RFID seals contain RFID tags that transmit container information when read by an RFID reader. The RFID seal combines the mechanical security of standard seals and the electronic security of electronic markers. The RFID seal tag has its own unique ID and reads/writes to its own user memory. Each container or truck is to be monitored by the RFID seal.
RFID Seal is a security tag that uses for commercial containers – bags, bins, or boxes – to prevent unauthorized access to contents while in storage or during distribution. RFID Seal Tag units integrate powerful different kind of RFID chips with high durability components, and secure, tamper-evident fasteners. Accessing a container's contents requires breaking the seal or breaching of the container to leave some way to prove to tamper.
One of the main functions of RFID security seals tag, apart from ensuring the safety of the product and processes, is to facilitate the traceability of the products they accompany. RFID e-seal tags were able to transfer the data to the RFID system automatically.
Security seals were traditionally represented by a simple string of digits or a bar code next to the identification numbers. These seals are still used, but their great drawback is that reading them is slow since it must be done one code at a time, and these must always be visible and clean, making reading and traceability a slow, manual process, less flexible, and much more likely to cause errors.
In this situation which time is increasingly critical because of logistics margins and with perishable goods, data management requires procedures that are much more agile and reduce errors to a minimum. This is why use RFID seals.
RFID seal tags able to read and write and store information in RFID chip. This RFID chip in the cable tie tags. It facilitates the extraction of data via fixed RFID readers, a handheld RFID reader. The reader collects the information and transmits it to the database where it is logged.
RFID seal tag allows mass reading, doesn't need to be in sight. In addition, it is possible to read them at a certain distance and through materials such as cardboard, plastic, or wood, commonly present in logistics environments. So RFID security seals can be read from inside packaging, boxes, or containers.
Food sector: are used mainly as strap seals for hams and shoulders, becoming a standard for quality assurance and traceability in the sector.
Retail sector: used in wholesale trade in distribution warehouses, but also in retail. This tag is also incorporated into the order processing of e-commerce or online sales sites.
Financial sector: the transport of cash and confidential documentation requires exhaustive monitoring of the merchandise, a process that has been simplified and secured by RFID applications.
The logistics sector and land transport: are used to ensure the transport and traceability of containers, cages, or other means of transport of goods.
