Why on earth are we talking about payments on the moon?

• Space strips payments of all their comforts - no guaranteed signal, no clear rules, no easy hardware swaps, no obvious currency.
• On the Moon, the “terminal” is you: suit, device, biometrics - authentication does the heavy lifting.
• A moon‑native currency makes more sense than projecting Earth currencies, with store‑and‑forward as the default.
• Early space economies will be B2B first: oxygen, mining, logistics, infrastructure - not shopping.
• Designing payments for the Moon is really about Earth: once you see what has to work there, second-best becomes harder to accept here.

...which begs the question, how close are we to calling somewhere other than earth home?

Well, if you asked SpaceX or Blue Origin, they’d probably tell you it’s closer than we think.

Both are investing heavily in the infrastructure needed to visit the moon and stay there - to build, to work and eventually, to live in their (not-so) futuristic vision for a “self-growing city”.

Of course, there’s a big 3D picture here with many moving parts to consider, but let’s hone in on the payments side, and more specifically the universal pattern that wherever humans settle, trade follows. And where trade appears, so do payments.

So, what would it take to accept a payment on the Moon, and why, when, and how would that even work?

It sounds improbable, but extreme environments have a way of revealing what we take for granted.

In other words, you could say we’ve been looking at the crescent, now let’s look at the whole of the Moon...

Why are we even talking about this?

It’s a fair question, as it’s not like lunar retail is imminent; most businesses aren’t planning to deploy payment terminals into orbit. So why explore this at all?

Well, at the risk of simply replying “well why not?” There is actually a perfectly practical reason to explore this topic, as extreme environments force us to look at things clearly, and in the wonderful world of payments, a bit of clarity is always a good thing.

Let’s look at it this way.

When you design payments for Earth, you inherit decades of infrastructure.

• National currencies
• Regulatory frameworks
• Card networks
• Settlement systems
• Hardware ecosystems

Much of it works well, (and for good reason).

But space removes that inheritance, as in:

• You can’t assume instant connectivity.
• You can’t assume clear jurisdiction.
• You can’t assume physical terminals can be repaired or replaced.
• And you cannot assume a national currency makes sense.

When those assumptions fall away, what remains is the foundation.

To examine that foundation properly, we brought together two of Aevi’s payments experts, Adam Myers, Client Service Owner, and Martin Herlinghaus, Director of Corporate Development, for an open discussion on what payments might look like beyond Earth. Drawing on their experience across infrastructure and merchant environments, the conversation deliberately worked from first principles...

...If we had to design payments without relying on Earth’s inherited systems, what would survive

Let’s take the thought a little further and imagine what that might look like in a few realistic lunar scenarios...

Let’s imagine a worker finishing a shift inside a lunar base. He heads to a shared galley, picks a meal, and goes to pay.

On Earth, he taps a card or a phone, and the transaction clears in seconds. On the Moon, that model breaks. Networks are unreliable, and hardware is hard to replace. Physical cards make almost no sense

In this context, the device itself becomes central. His spacesuit, wrist device or embedded tech is the actual payment interface.

“Your spacesuit could effectively become your payment terminal”, Martin said.

Biometrics and contextual signals confirm who he is and that he’s actually there. The hard part is proving identity in an environment where systems must stand alone.

"Humans are creatures of habit. Transactions on the Moon would not be that different from Earth", Martin pointed out.

We already see this direction of travel on Earth with mobile wallets, wearables and tap‑to‑pay ecosystems. The Moon would accelerate it.

So if the "what" of paying becomes less interesting than the "who", what happens when the transaction is no longer about a meal, but about something a bit bigger?

Now raise the stakes. A neighbouring lunar settlement needs additional oxygen capacity. An invoice is issued and payment has to be settled between two operators, making it an infrastructure purchase.

Which currency are we even talking about? US dollars? Euros? A shared lunar unit of account? A decentralized space‑wide token?

The 1967 Outer Space Treaty prevents any nation from claiming the Moon. From a payments perspective, that instantly complicates ownership, regulation and currency. Projecting multiple national currencies into that environment would mean constant conversion, overlapping rules and political friction.

The group broadly agreed that Earth‑based national currencies would be impractical in space.

 "Having a single agreed currency for space just makes more sense than trying to use Earth currencies", Adam added.

So what would a “moon‑native” currency actually look like? Two broad models start to emerge:

• A space‑wide currency used across multiple colonies.
• Local lunar or planetary economies that only interface with Earth when value is redeemed back.

In both cases, taxes, fees and conversion might happen at redemption, not at the point of transaction.

Whatever the model, payments themselves would almost certainly be offline or delayed by default.

"Payments in space would probably be offline by default. Every transaction would be store and forward", Adam said.

This raises new challenges around fraud, reversals and dispute handling.

And yet, it’s not entirely alien. Cross‑border energy contracts and infrastructure billing already operate across currencies, time zones and delayed settlement cycles. Trust there is as much contractual as it is technical.

But what happens when we add another layer: movement of goods, people and resources across a wider network?

Now that we have laid the groundwork, it’s a good time to extend the scenario beyond B2C, as Martin says: “For the foreseeable future, space payments will mainly be B2B.” Let’s have a go at another hypothetical then...

A lunar mining operation contracts with a Mars‑based logistics provider to move extracted materials. Payment terms span planetary distance.

Latency stops being a minor delay and becomes structural. Real‑time authorization effectively disappears, as settlement is asynchronous by design.

Mining rights, logistics, resource extraction and infrastructure services are likely to dominate early space economies. Consumer payments, while present, are secondary.

Fraud detection has to cope with delayed data. Transaction reversals and refunds become slower and more complex.

Martin drew an interesting parallel: “We already see this problem on Earth with EV charging and fragmented payment experiences.” Drivers move between operators. Authorization depends on device‑bound credentials. Settlement is handled later between networks.

Space introduces the same tensions, just with more distance:

• Multi‑operator environments
• Device‑bound identity
• Delayed or offline authorization
• Cross‑network settlement by default

As Martin noted, “Every time something new appears, people try to reinvent everything instead of simplifying.” 

So the question becomes: if you had to start from scratch, what would you actually keep?

Strip everything back, and the fundamentals remain

If you remove terminals, cards, instant connectivity, and national currencies, there are still some fundamentals that must remain...

• Identity must be verifiable
• Authority must be recognized
• Currency must be agreed
• Settlement must be trusted
• Disputes must be resolvable

Physical POS terminals score badly against that list in space.

"Shipping physical POS terminals to space feels like the least practical option imaginable", Adam said.

In that context, person‑to‑person or device‑native payments start to make far more sense than traditional merchant terminals.

“If we were starting again from scratch, I would push tap‑to‑pay everywhere”, Adam added.

Biometrics look likely to play a major role, especially if payments are embedded into suits or wearables. “Biometrics feel like the future, whether people are comfortable with that or not”, Adam said.

But that future comes with familiar questions around:

• Privacy
• Accessibility and edge cases (for example, amputees)
• Extreme crime scenarios, including biometric coercion

Any biometric‑heavy approach would need multi‑factor safeguards. Liveness checks, contextual signals and additional layers are required to stop abuse.

And through all of this, there’s still a human angle. "Shopping is also entertainment. If everything becomes invisible, we lose something human", Martin said.

Payments are technology layered on top of behavior, so the rails may change but the incentives do not.

Bringing it back down to earth...

Now we’ve played out the hypotheticals of lunar meals, oxygen invoices and interplanetary logistics, what does any of this say about the way we run payments down here?

If a system has to work on the Moon, why are we still tolerating so much friction on Earth?

And if we were starting from scratch today, would we really rebuild what we have now?

Space payments will almost certainly use new rails and new technology. They’ll still have to navigate human, political and economic tensions. And over time, they’ll probably recreate many of the patterns we already know.

The difference is that on the Moon, you can’t hide behind legacy, you have to decide what really matters.

Well, maybe that’s the real value of this thought experiment: once you’ve designed payments for somewhere as unforgiving as the Moon, it gets a lot harder to accept second‑best back on earth.

And if that’s true, then orchestration goes from being a nice-to-have to actually essential.

If you’re ready to explore how orchestration can support “any payment, anywhere, any device” in the real world, let’s talk.
