General
These tests have been carried Texas Instruments laboratories provide information concerning performance TIRIS transponder inlays conditions approximating those found user environments, with results which applicable real-world situation. set-up described here used measure performance transponder inlays after carrying series tests described Chapter criterion used determine definition good transponder inlay performance maintenance readability without errors during testing processes.
Test Set-up
test configuration, Reader/Antenna (RI-K02-320A), connected host Interface. control Tag-it Reader Antenna Set, Tag-it Navigator software, utility demonstration program which downloaded from TIRIS site, installed.
Note: Tag-it Navigator Windows® program capable communicating with Tag-it reader standard serial interface. supports Host Protocol implemented reader, allowing execution commands such writing reading data from Tag-it transponders. Tag-it Navigator, which runs within Windows® environment, menu-driven employed assist reader set-up, tuning, diagnosis. additionally transponder responses initial experimentation testing with Tag-it system. also provides data time information display acquired data number formats.

Test Results
Test Results performance transponder facing metal background depends primarily distance between transponder inlay metal background well transponder size type. Both types metal tested gave similar results, these being shown figure X-axis this graph shows test distance between transponder metal object, while Y-axis shows percent terms relative read range, i.e. percentage reduction read range within user's environment. (This form reporting allows direct transfer results real-world environment.)

Effects Contact with various Materials
Since transponder inlay often direct contact with other materials, example mechanical support purposes, this test been carried gather data relating this condition. distances used between test materials transponder inlay differ according type material used, with some cases test material being attached directly transponder inlay.

Ultra-Violet Sensitivity Test
This test carried approximate, under laboratory conditions, effects exposure transponder inlays ultra-violet light. transponder chips were placed open ceramic housings then exposed strong ultra-violet light source, EPROM eraser (Spectroline Model T/F) being used this purpose. Similarly, transponder inlays themselves were placed open ceramic housings irradiated first from top, then turned through 180° irradiated again. Test Conditions blocks programmed with 5555555hex Check user block contents Check number Check lock function
