进一步地，请参阅图3和图5，作为本实用新型提供的读卡器20的一种具体实施方式，卡座21底端的正面凸设有挡板212，从而在使用时，挡板212可以止挡卡片，以定位卡片，便于卡座21中各弹性触点22与卡片上芯片电性相连。
进一步地，请参阅图3、图5和图6，作为本实用新型提供的读卡器20的一种具体实施方式，金属罩25的顶端设有挂钩252。在金属罩25的顶端设置挂钩252，以便在使用时，可以通过弹性等部件将挂钩252钩住，进而在插卡使用时，可以对卡片起到弹性缓冲作用，更好的保护卡片；并在拔卡时，读卡器20可以复位，便于下次使用。
进一步地，请参阅图4和图6，作为本实用新型提供的读卡器20的一种具体实施方式，卡座21的反面设有安装孔213，金属罩25上对应于安装孔213的位置开设有过孔253，从而可以使用固定件穿过该过孔253与安装孔213相连，以将金属罩25与卡座21固定相连，以便金属罩25与卡座21牢固连接。具体地，安装孔213可以为螺纹孔，相应固定件可以为螺钉。
进一步地，请参阅图6和图7，作为本实用新型提供的读卡器20的一种具体实施方式，卡座21的反面凸设有挡肋214，柔性线路板24的另一端置于挡肋214中，以通过挡肋214来定位柔性线路板24，并保护柔性线路板24。
请参阅图1至图3，本实用新型实施例还公开了一种POS机100，该POS机100包括机壳11、安装于机壳11中的电路板12和如上所述的读卡器20，柔性线路板24的另一端与电路板12电性相连。该POS机100使用了上述读卡器20，成本低，可以更好的保护读卡器20。
进一步地，机壳11中安装有弹簧13，弹簧13与读卡器20上挂钩252相连，以拉住该读卡器20，进而在插卡使用时，可以对卡片起到弹性缓冲作用，更好的保护卡片。
进一步地，机壳11中于读卡器20的两侧分别设有导板（图中未示出），导板上开设有滑道，而读卡器20两侧的插销26分别插入相应的滑道中，以引导读卡器20移动。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
