Top Performance Tag for Library and Media Management Applications



Smartrac BLOCK inlays and tags featuring NXP ICODE ILT-M IC are designed to allow close stacking or contact that confuses other inductively coupled HF and LF tags. The identification rate can be up to 800 tags in one second in a single reader’s field of view.


BLOCK tags and inlays with NXP ICode ILT-M ICs offer two key benefits. Firstly, they have excellent performance in document and item identification where close stacking occurs, which is challenging environment for other passive protocols.


Secondly, Block tags and inlays also work well in applications where very fast inventory of multiple tags in the field occurs. In these cases, Block tags offer performance approaching UHF EPC Class 1 Gen 2.
