About the project, we need power for

In collaboration with one of our partners, a well-funded fintech company, we are revolutionizing the payment market with a unique B2B marketplace concept. All components are offered, hardware, and software to equip everyday objects, accessories, and watches to become payable wearables. SwatchPay is already successfully implemented! and there are more than 60 banks in the network.

The market for wearables is huge. Until now, demand has been met almost exclusively through active wearables, which require a battery that must be charged, an Internet connection, and often have many other functions that make the whole thing expensive. This technology, on the other hand, does not require a battery. Energy is transferred passively via induction from the cash register, and this works for the lifetime of the wearable. So the payment function can be integrated into any wearable, and consumers can load their credit card onto it using the app and cloud platform.
