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

Security ID Systems ·

A Gallagher card — sold under the legacy Cardax brand before Gallagher Security acquired the line — encodes a 4-bit region code (letters A through P), a 16-bit facility/event number, and a card number in a proprietary 125 kHz format known as Cardax IV. Modern Gallagher installations extend into 13.56 MHz smart-card tiers of increasing security — from a basic 1K contactless smart card up to AES-secured smart cards — that use site-diversified keys, making Gallagher one of the more technically layered credential families in enterprise Gallagher 門禁。本指南解碼每個等級並解釋如何為 LF 和 HF 兩代提供相容感應媒介。

Gallagher 和 Cardax 傳承

總部位於紐西蘭的 Gallagher Security 在 2000 年代初期通過收購 Cardax International 擴大了其門禁產品線。Cardax IV 近接格式 — 一種 125 kHz 讀取範圍感應媒介 — 在品牌重塑之前已部署在澳大利亞、紐西蘭和東南亞的數千個商業和政府站點。Gallagher 保留了編碼結構並繼續製造讀取它的硬體,因此 Cardax 時代的安裝基礎在今天許多設施中仍然活躍。

這種長壽為設施經理帶來了實際挑戰:Cardax IV 卡與標準 26 位元 Wiegand 門禁卡不可互換。運行帶有 Cardax IV 讀卡機的 Gallagher 控制器的站點不能簡單地訂購通用近接卡並對其進行程式設計 — 區域代碼和專有編碼必須與讀卡機的配置完全匹配。理解這種區別是採購任何產品的起點 Gallagher 相容的近距離感應卡 到貨後即可正常運作。

Cardax IV LF 格式:區域碼、設施碼和卡號

以 125 kHz 傳輸的 Cardax IV 資料結構包含三個欄位。區域碼是一個 4 位元值,對應到十六個字母中的一個 — A 到 P — 並由 Cardax 在初始部署時按地理位置分配。大多數澳大拉西亞的安裝使用區域碼 A 或 B,而其他市場可能看到 C 到 F。設施/事件碼為 16 位元寬,範圍從 0 到 65,535。卡號欄位緊隨其後,也是 16 位元,每個設施每個區域最多允許 65,535 個唯一的卡號。與普遍使用的 26 位元 Wiegand 格式不同,後者使用 8 位元設施碼,這種結構為 Gallagher 管理員提供了對大型多站點部署更精細的區分。

在物理基板上,Cardax IV 編碼使用一次寫入或可重寫的 LF 晶片複製 — T5577、EM4305 和 Q5 模擬晶片都是相容的載體。晶片僅儲存位元流;讀取器透過 Cardax IV 框架解碼。正確編碼的 Gallagher 相容的近距離感應卡 具有確認的區域碼和設施分配,在每個支援該格式的控制器上,讀取結果將與原始 Cardax 時代的感應媒介相同。這是 Gallagher 感應媒介系列中眾所周知、操作直接的一端。

採購這些 LF 卡需要知道三個參數:區域碼字母、設施/事件碼和卡號範圍。設施人員通常可以從其門禁軟體資料庫或透過控制器診斷日誌從現有卡的讀取器輸出中恢復這些資訊。如果站點資料庫已丟失,則將活動感應媒介與連接的控制器進行讀取並檢查解碼的 Wiegand 輸出將顯示完整的組合。我們的指南 Corporate 1000、FlexSecur 和自訂設施碼 更詳細地介紹了恢復和確認專有格式參數的過程。

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.

此架構記錄在 Gallagher 自己的技術文獻中,並與任何嚴謹的企業門禁平台處理 13.56 MHz 感應媒介的方式一致。 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 相容卡 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.

相容 LF 卡與相容 HF 空白卡:實際差異

LF 和 HF 層之間的採購工作流程存在顯著差異,將兩者混淆會導致無法部署的訂單。對於 LF Cardax IV,我們提供按訂單編碼的卡:您提供區域碼、設施/事件碼和所需的卡號範圍,卡片到貨後即可在控制器中分配。無需現場編程。這與任何門禁整合商訂購標準近距離感應庫存所使用的工作流程相同,並且同樣適用於鑰匙扣和蛤殼式感應媒介。

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 相容與原廠門禁卡指南 以簡單的術語向採購團隊解釋了安全 HF 格式的已註冊空白模型,以便比較成本。

企業專有格式 類別包括其他幾個具有類似層級結構的品牌 — Lenel 42 位元相容卡, Avigilon 相容卡以及 Software House CCOTZ 37 位元相容卡 都遵循類似的 LF 可編碼或 HF 空白劃分。如果您管理多品牌資產,相同的供應邏輯適用於所有這些資產。

