    • A metal card or a hybrid metal-plastic includes an acrylic resin protective clear coat layer and/or a “hard” nano-particle top-coat layer overlying any exposed metal surface in order to insulate the metal and reduce the likelihood of an electrostatic discharge (ESD) or a short circuit condition. In a particular embodiment the “hard” nano-particle top-coat layer overlies the clear coat layer. The dual stage protective layers which include a clear-coat layer and a top-coat ensure that the problem associated with an ESD and/or a short circuit condition is minimized. In addition, the dual stage protection imparted to a card by forming a clear-coat layer and a top-coat layer ensures that any card surface treatment or card decoration is protected over time from excessive wear or scratching due to use in conjunction with a POS device and/or handling.
    • 金属卡或混合金属塑料包括丙烯酸树脂保护性透明涂层和/或覆盖任何暴露的金属表面的“硬”纳米颗粒顶涂层,以便使金属绝缘并降低静电放电的可能性 (ESD)或短路状态。 在一个具体实施方案中,“硬”纳米颗粒顶涂层覆盖透明涂层。 包括透明涂层和顶涂层的双层保护层确保与ESD和/或短路状况相关的问题最小化。 此外,通过形成透明涂层和顶涂层赋予卡的双层保护确保了随着时间的推移,任何卡片表面处理或卡片装饰被保护,因为与POS结合使用而导致的过度磨损或划伤 设备和/或处理。
