  "abstract": "Modern buyers enjoy the convenience of digital payments, but not all\r\npoints of sale always have an Internet connection. Trusting the buyer\u2019s\r\ndevice to honestly report that a payment was definitively made puts merchant\u2019s 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.",
  "description": "The 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.\r\nhttps://taler.net/en/",
