According to Haresh Patel, WJ's senior VP of sales and marketing, the WJM1000 was developed in partnership with a "top tier printer partner." As a result, the module "incorporates unique features and commands specially designed for printers and battery operated mobile devices, essential for wide-spread deployment of item-level tracking."
The module's "simple but powerful" command set supports custom application creation via an open-source DLL and API, according to the company. The free development software package is said to include support for WJ's API, the open source DLL, and "user friendly" demo software that provides read/write/locking capability to RFID tags. The software, which runs on "most" Windows CE or Windows Mobile devices, is available for download
