What is EPC?
Imagine that you bought a bottle of milk in the supermarket.
The bar code that beeps when the cashier sweeps the goods can help the cashier know what you bought from the supermarket.
The electronic product code is the “upgraded version” of the bar code. All you need is a RFID reader, which can not only tell the supermarket that you have bought milk, but also tell them which farm or even which cow produced the bottle of milk!
How on earth is this achieved? Let me reveal the answer for you.
Why Do We Need EPC?
As EPC (Electronic Product Code) is increasingly used across various industries, understanding why our RFID tags need to have EPC is becoming more important. For example, in our daily lives, the logistics and supply chain processes are becoming more complex. EPC, embedded in the label, helps logistics companies track their products more effectively, thus enhancing the efficiency and security of logistics.
In large commercial supermarkets, where store managers need to manage a variety of products moving on and off the shelves, EPC data plays a crucial role. It enables them to quickly process and distinguish different types and sources of goods. With this capability, EPC significantly streamlines inventory management and product identification.
To fully appreciate how EPC benefits logistics and retail, it’s essential to delve into its definition and structure. Understanding the intricacies of EPC will provide us with a clearer picture of its practical applications in these sectors.
EPC’s Role in RFID Tags
Within a RFID tag, storage is usually divided into four main areas, each of which is used to store different types of data:
(1) Reserved Memory (reserved memory): used to store passwords and protect label access and data writing.
(2) EPC Memory (electronic product code memory): stores a unique identifier (EPC).
(3) TID Memory (label identifier memory): stores the unique serial number of the label manufacturer and product.
4) User Memory (user memory): can be used to store user-defined data.
Among them, EPC is like the ID card of every item.
Each item with an EPC has a unique number that identifies not only the type of item, but also its manufacturer and serial number.
Compared with ordinary bar codes, EPC can store more information, allowing it to identify each product with a unique serial number around the world.
EPC is usually stored on RFID tags, which are like small radio wave transmission devices.
You may have seen these labels in stores. They are usually affixed to goods and can be read by special scanning devices.
The advantage of RFID tags is that they can be read without direct contact, and multiple tags can be read at the same time, which makes inventory management more efficient.
Now that we understand the basic definition and role of EPC, let’s take a look at the specific components of EPC, which will help us understand how it is applied in practice.
Components of EPC
The structure of EPC is a bit like a segmented phone number, and each part of it has a specific meaning:
(1) Header: this section tells you what kind of EPC it is, just like the area code before making a phone call.
(2) Filter Value: it helps to quickly classify products, such as distinguishing between a single item and a whole box of goods.
(3) Partition: it determines the demarcation point between enterprise code and product code, ensuring that each company has its own unique coding space.
(4) Company Prefix: this is the company’s unique identifier, similar to the manufacturer’s code in a bar code.
(5) Item Reference: this is the code that the company uses to identify a certain type of product.
(6) Serial Number: this section is the unique number assigned to each specific product, ensuring that even if it is the same type of product, each has a different number.
In addition, EPC has many formats, each of which is suitable for different scenarios:
(1) SGTIN (Serialized Global Trade Item Number): most commonly used for retail goods, each item has its own serial number.
(2) SSCC (Serial Shipping Container Code): used to identify logistics containers to be transported.
(3) GRAI (Global Returnable Asset Identifier): identifies items that can be recycled, such as shelves or pallets.
(4) GIAI (Global Individual Asset Identifier): It used to identify company assets, such as equipment or tools.
After explaining the components of EPC, we will explore how the EPC standard ensures its global consistency and security. After all, the standardization of EPC is the basis of its global applicability.
Compliance of EPC standards
In order to make EPC available globally, EPCglobal has set strict standards for it.
These standards cover the coding structure of EPC, data exchange protocols and system integration methods to ensure that EPC content can be read normally no matter where the user is in the world.
Only by developing such standards can we ensure that the systems of different countries and companies can work together and share data seamlessly.
In addition, it is very important to protect privacy and data security. Because EPC data contains detailed product information, enterprises need to take measures to protect the data from unauthorized access. This includes the use of encryption to protect data and the establishment of strict access controls.
Therefore, enterprises need to abide by local privacy laws to protect consumers’ privacy. With the wide application of RFID tags in various industries, EPC plays a more and more important role in the fields of supply chain management, logistics and anti-counterfeiting.
Let’s take a look at a specific example of EPC in the application of RFID tags.
Application of
(1) Application in supply chain management.
Giant retailers like Wal-Mart, for example, have millions of items.
Stores can monitor shelves by affixing RFID tags to ensure adequate inventory and avoid out-of-stock.
At the same time, consumers can also scan the labels on their smartphones to read EPC content and learn more about the product.
Such as usage instructions, production dates and user reviews, and so on.
(2) Application in logistics.
Logistics companies use EPC to track every package they ship.
For example, when a package is tagged with RFID and shipped around the world, logistics companies can clearly understand the origin and contents of the package by scanning the tag and reading EPC.
This not only allows companies to better manage shipments, but also allows customers to track their packages in real time.
(3) Anti-counterfeiting and brand protection.
In high-end markets, such as luxury goods and medicine, anti-counterfeiting is very important.
The EPC in the RFID tag can help the company to confirm the authenticity of the product. It works together with TID to provide a dual guarantee for anti-counterfeiting and brand protection.
Consumers can scan the labels on the product to see what is stored in EPC, check the production and shipping records of the product, and confirm that it is genuine.
This is very effective in combating fake and shoddy products.
Summary
With the continuous improvement of science and technology, the coding technology of EPC is also making continuous progress.
In the future, EPC on RFID tags may introduce more features, such as larger data storage capacity, stronger encryption technology, and smarter tag design.
Electronic product code system will also be more and more integrated with the Internet of things and artificial intelligence technology, so that enterprises can better process and analyze data and make more informed decisions.
