The small tag excels in space-restricted applications due to its compact size. Brick tags, on the other hand, are incredibly durable. They can withstand physical stress, resist water, chemicals, acids, and extreme temperatures, and can also be mounted on or within metal. Our range of RFID UHF transponders is designed to be embedded into metal objects. Sizes vary from the smallest available in the market to the largest, which allow for long reading distances. Designed for both indoor and outdoor environments, these RFID UHF tags for metal have an IP68 class protection. They are a perfect solution for industrial and manufacturing factories, and the best solution for interconnecting objects in the new Internet of Things (IoT) paradigm. They come with various options such as 3M adhesive for easy attachment, printing options for logos or progressive numbers or batch numbers, and engraving options for serial numbers, including on the thickness side. Finally, we can encode EPC and User Memory with customer's information, even directly from a database file.     Available customizations are the following: Design: Customized different size by the customer different project request. Printing: Monochrome printing or 4-colors in offset, starting from a graphic layout  equipped by the customer in vector format . Serial number, barcode or EPC printing. Other customizations are available on demand. Chip encoding: Encoding of EPC code of RFID UHF transponders, HF and UHF tag memory write, also from database provided by the client Temporary or permanent contents-lock through a password. EPC code and TID code association in database. UID code and progressive/barcode association. UID HF code association in EPC UHF code.
