Electronic radio frequency technology is increasing the uses of handheld devices.
Electronic ID Tag Systems of Auckland has used a $25,000 R&D grant from Technology New Zealand to develop commercial applications for prototypes it receives from smart card manufacturer Gemplus.
Electronic ID Tag director Bob Williamson says the company has taken the main operating system from a handheld reader in C++ and written the software to communicate with a computer.
The tag can then capture data that is stored on the computer and downloaded via GSM mobile, infrared or radio frequency communications.
The tags have been used to assess the quality of orchards and tracking garments in Whangarei and Dunedin.
