Card Entry System

Card entry access

Cards, readers, control panels
When a card is presented at a card reader — usually sited at the door — the reader extracts the card’s verification information, or credentials, and sends it to the data processor in the control panel. If the data matches the database, the control panel returns a signal to the card reader which signals the unlocking mechanism.

Henry Gates Security uses a number of highly reliable Card Entry System manufacturers for our access systems. We keep up to date with product specifications, industry advances and technology improvements.

Designing tailored systems
We make sure that what we provide our clients is state of the art for higher security levels or to integrate with an existing system, or a reliable, less complex system for lower requirement levels.

Some clients request LCD indicators (green, red) and particular functions for collecting data, for CCTV recording, audio communication or clocking in or out.

We know the advantages and disadvantages of each option, and use the right card readers for the job, for instance:
• basic for card number or PIN reading and redirecting to control panel for lock release
• semi-intelligent for locking control, still reliant on control panel for verification
• intelligent for lock control and access decisions through its own inbuilt capabilities
• IP or internet-based controllers for direct connectivity to a host PC.

We rely on market-leading manufacturers who have well-established reputations for product quality and capability.

Installation, wiring
We undertake full installation and wiring of the system, and guarantee our work.

Access control cards

Swipe cards
The integrated circuitry in these cards enables them to provide ID verification, data storage and application processing. Again, it’s not new technology, but a combination of patented concepts from 40 years ago.

The ID data is stored on a magnetic strip between the laminated cards. The technology — still used for credit and debit cards today — is being overtaken by pointless contact technology, with greater integrated security encryption.

Smart cards
These are highly capable of credentials authentication, but because of their integrated circuitry that combines data memory and storage, ID verification and micro-processing, are more feasible for high-end security and for national citizenship cards.

Proximity cards
This form of contactless card can be read from a device in a pocket or wallet up to 5cm away. Among its numerous capabilities, a passive contactless card is used as an access control door key-card.
