID in Food?

RFID in food refers to using radio-frequency identification (RFID) technology in the food industry. RFID technology uses radio waves to transfer data between a tag or label attached to a food product and a reader device. This allows for real-time tracking and monitoring of food products throughout the supply chain, from farm to fork.

So How does Food RFID Work?

Food RFID are attached to food items as they are packaged and used as unique identification tags. The packaged items are placed on pallets or shelves awaiting shipment. The workers carry RFID scanners through your warehouse to complete the inventory.

RFID readers automatically collect data about each food item. It does not suffer from human errors that tend to occur with manual data entry. It uploads the read data to the asset management system and stores it there simultaneously.

RFID readers on the transfer doors read the RFID tags on the food items as they are loaded onto the trucks. You can easily have accurate data on which products leave the warehouse.

Suppose you are a milk processor and have thirteen sources of milk production. Some retailers only receive milk produced by three of them. Then with an RFID inventory system, you can easily ship the specified milk to your customers.

All food items in the warehouse are tagged with RFID tags that contain specific information. It allows you to determine the correctness of the goods quickly.

Food RFID Offers Supply Chain Benefits

We can often see information about food safety on news channels. Consumers are very sensitive to the source of food. Therefore, many issues must be taken care of, such as inventory control, legality, etc. Because of these issues, Food RFID is a good fit. RFID has clear advantages in the food industry.

It is common for the food industry to reuse trays and plastic boxes. They are usually reused after being sterilized. It may not seem very clear if you use the traditional method to record these boxes. Food RFID make it easy to solve the problem. RFID readers can identify and process trays and boxes returned through the supply chain and differentiated them.

Food RFID can benefit more than just the food supply chain. It can also bring clear advantages to restaurants and bars receiving food.

Restaurants and Bars Benefit from RFID in Food

By leveraging different applications, food RFID can help restaurants and bars in various ways. It includes everything from inventory tracking to customer service. In particular, its high-value data allows operators to target it to improve business operations. It can also help operators increase productivity and reduce operational costs. It also has more obvious benefits in the following areas.

Inventory Tracking

Inventory tracking is critical for every industry, especially restaurants and bars. Using RFID technology ensures that inventory is always fully stocked. Ingredients, drinks, and consumables will not run out. RFID tags attached to items also ensure that food is always within its shelf life and being used. After all, food can’t be stored or used for long periods. Once the shelf life has expired, people can waste new food. If consumers eat it, there are more likely to be serious consequences.

RFID tags and scanners keep inventory records up to date. People can tag Individual items, crates, or other containers with an adhesive RFID tag. It can store data, including the date people purchase the food, the best before date, and the use-by date.

Scanners placed on store shelves or at pantry doors and refrigerators can track every item in and out. It gives managers a complete view of the warehouse inventory. Managers will be able to know what items need to be reordered in the warehouse. They will also know the usage of perishable products, etc.

With this constant tracking, the warehouse can maintain adequate inventory levels. People can also use Perishable items up promptly.

RFID can also automate the entire process in the warehouse. The scanner automatically checks the inventory without you having to handle it yourself. It saves you a lot of time to do other things. The scanned information is also uploaded to the company’s asset management system. Managers can easily get the inventory information they want.

Speed of Service

Speed of service is a very important thing for restaurants and bars. Customers usually expect their food orders to be delivered quickly and accurately. Timely service also means getting more visitors.

Large restaurants usually receive the most complaints. Because they have multiple tables, rooms, and outdoor spaces, the waiter can easily get confused. Often, waitpersons need to call ahead before delivering a meal, resulting in extreme inefficiency. Delayed meals can also result in food being delivered at the wrong temperature and cause customer complaints.

Efficient service not only makes for happier customers but also for greater profitability. RFID can help restaurants improve their efficiency, which is why most are now using it. Managers can attach RFID tags to tables and service counters. Each employee is equipped with a handheld RFID scanner. When a customer comes to the service counter to order, the employee provides the customer with a smart order number card with an Food RFID tag. The staff can find the order faster with the card. Restaurants can analyze employee productivity through RFID tags at tables and service counters. The main analysis is the time it takes for the customer to receive the order and the time it takes to wait for the staff to deliver the food.

Food Ordering
