Gallagher / Cardax卡解释：Cardax IV & Smart-Card Tiers

Gallagher和Cardax传承

总部位于新西兰的Gallagher Security通过在21世纪初收购Cardax International扩大了其门禁产品线。Cardax IV 感应式格式——一种125 kHz读取范围门禁介质——在品牌重塑之前已在澳大利亚、新西兰和东南亚的数千个商业和政府站点部署。Gallagher保留了编码结构并继续制造可读取它的硬件，因此Cardax时代的安装基础至今仍在许多设施中运行。

这种长寿性给设施经理带来了实际挑战：Cardax IV卡与标准26位Wiegand门禁介质不可互换。运行带有Cardax IV读卡器的Gallagher控制器的站点不能简单地订购通用感应式卡并对其进行编程——区域代码和专有编码必须与读卡器的配置完全匹配。理解这种区别是采购任何 Gallagher兼容感应式卡 的起点，以确保其在收到后能正常工作。

Cardax IV低频格式：区域代码、设施和卡号

以125 kHz传输的Cardax IV数据结构由三个字段组成。区域代码是一个4位值，映射到十六个字母中的一个——A到P——由Cardax在初始部署时按地理位置分配。大多数澳大拉西亚的安装使用区域代码A或B，而其他市场可能会看到C到F。设施/事件代码宽16位，范围为0到65,535。卡号字段紧随其后，也是16位，允许每个设施每个区域最多65,535个唯一卡号。与普遍使用的26位Wiegand格式（使用8位设施代码）不同，这种结构使Gallagher管理员能够对大型多站点部署进行更精细的细分。

在物理基板上，Cardax IV编码使用一次写入或可重写低频芯片进行复制——T5577、EM4305和Q5仿真芯片都是兼容的载体。芯片只存储比特流；读卡器通过Cardax IV帧对其进行解码。一个正确编码的 Gallagher兼容感应式卡 具有确认的区域代码和设施分配，将在支持该格式的每个控制器上与原始 Cardax 时代门禁介质完全相同地读取。这是 Gallagher 门禁介质系列中众所周知、操作直接的部分。

采购这些低频卡需要了解三个参数：区域代码字母、设施/事件代码和卡号范围。设施人员通常可以从其门禁软件数据库或通过控制器的诊断日志从现有卡的读卡器输出中恢复这些信息。如果站点数据库已丢失，则通过连接的控制器读取活动门禁卡并检查解码的 Wiegand 输出将显示完整的三个参数。我们的指南 Corporate 1000、FlexSecur 和自定义设施代码 更详细地介绍了恢复和确认专有格式参数的过程。

The Secured 13.56 MHz Smart-Card Generation

Contemporary Gallagher Command Centre installations issue 13.56 MHz smart credentials rather than LF proximity cards for new deployments, though most sites continue to accept LF credentials in parallel during a transition period. The HF tiers use the matching smart-card silicon — a 1K contactless smart card, an AES smart card, or a high-security AES-secured smart card — personalised with a site-specific diversification key that Gallagher's Card Technology Manager (CTM) software writes during credential issuance. The reader authenticates the chip's sector or application before granting access; a credential without the correct key structure will not authenticate.

此架构已在 Gallagher 自己的技术文献中记录，并与任何严肃的企业门禁平台处理 13.56 MHz 门禁介质的方式一致。 13.56 MHz smart cards explained guide covers the cryptographic distinctions between the smart-card tiers in detail. The practical implication for procurement is that the HF tiers cannot be pre-encoded with a facility code the way LF cards can, because the diversification key is generated by and held within the specific Gallagher CTM instance managing that site. Compatible HF credentials are therefore supplied as enrolled-blank substrates: the correct chip type, the correct physical format, ready for the site's own CTM to write its keys and credential data.

Gallagher also supports an AES smart card in Security Level 3, which provides AES-encrypted sector communication. High-security AES-secured smart-card deployments are increasingly common in high-assurance government and critical-infrastructure installations where the AES-128 cryptography and Common Criteria certification of the chip itself are a specification requirement. For sites in this tier, the Gallagher Cardax 兼容卡 we supply is built on a AES-secured 13.56 MHz smart-card platform, formatted to Gallagher's expected application structure, and delivered unkeyed for site enrolment.

兼容低频卡与兼容高频空白卡：实际差异

低频和高频层之间的采购工作流程差异很大，混淆两者会导致无法部署的订单。对于低频 Cardax IV，我们提供按订单编码的卡：您提供区域代码、设施/事件代码和所需的卡号范围，卡片到达后即可在控制器中分配。无需现场编程。这与任何门禁集成商订购标准感应库存所用的工作流程相同，并且同样适用于钥匙扣和蛤壳式门禁卡。

For the HF smart-card tiers, the workflow is different. We supply the correct chip substrate — built on the matching smart-card silicon in the physical form factor your Gallagher reader expects — but the credential data and diversification key are written by your site's Card Technology Manager software during normal issuance. From the site administrator's perspective, the compatible blank drops into the existing CTM workflow exactly as a Gallagher-branded blank would. The distinction matters for ordering: HF blanks are ordered by chip type and physical format, not by facility code. Our 兼容卡与原装卡指南 以通俗易懂的语言向采购团队解释了安全高频格式的已注册空白模型，以便他们比较成本。

《 企业专有格式 类别包括其他几个具有类似层结构的品牌—— Lenel 42-bit 兼容卡, Avigilon 兼容卡和 Software House CCOTZ 37-bit 兼容卡 都遵循类似的低频可编码或高频空白划分。如果您管理多品牌资产，则相同的供应逻辑适用于所有这些品牌。

订购兼容的 Gallagher 门禁介质

对于低频 Cardax IV 订单，所需的最少信息是：区域代码（字母 A–P）、设施/事件代码（0–65535）和卡号范围。大多数采购联系人可以从其 Gallagher Command Centre 站点数据库中正在使用的介质模板下获取此信息。如果站点运行多个区域或设施代码——这在大型多租户建筑中很常见——每个块都单独订购并在我们的生产队列中清晰标记。标准卡和蛤壳式钥匙扣外形尺寸有 PVC 信用卡尺寸 (ISO/IEC 7810 ID-1)、26 位钥匙扣和薄蛤壳变体。所有低频基板都带有 T5577 或 EM4305 芯片，能够以标准感应读取范围（通常取决于读卡器天线为 5–15 厘米）可靠地发出 Cardax IV 比特流。

For HF blanks, specify the chip tier: a 1K contactless smart card, an AES smart card (SL3), or a high-security AES-secured smart card. Match the chip type to what your Gallagher Command Centre licence and reader firmware support — this is visible in the CTM credential template configuration. Card stock arrives in Gallagher-standard CR80 format, white or pre-printed to your specification, with no credential data written. Enrolment proceeds through CTM exactly as with OEM stock. The Gallagher / Cardax 兼容卡和钥匙扣 解决方案页面列出了低频和高频层中可用的 SKU，并附有每种格式的订购说明。

低频和高频订单都可以通过定制印刷来完成——设施品牌、员工照片 ID 作品、条形码或顺序编号。低频订单还可以包含带有提供的数据文件的预编码顺序卡号。对于管理具有不同区域和设施分配的多个 Gallagher 站点的门禁集成商，支持带有每块规格表的混合编码运行的批量订单。 联系我们的技术销售团队 在承诺全面生产之前，确认您的站点参数并接收格式匹配的样品。