訂購相容的 Gallagher 感應媒介

對於 LF Cardax IV 訂單,所需的最少資訊是:區域碼(字母 A–P)、設施/事件碼(0–65535)和卡號範圍。大多數採購聯繫人可以從其 Gallagher Command Centre 站點資料庫中使用的感應媒介模板中獲取此資訊。如果站點運行多個區域或設施碼 — 在大型多租戶建築中很常見 — 每個區塊都單獨訂購並在我們的生產隊列中清楚標記。標準卡和蛤殼式鑰匙扣外形尺寸有 PVC 信用卡尺寸(ISO/IEC 7810 ID-1)、26 位元鑰匙扣和薄蛤殼變體。所有 LF 基板都帶有 T5577 或 EM4305 晶片,能夠在標準近距離讀取範圍(通常取決於讀取器天線,為 5–15 公分)可靠地發射 Cardax IV 位元流。

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 相容卡和鑰匙扣 解決方案頁面列出了 LF 和 HF 層中可用的 SKU,並附有每種格式的訂購說明。

LF 和 HF 訂單都可以透過自訂印刷來完成 — 設施品牌、員工照片 ID 藝術品、條碼或連續編號。LF 訂單還可以包含預編碼的連續卡號和提供的資料檔案。對於管理多個具有不同區域和設施分配的 Gallagher 站點的門禁整合商,支援帶有每個區塊規格表的混合編碼運行的大宗訂單。 請聯繫我們的技術銷售團隊 在承諾全面生產之前,確認您的站點參數並接收格式匹配的樣品。

常見問題

Gallagher 卡是什麼格式?

Gallagher 125 kHz credentials use the Cardax IV format: a 4-bit region code (A–P), a 16-bit facility/event code, and a 16-bit card number, transmitted at 125 kHz. Modern Gallagher installations also use 13.56 MHz smart credentials — a 1K contactless smart card, an AES smart card, or a high-security AES-secured smart card — with site-diversified AES keys managed by Gallagher's Card Technology Manager software. The two generations co-exist in many installations during transition periods.

Cardax IV 區域代碼是什麼?

區域代碼是 Cardax IV LF 資料結構中的一個 4 位元欄位,表示為從 A 到 P 的字母(16 個可能值)。它在最初的 Cardax 部署期間按地理位置分配。大多數澳大拉西亞站點使用區域 A 或 B;其他市場使用代碼 C 到 F。區域代碼必須與讀卡機的程式預期相符 — 即使設施和卡號正確,不匹配的代碼也會被拒絕。您的 Gallagher Command Centre 站點資料庫將顯示每個門禁卡範本的區域代碼。

Can a Gallagher smart card be handled at a kiosk?

No. The 1K contactless smart-card credentials issued by Gallagher Command Centre are personalised with site-specific diversification keys using the Card Technology Manager. A generic kiosk has no access to those keys and cannot issue an authenticated credential. The AES smart-card (SL3) and high-security AES-secured smart-card credentials use AES-128 mutual authentication, making the authentication process cryptographically robust. Compatible replacements for HF-tier Gallagher credentials are supplied as enrolled-blank substrates that your own CTM system enrols with its keys — the same process Gallagher uses for its own stock.

你們是否提供用於安全 Gallagher HF 卡的相容空白卡?

Yes. We supply compatible blanks built on the matching smart-card silicon — a 1K contactless smart card, an AES smart card, or a high-security AES-secured smart card — in the physical dimensions and antenna geometry that Gallagher readers expect. The cards are delivered without credential data or site keys. Your Gallagher Card Technology Manager enrols them exactly as it would enrol OEM Gallagher-branded blanks. Contact our technical sales team with your CTM credential template type to confirm the correct chip tier.

哪些 Gallagher 控制器接受 Cardax IV LF 感應媒介?

Gallagher Command Centre controllers with legacy Cardax IV reader support — including the T20, T11, and earlier Multi-Technology reader heads — accept Cardax IV 125 kHz credentials. Many multi-technology reader heads deployed on Command Centre v8 and later simultaneously accept both Cardax IV LF and 13.56 MHz smart-card HF tiers, allowing a gradual migration. Your specific controller and reader firmware version determines which tiers are active; the site's Command Centre configuration will show the credential types enabled per door.

我需要什麼資訊才能訂購 Cardax IV LF 相容卡?

要訂購已編碼的 Cardax IV LF 相容卡,您需要三個參數:區域代碼字母 (A–P)、設施/事件代碼(一個從 0 到 65,535 的數字)以及您想要編碼的卡號範圍。所有這三個參數都儲存在您的 Gallagher Command Centre 站點資料庫中,位於活動感應媒介範本下。如果資料庫不可用,連接的控制器的診斷輸出將解碼活動卡的完整三元組。LF 鑰匙扣和蛤殼式感應媒介與標準 PVC 卡片庫存一起提供。

Gallagher 相容卡是否適用於具有不同設施代碼的多站點物業?

是。每個 Cardax IV 編碼區塊都是獨立生產的,因此具有不同區域代碼或設施分配的多站點資產會將每個區塊作為一個單獨的項目訂購,並附有其自己的規格。對於 HF 空白卡,所有站點都通過相同的 CTM 工作流程進行註冊,無論站點特定的密鑰如何,因此單一 HF 空白類型涵蓋多個 Gallagher 站點。管理大型混合資產的集成商可以提供每站點規格表,並接收每個位置的標籤化、隔離的卡批次。
