Abstract: We found that the 2KP/3KP electronic payment protocols as well as the 1KP electronic payment protocol do not possess a probably important property. The property is that if an acquirer authorizes a payment, then both the buyer and seller concerned always agree on it, which is called agreement property in this article. We also propose a modification to have 2KP/3KP possess the property.
