Payment Widget is a Calypso Payment functionality to generate widgets for invoice payment, which can be sent to the client or embedded on any web page.

The widget indicates the amount to be paid, the available cryptocurrencies and description of payment. When paying the amount specified in the fiat currency, the exchange rate is fixed for 15 minutes (60 minutes for BTC) from the moment the invoice is created.


Each type of visual aid has pros and cons that must be evaluated to ensure it will be beneficial to the overall presentation. Before incorporating visual aids into speeches, the speaker should understand that if used incorrectly, the visual will not be an aid, but a distraction.

An invoice is a document given to the buyer by the seller to collect payment. It includes the cost of the products purchased or services rendered to the buyer as well as lists products/services
