非接触式IC卡又称射频卡，是世界上最近几年发展起来的一项新技术，在卡片靠近读写器表面时既可完成卡中数据的读写操作，它成功地将射频识别技术和IC卡技术结合起来，解决了无源(卡中无电源)和免接触这一难题，是电子器件领域的一大突破. 射频卡应用于：高速公路收费卡、公交卡、校园卡、互联网卡、物业管理卡、预付消费卡等。Contactless IC card is also called radio frequency card, it is a new technology developed in recent years, combined radio frequency identification technology and IC card technology, solved the problem of no power and contactless, it is an important improvement in electronic device area.Kaisere 's contactless card has adopted the most advanced American AIT process. The core of AIT technology is inlay embedding and module welding. The inlay is embedded into the PVC sheet accurately by ultrasonic measurement and then the module and the inlay are welded within nitrogen gas surrounding. The strength of the welding points is secured higher than 80g within the safe factor. The above techniques are the most important parts in contactless card manufacturing. In order to further enhance the card packing process and efficiency, Kaisere has set up a close cooperation with Sino Golden-Card Company as to the research and development of the application of relevant equipment. The annual capacity for contactless card is 25 million pcs.Technical specification：Chip: Philips Mifare S50 /Mifare S70, Fudan FM11RF08Storage capacity: Mifare S50: 8Kbit, 16 zones, two passwords each zoneMifare S70: 32K bit, 40 zonesOperating frequency: 13.56MHZCommunication speed: 106KboudRead-write distance:
