How to Send a Swift Wire for Developers

Cool to see how swift wire payments works in practice, but using JS floating point numbers for money amounts is a disaster waiting to happen

Hey HackerNews,<p>I published iso20022js.com a few weeks ago, and I was incredibly surprised by the overwhelming traction it received. I wanted to share more about some payments fundamentals that engineers might need in order to run this package - specifically, how sending these types of bank payments actually works.

&gt; you will need to configure the bank to allow for direct transmission. This is a process that your bank will need to complete with you.<p>How easy is this process? Are all banks required to provide such a service? How about countries outside the USA

But sending the transaction is just ONE part of the ISO. There are a lot of other different messages that are part of the standard: <a href="https:&#x2F;&#x2F;www.iso20022.org&#x2F;iso-20022-message-definitions" rel="nofollow">https:&#x2F;&#x2F;www.iso20022.org&#x2F;iso-20022-message-definitions</a>

This is cool; I&#x27;d love to hear more about how the actual transfer of money works e.g clearing, r-transactions and so on if you&#x27;re looking for a follow up blog ;)

Nice article! It&#x27;s always interesting to look behind the scenes of payment infrastructure.<p>BTW, when I tried the interactive demo [1] I noticed that it appended &quot;undefined&quot; to the end of the generated XML. Happens both in Firefox and Chrome, so it doesn&#x27;t seem to be a browser quirk.<p>[1] <a href="https:&#x2F;&#x2F;www.iso20022js.com&#x2F;demo" rel="nofollow">https:&#x2F;&#x2F;www.iso20022js.com&#x2F;demo</a>

nit: it’s been called ‘Swift’ for a while, not ‘SWIFT’.
