Battery-less active and passive hybrid device for secure wireless payment and method thereof

A method for providing contactless payment capabilities to a traditional wearable device by a battery-less active and passive hybrid device for secure wireless payment comprising a secure element adapted for storing at least one secure payment applet and at least one token for secure contactless payment and operatively connected with an active operation unit and a passive operation unit, comprising steps of:

• mounting or embedding the battery-less active and passive hybrid device at or into the traditional wearable device;
• switching or setting the battery-less active and passive hybrid device to an active state by having the active operation unit activated wirelessly on demand to enable the battery-less active and passive hybrid device to function as an active device and the secure element provisioned with a personalization information of a payment card and/or a payment token of the device;
• and
• switching or setting the battery-less active and passive hybrid device to a passive state by having the active operation unit deactivated and the passive operation unit activated/configured to enable the battery-less active and passive hybrid device to function as a passive device and the secure element configured for conducting payment token verification and/or contactless payment transaction operation;
• wherein in the active state the active operation unit is activated by operatively coupled with and powered wirelessly by a wireless power transfer unit for conducting wireless data communication with a provisioning unit, preferably a smartphone, for provisioning of the personalization information of the payment card and/or the payment token of the battery-less active and passive hybrid device to the secure element from the provisioning unit;
• and
• wherein the active operation unit comprises a first wireless communication unit adapted for coupling and conducting wireless data communication with the personalization information and payment token provisioning unit, and operatively coupled with a wireless power receiver unit and/or a transient power storage unit, preferably a supercap, adapted for receiving and/or storing power from the coupled wireless power transfer unit.
