Found this project today... it's an intriguing approach, not common to see someone offering a device for free. Could not find how much they charge, and if is a custodial, trustodial or non-custodial service. I doubt is non-custodial. Does anyone know some more details?
Piggy is a smart, Bitcoin-powered device that transforms how tips and donations are collected. Each device generates dynamic QR codes for instant, seamless microtransactions via the Lightning Network. Perfect for businesses, charities, and individuals, Piggy empowers you to accept borderless, secure, and transparent contributions effortlessly. Join and make every tip count with Piggy!
Piggies are free for merchants, as it’s fully subsidized by Piggy and our distribution partners.
We collect a small transaction fee which we continuously reinvest it to further subsidize more free Piggy devices to merchants. This sustainable approach allows us to keep expanding Bitcoin tipping infrastructure while keeping it free for businesses.
Piggy automatically divides each tip equally among all the employees set in your dashboard.
