Liquid-tight smart card reader

Some embodiments include a smart card reader system that includes a liquid impermeable card reader chamber. The card reader cavity includes a secure card reader (SCR) holder bonded to a printed circuit board (PCB) to provide a liquid barrier between the SCR holder and the PCB. The PCB includes an SCR spring contact connector. The card reader cavity may receive a smart card including an integrated circuit (IC), wherein the IC is coupled to the SCR spring contact connector. A processor coupled to the SCR spring contact connector may receive an input related to a transaction using data of the smart card and execute the transaction. In some embodiments, the roller system seals the card reader cavity when the smart card reader system is not in use. 一些实施例包括智能卡读取器系统，其包括不透液体的读卡器腔。读卡器腔包括安全读卡器SCR保持件，SCR保持件与印刷电路板PCB粘接以在SCR保持件和PCB之间提供液体屏障。PCB包括SCR弹簧接触连接器。读卡器腔可以接收包括集成电路IC的智能卡，其中IC耦接到SCR弹簧接触连接器。耦接到SCR弹簧接触连接器的处理器可以接收与使用智能卡的数据的交易相关的输入，并执行交易。在一些实施例中，当智能卡读取器系统不使用时，滚转件系统密封读卡器腔。
