王子制纸在世界上首次成功开发了在纸的抄造过程中抄入IC芯片而生产IC卡纸的技术.以前IC卡都是将IC芯片以粘贴的方式制造的,该企业开发的IC卡纸运用特殊的制造方法,将宽频带微片(MM即MultibandMicrochip,是频率为13.56MHZ—2.45GHZ的微片,具有尺寸为0.5mmX0.5mm世界上最小的内 For the first time in the world, Oji Paper successfully developed the technology of producing IC card paper by copying into the IC chip during the papermaking process, and IC cards were manufactured by pasting the IC chip. The IC card paper developed by this company Using a special manufacturing method, a broadband microchip (MM, Multiband Microchip, a microchip with a frequency of 13.56 MHz to 2.45 GHz with a minimum inner dimension of 0.5 mm x 0.5 mm
