When working with proximity (prox) cards for access control systems, you may encounter the term “card range.” While this concept may seem technical, understanding what a card range is and why it matters can make a significant difference in how efficiently and securely your access control system operates.
In this blog, we'll explain what a card range is, why it's important, and how it impacts the security and functionality of your prox card system.
What is a Card Range?
A card range refers to the sequence of numbers assigned to a batch or set of proximity cards used in access control systems. Every prox card has a unique identification number (UID), which is programmed onto the card during the manufacturing process. This number is essential for identifying and granting access to authorized users.
When purchasing prox cards, they are often sold in ranges, meaning they are numbered sequentially. For example, if you order a batch of 100 prox cards, they might have a card range from 1001 to 1100. Each card in that range has a distinct number, and no two cards share the same UID.
Why is Card Range Important?
Understanding the concept of card range is crucial for managing access control systems efficiently and securely. Here are some key reasons why card ranges are important:
1. Avoiding Duplicates
Card ranges help ensure that no two cards in your system have the same identification number. In a large organization, duplicate card numbers can create access issues, security risks, and tracking difficulties. A defined card range allows you to avoid these problems by assigning each card a unique number.
2. Access Control Database Management
When adding new prox cards to your system, you need to assign a specific range of numbers to those cards so that your access control software can recognize and track them. This makes it easier for administrators to manage large volumes of cards, assign access levels, and monitor usage without confusion or overlap.
By maintaining an organized record of card ranges, you streamline database management, ensuring that authorized personnel are accurately identified by their unique card number.
3. Future Scalability
Planning card ranges carefully allows for future growth. For example, if you anticipate adding more employees or contractors in the future, you can leave room for additional card ranges. This way, future batches of prox cards won’t interfere with existing ranges, and you can expand your system seamlessly without having to reconfigure your entire database.
4. System Compatibility
Most access control systems have specific configurations for managing proximity cards. Ensuring that card ranges are correctly programmed and recorded guarantees that the system operates smoothly. Incompatibility issues can arise if card ranges are not clearly defined or if prox cards are randomly issued without proper documentation.
5. Security
Card ranges contribute to the overall security of your prox card system. By carefully managing and tracking which card numbers are issued and to whom, administrators can detect potential breaches, such as unauthorized access attempts using stolen or cloned cards.
If a card is lost or compromised, its UID can be easily deactivated or replaced without affecting other users. Having clear control over card ranges ensures a higher level of security by preventing unauthorized access or misuse of cards.
How to Manage Card Ranges Effectively
Now that you understand the importance of card ranges, it’s essential to know how to manage them efficiently in your access control system.
1. Keep Detailed Records
Always document the card range of each batch you receive. This includes recording the starting and ending numbers of the range, the date of purchase, and any other relevant details, such as the department or individuals to whom the cards will be assigned.
This makes it easier to track which cards are in use, which are still available, and which need to be deactivated or replaced.
2. Coordinate with Your Supplier
When ordering prox cards, make sure to communicate with your supplier about your desired card range. Reputable suppliers can ensure that the prox cards you receive are part of a continuous range that does not overlap with previous orders. Some suppliers may even offer customization options, allowing you to start your card range from a specific number to maintain consistency across multiple batches.
3. Assign Card Ranges by Department or Location
In larger organizations, it may be helpful to assign specific card ranges to different departments, teams, or locations. This allows for better tracking and management, making it easier to deactivate cards when employees leave or reassign them as needed.
For instance, employees in the marketing department may have prox cards with numbers ranging from 2001 to 2100, while those in IT might have cards numbered from 3001 to 3100. This method not only improves organization but also simplifies troubleshooting if access issues arise.
4. Use Access Control Software
Many access control systems come with software that allows administrators to manage prox cards and card ranges digitally. Use these tools to monitor card usage, assign access levels, and track card numbers. The software also helps to flag any potential issues, such as duplicate cards or unauthorized access attempts, improving the overall security of your system.
