Types of RFID Technology According to Frequency and Activity

Most Radio Frequency Identification technology works roughly the same way, using a reader, antennas, and a receiver to transmit signals over distances and effectively communicate relevant information.

However, some types of RFID might be especially useful in warehouse management:

• Low-frequency RFID technology: These devices use lower frequencies, generally around 125 kHz. This makes them efficient for locating any item in close proximity. For open spaces, managers might want a farther-reaching device.
• High-frequency RFID technology: Devices at 3 to 30 MHZ transfer more information faster and locate items at a longer distance.
• Ultra-high-frequency RFID technology: At 300 to 960 MZ, ultra-frequency RFID technology easily allows users to receive large amounts of data up to 25 feet away.

Microwave RFID technology: Systems like these operate at 2.5GHZ and can transmit enormous amounts of data from tags up to thirty feet away.

While frequency levels can categorize RFID technology, it can also be categorized into two distinct groups:

• Passive RFID Technology: In active RFID, batteries will power tags. This makes them especially effective at longer distances.
• Active RFID Technology: Instead of batteries, the reader uses electromagnetic fields to transmit signals and information to the receiver. While it’s less powerful than active variants, they’re cheaper.

Just knowing the types of RFID technologies isn’t enough to make the right choice for warehouse management. Individual products can differ widely, and users must consider their specific environment. That’s why it’s best to contact Energy Electronics. You’ll receive an in-depth understanding of the technology you need for all warehouse management systems.

RFID Readers vs Barcode Scanners

When it comes to warehouse management, both RFID readers and barcode scanners are popular tools for tracking inventory, but they operate differently and offer unique advantages. Think carefully before you decide which option to move forward with.

RFID Readers:

• No Line-of-Sight Needed: Unlike barcode scanners, RFID readers don’t require direct visibility of the tags, allowing for faster and more efficient scanning.
• Multiple Tag Reads: RFID readers can scan multiple tags simultaneously, making them ideal for bulk inventory tasks, such as checking an entire pallet at once.
• Longer Range: RFID tags can be read from greater distances, sometimes up to several meters, depending on the system, providing more flexibility in warehouse layouts.
• Higher Cost: While RFID technology offers advanced capabilities, it comes with a higher initial cost for tags, readers, and software.

Barcode Scanners:

• Lower Cost: Barcode systems are more affordable, with lower upfront costs for equipment and tags, making them accessible to smaller operations.
• Proven Technology: Barcodes have been used for decades and are reliable in various industries. The technology is simple and widely understood.
• Manual Scanning: Barcodes require individual scanning, often slowing down the process when handling large quantities of items.
• Shorter Range: Barcode scanners need to be close to the label, requiring more time and effort for scanning compared to RFID.

While RFID readers offer superior speed and automation, barcode scanners remain a cost-effective option for warehouses with lower budgets or less complex tracking needs. Choosing between the two depends on the specific demands of your operation.

A Shipment Example of Using RFID Technology for Warehouse Management

When considering RFID, it helps to have a concrete example of implementation and the processes associated with this technology. For this article, we’re using a received warehouse shipment as an example.

Here’s what the process might look like:

1. Attaching the RFID Tag: When a product shipment arrives, warehouse managers attach an RFID tag to each product, container, or pallet. This tag can either be an adhesive label or a hard tracker. In some cases, it might even be embedded in the product. Once the tags are attached, workers can identify them using the receiver.
2. Storing the Products: Next, workers will store products in their respective areas. They then scan the RFID tag in the storage location. Doing so will automatically update the storage database, allowing management to review the location of every item.
3. Completing inventory checks on shipped items: After a certain period, workers will need to check the inventory of the items. The reader sends out radio waves that will activate the tags and products. Workers can then quickly and easily track the necessary items. Since the database has been updated, they can also review any discrepancies between the stored items and the number of products.
4. Tracking outgoing shipments: Workers will receive a list of products and identification numbers that need to be shipped. As the shipments are packed, workers can scan the items, updating the inventory list in real-time. This makes it easier to maintain the list and minimize the risks associated with outgoing shipments. If a product is returned, the items can be scanned again so that the inventory lists accurately reflect product returns.
