Access Control
Access control is among the most popular applications for smart RFID readers. Designers are familiar with many methods of administrating security:
- Physical/mechanical keys
- Magnetic strip/swipe cards
- Passwords
- Biometrics
- RFID
These designers also know the advantages, disadvantages, and costs of each. Physical keys can be lost, stolen, or copied—and they create an administrative burden. Light duty magnetic strip/swipe card are easily damaged or corrupted. Passwords can be hacked, forgotten, or leaked—and they require a keyboard or touchscreen for entry. Biometrics are common in consumer electronics but are relatively expensive to implement, and they don’t work well for industrial settings where gloves, helmets, masks, and safety glasses impede their function.
Only RFID tags and smart readers designed for industrial use can overcome these challenges. The tags are lightweight for ease of handling, and passive so they don’t require batteries. Although the tags are physical like a key, they are not easily duplicated. The tags are digitally managed, so authentication settings are quickly and simply modified even for large applications. Even if a tag is lost, it is easy to deactivate it and replace it with a new one. In addition, the tags also come with default authorization numbers which users can quickly take advantage of for simple applications without even needing to access the configuration tool.
Smart RFID readers must be robustly built for tough environments, because working environments are often wet, subject to cleaning chemicals, and may have other challenging contaminant or temperature conditions. The IDEC KW2D smart reader is designed to fit into an industry-standard 22mm cutout hole and carries an IP67 rating, meaning it is protected from dust, low-pressure water jets, and even immersion. It includes LED indicators and audible feedback to provide users with clear information, regardless of ambient noise or poor lighting.
For controlling access and tracking movement of personnel in any type of facility, the KW2D smart reader is an adaptable system designed to withstand the rigors of the factory floor.
