Recently, there have been numerous after another SIM card market companies targeting the application of high-capacity SIM card from to the SIM card has been integrated ZigBee, NFC and LM393 datasheet and other wireless transmission, into a SIM card-shaped , IC card, one design , wide range of new applications is a dazzling look. However, to extend SIM card-based applications are in the actual promotion had no small difficulty. Let me talk about high-capacity SIM card product. Simple application of the technology and LM393 price and market perspective, a large amount of SIM card capacity with "mass" storage space, 1GB of capacity is not difficult to achieve; from the perspective of reading and IC LM393 suppliers and writing speed, but also much faster than the external SD card reading and writing speed. Moreover, high-capacity SIM card can not...
