    • Security Tools to safeguard physical assets The way the RFID tracker works for laptops Many organisations assign laptops to their workforce to enable them to keep in touch with the firm from RFID, a combination of radio-frequency-based and microchip anywhere, anytime. In such a scenario, the security of technology helps in identifying an asset. For tracking, an active RFID the laptops, which invariably carry crucial work-related tag of 1.5” (3.8 cm) to 0.765” (1.9 cm) is embedded into the laptop. information, is vital. The RFID reader has both the laptops ID as well as the employees tag ID associated with it.
