Trusting the buyer’s\ndevice to honestly report that a payment was definitively made puts merchant’s revenue at risk. We present an inexpensive and usable solution for merchants to verify that a buyer correctly completed a payment even when the point of sale is offline.\n\nThe talk will cover the design details and talk about the current implementation using GNU Taler: a free software, privacy focused and online payment which is built with some properties of cash.\nhttps://taler.net/en/","original_language":"eng","persons":["sebasjm"],"tags":["camp2023","57130","2023","Bits \u0026
