Glass tube bio-electronic labels are used for identification of pet dogs, working dogs and livestock. They are divided into read-only and read-and-write labels. The maximum storage capacity of each label is 2k bits. They are produced with materials and process technologies that meet the bio-chemical and medical requirements and fully comply with ISO11784/85. Widely used both at home and abroad, they are able to effectively control such events as “rabies”. They provide all-round management of the whole process of animal growth. The electronic label is readable as long as the card reader antenna gets close to the animal’s point of implantation.
