Although you can wear your Aeklys by Starck on any finger, be aware that the contactless antenna is in the black part and that it has been designed for be worn daily on your index finger.
The Wave Control ® system is a patented security that prevents the ring from being copied. The ring will only emit when the Wave Control ® is kept activated. This allows you to control when Aeklys by Starck can interact with its surroundings. So the Wave Control ® security can be easily activated with your thumb.
