Transponder type explanation

Basics

The trovan® identification system consists of two basic elements: the reader and the passive transponder (the ID tag).

Since trovan® transponders are completely powered by the reader, they are maintenance-free and require no batteries. The reader emits a low frequency electromagnetic field via it’s antenna. When a transponder passes within its range, it is energized, causing it to transmit its ID code back to the reader.

Each trovan® read-only transponder is pre programmed at the factory with one of 550 billion unalterable World wide unique ID-numbers. This approach results in a tamper proof system to a broad variety of identification applications.

Trovan unique™ read-only system

The trovan unique read-only system is well-suite to applications that require a high level of data security. Each trovan® read-only transponder is programmed with a unique 10-digit ID code during manufacture. Comprehensive automatic test methods ensure that no code exists in duplicate in any of the trovan® unique transponder types, and that codes are programmed correctly in readable manner. Once the code is programmed at the time of the transponder’s manufacture, it can not be counterfeited or tampered with. A total of 550 billion World wide unique ID-codes is available. 

ISO compliant Animal ID

The ISO compliant read-only system consists of manufacturer-preprogrammed transponders conforming to the ISO 11784/85 standard. Our ISO compliant transponders are FDX-B type transponders, with a 15-digit ID code featuring the Trovan® / AEG manufacturers code. These transponders are designed for use in animal ID applications that do not require unique ID codes and/or data security. 

Trovan Flex™ read-write system

The trovan® flex system of reprogrammable transponders and reader-programmers is designed for use in applications in production control and logistics, where the customer requires data carriers capable of being programmed with item-specific information, where reporting and archiving requirements do not call for the maintenance of a central database.

Trovan® flex transponders feature 264 bits of memory, yielding up to 15 ASCII characters. The ability to change the ID code can be controlled by password. The programmer also has the ability to permanently lock in programmed code, either in its entirety or on a block-by-block basis.
