Why does AP501 not use the RFID technology?
The RFID technology allows the user to unlock a lock without physically touching the key to the sensor, and Sunnect has sold other digital door locks in the past that used the RFID technology. But for the AP501, whose first and foremost mandate was ‘real security’, we decided not to use the RFID technology for two reasons. First, a plastic cover would be required for the RFID sensor which would weaken the robustness of the lock. Second, the RFID sensor consumes far more battery power than the Tag Key technology if it is always on. If it is not always on, it would require an activation button which negates the convenience of the RFID technology. The Tag Key technology we adopted addresses both of these concerns by allowing us to mostly use metal parts for the sensor and to eliminate an activation button.
