RFID security seals; Whilst providing some degree of security to products and processes, the main function of security seals is to facilitate traceability, thus they are marked in a variety of ways, using either QR-codes, barcodes, or serial numbers. Such markings can be easily checked to see if any foul play has occurred.
How does RFID technology work in security seals?
RFID (Radio Frequency Identification) technology, which is now used in many sectors, allows for the automatic transmission of product-related data.
Traditionally, simple numbering systems or barcodes next to an ID number have been used to make security seals traceable. These systems while still in use, have distinct disadvantages
- Only one code can be generated at a time
- Branding must always be clean and visible
- They are slow to read and trace
- They are manual processes
As these systems are manual processes, they more susceptible to error.
The security seals industry requires procedures that provide both faster data management and minimize errors. For this very reason, RFID technology is utilized in the production of security seals.
RFID tagging is a form of remote information storage. This chip can be incorporated into the body of security seals. It facilitates data extraction via fixed readers or mobile readers. The reader collects the information and transmits it to the database.
RFID technology allows for the batch reading of seals. In addition, RFID seals can be read inside the card, plastic, or wooden materials used in the logistics industry, thus enabling remote reading of multiple RFID Security Seals without the need to open packaging, boxes, or containers.
RFID Security Seals Usage
RFID Security Seals with are widely used in the following sectors
- Within the Food Sector for quality assurance and accountability
- The Retail Sector, in retail and distribution warehouses and in wholesale trade
- The Financial Sector for the transportation of cash and confidential documents
- The Logistics and Land Transport Sectors to ensure the traceability of the containers, cages, or other means of transporting goods
They are also used to provide added security to operations of
- Government Facilities
- Shopping Malls
- Supermarkets
RFID Security Seals are usually marked with a barcode or a digital marking system as an alternative measure in case of problems with RFID reading. These codes are laser etched to provide further security as they cannot be erased or manipulated. Additional security is provided by matching the chip and the branding on the seal.
Advantages of RFID Security Seals
- They can be read quickly and accurately with either fixed or portable readers
- RFID technology enables automatic identification of the container
- Further information can be easily added RFID chips can be easily added with a RFID read/write device
- RFID chips can be password protected, thus providing further security by preventing interference with the chip
- RFID Security Seals used on trucks and containers can be automatically detected when passing through RFID equipped exit doors, making entry and exit processes faster and more reliable
