T5557卡是美国Atmel公司生产的多功能非接触式射频芯片卡，属于125KHz的低频卡，在国内有广大的应用市场，如很多酒店的门禁卡都是使用T5557卡。该芯片共有330bit(比特)的EPROM(分布为10个区块, 每个区块33bit)。0页的块0是被保留用于设置T5557操作模式的参数配置块。第0页第7块可以作用户数据块使用，也可以作为保护全部数据的密码（假如在配置块中启用密码功能的话），防止非法改写数据。 第1页的1、2块保存了出厂商信息及唯一出厂ID，只能读取不可更改。T5567、T5577是T5557的升级版。
通过修改T5557卡的参数配置块，可以将t5557卡模拟成ID卡及HID卡，所以被广泛地用于门禁卡的复制行业。
