RFID applied to goods management

Logistics

The main feature of RFID technology is the unique identification of items, performed both from a distance and out of the line of sight. In fact, it allows staff cost reduction, logistic flux optimization and error cost elimination.

Why using RFID in logistics management?

Most of the traditional operations involved in warehouse management are time consuming. Optical tracking technologies such as barcode and QRcode are applied to track and manage goods upload and download and shipments - even though in many less advanced warehouses operators still draw the packing list up by hand. This old-fashioned way of managing the logistics of a warehouse is the cause of many expensive mistakes and the mismatch between inventory, packing list and the enlivened goods.

Every item - pallet, box and product - in a RFID system can be identified with a RFID tag: a smart label retaining information that can be retreived using specific fixed or mobile devices and that allows to record the operations in real time. This result in a much quicker logistic flow, minimizing manual operations and eliminating the cost of manual errors.

Obviously one tracking technology does not exclude the other! RFID and optical tracking technology could coexhist and even be complementary in some applications: RFID tags could be printed with the item information and its 1D/2D code. An example of RFID tags widely used in logistics is mother / daugher: a number of printed simple labels (daughters) are associated to a RFID tag (mother); this solution is perfect for those applications in which items and their documents must be tracked.

Simplify the logistics flow: here's how

The integration of a RFID system could require many different types of devices and tags, based on the specific requirements of the costumers, the flow of the goods within the warehouse and the structure of the buildings.

One of the main RFID hardware solutions for logistics is the portal, or the gateway: a portal that detects the goods that passes through it instantanously. Portals are installed in strategic points - such as chocke points - and at the loading docks for the incoming/outgoing goods management.

Other than pallet and boxes, in logistic management systems it is possible that tagged objects are stocked outside, or that the tags need be applied onto metallic surfaces. These tough situations brought EasyRFID to study, design and develop special tags, such as outdoor IP68 semi-hard tag, the anti-crushing butterfly flag tag and anti-metal hard-tags.

Real-time inventory thanks to RFID

Integrating reading gates at loading / downloading bays or sites it is possible to update the inventory in real-time, as goods pass through the gates.

Another highly time-requiring and crucial operation is making the inventory: thanks to RFID reading devices that can reach a reading range of 16 meters (4-6 m on average), it is possible to scan the whole warehouse area, so that the list of the goods is drawn up quickly and with no mistakes. Using this type of tracking systems allows to check for discrepancies between the stock and the inventory.

Advantages compared to optical tracking technologies (barcode, QRcode,...)

Being the functioning of 1D / 2D technology very similar to that of RFID, it is often chosen as an alternative to passive tag technology.

If on one hand RFID technology involves a larger investment than barcodes, on the other it sure offers greater benefits. Unlike 1D/2D codes, tags can also be rewritten and protected with passwords, thus making it a safer and more reliable tool.

Queste due tecnologie possono comunque essere utilizzate in accoppiata; ad esempio, stampare un codice a barre, o un QRcode sul tag permette di semplificare alcuni passaggi in cui non si dispone di un lettore.

Reading skills

Optical technologies allow to read one product code at a time, making operations such as warehouse loading, unloading and inventory long and expensive. With RFID technology it is possible to read over a hundred products simultaneously.

Reading range

While optical technoloies have a reading range of tens of centimeters, the RFID reader can detect tags up to 16m away.

Reading speed

Even the reading speed of the RFID readers is astonishing; it is in fact very fast (in the order of ms for the reading of hundreds of tags).

Possibility of reading through objects

RFID tags can be scanned even if they are out of the line of sight, unlike identification systems with optical technologies.

Unique identification

The memory of RFID tags retains a unique, read-only code; every tagged item can then be tracked uniquely along its entire journey. Optical technology do not offer the same possibility; furthermore, 1D / 2D codes usually identify the family of the object and not the object itself.
