Modern buyers enjoy the convenience of digital payments, but not all
points of sale always have an Internet connection. Trusting the buyer’s
device 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.

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.

I'm going to talk about verifying payment from buyers in places where a stable internet connection is not possible from the merchant.
In online payment, one of the end is enough to be connected but then the seller need to check that the payment is valid.
I will also introduce without too much detail the online payment solution GNU Taler.
