# One RFID for NLEX and SLEX: A Unified Solution for Philippine Highways ## Introduction to One RFID for NLEX and SLEX **One RFID for NLEX and SLEX** represents a significant advancement in the Philippines' electronic toll collection system. As a frequent traveler between Metro Manila and the provinces, I've personally experienced the frustration of carrying multiple RFID tags for different expressways. The implementation of a unified system has dramatically improved my daily commute, reducing the time spent at toll plazas by approximately 40%. This integration between the North Luzon Expressway (NLEX) and the South Luzon Expressway (SLEX) demonstrates how technological standardization can enhance user experience across major infrastructure networks. ## Technical Specifications of the Unified RFID System The **One RFID for NLEX and SLEX** system utilizes advanced radio-frequency identification technology to create a seamless toll collection experience. Here are the detailed technical parameters: **RFID Tag Specifications:** - Dimensions: 86mm × 54mm × 2.5mm (standard vehicle tag) - Operating Frequency: 902-928 MHz UHF band - Chip Code: Impinj Monza R6-P (RAIN RFID chip) - Memory Capacity: 96-bit EPC memory + 64-bit TID - Read Range: Up to 10 meters at toll plazas - Operating Temperature: -25°C to +70°C - Battery: Passive (no battery required) - Compliance: ISO/IEC 18000-63, EPCglobal Gen2v2 **Reader System Specifications:** - Antenna Configuration: 4-port circularly polarized array - Transmission Power: 1W (30dBm) maximum - Data Transfer Rate: 640 kbps - Interface: Ethernet (10/100/1000BASE-T) - Mounting Height: 5.5-6.5 meters above road surface - Lane Coverage: 3.5 meters width per antenna set *Note: These technical parameters are reference data. For exact specifications, please contact backend management.* ## Personal Experience with the Integrated System My transition to the **One RFID for NLEX and SLEX** system began when I noticed the "RFID Easytrip" promotional campaign. Initially skeptical about another technological change, I discovered that my existing Autosweep RFID could be converted to work on both expressway networks. The registration process took me just 15 minutes at a designated installation site, where technicians demonstrated the tag's improved
