Paying Online With Cash: How Notes Become Balance

There is no way to send a banknote through a browser. Every method that claims to let you “pay online with cash” is really doing the same thing underneath: converting the cash once, in advance, and then spending the result.

Understanding that split is what makes the rest obvious — including the limits, which are not arbitrary but follow directly from the mechanism.

Why paying online with cash needs two steps

A card payment is a single event with a promise attached. You hand over a number, the merchant asks your bank whether the number is good for the amount, and the money moves later.

Cash has no such promise built in. It settles on the spot and carries no identity. That is its strength in a shop and its weakness on the internet, where there is no counter to hand it across.

A voucher bridges the two by breaking the payment in half:

1. The cash leg. You pay for a code, and the code is worth what you paid. This happens once, separately from any purchase.
2. The online leg. You spend the code at a checkout. No bank is involved, because the money was already settled in step one.

Everything else follows. The code is single-use because cash is single-use. The amount is fixed at purchase because a banknote’s value is fixed when it is printed. There is no chargeback because there is no promise to withdraw.

What the CashtoCode eVoucher actually is

A 20-digit alphanumeric PIN, delivered by email, valid once.

It is bought from an authorised online reseller rather than picked off a shelf. The value is set when you buy and cannot be topped up afterwards — if you need more, you buy another code. The currency is locked to the code at purchase, and it is available in more than 25 of them.

At the merchant’s end, one PIN settles exactly one transaction at exactly one merchant. Most partners let you combine several codes by entering them one at a time, but a single code cannot be split across two merchants, and an unspent remainder does not come back to you as change.

That last point is worth planning around. If you want to deposit 80 and hold a voucher worth 100, you are not getting 20 back. Match the denomination to the deposit. Our page on CashtoCode eVoucher denominations lists what is actually in stock per market.

What it costs

Nothing, in the ordinary case, and the detail matters more than the headline.

We never charge the end user. The merchant credits the full face value with no deduction on redemption. There are no maintenance fees, no monthly charges, and no erosion of an unused balance over time — a genuine difference from some prepaid cards, which quietly reduce a dormant balance month by month.

Two things can still cost you money, and both are outside our control:

• A small number of crypto-focused resellers add a handling fee, typically 1 to 5 percent, disclosed before you buy.
• Currency conversion is performed by the merchant at its own rate when the voucher’s currency differs from the merchant’s base currency. Buying in the merchant’s currency avoids this entirely.

The full breakdown is on the CashtoCode eVoucher fees page.

Where cash still sits in the payment mix

It is easy to argue from either extreme here — that cash is finished, or that it is quietly winning. Neither holds up.

By transaction count, cash is still the largest single method at the euro-area checkout, though it slipped below 52 percent in 2024 from 79 percent in 2016. By value, worldwide and in store, it accounted for 15 percent in 2024, down from 44 percent a decade earlier.

Those two figures look contradictory and are not. One counts payments, the other counts money. Cash is used for many small purchases and few large ones, so its transaction share will always sit well above its value share. Anyone quoting one without naming the basis is, knowingly or not, making the trend look steeper or flatter than it is.

The practical consequence for online payments is narrower than either number suggests. Cash is not competing with cards at the checkout — there is no cash option there to compete with. It competes with the question of what you do when a card is unavailable, unwanted, or would put a line on a statement you would rather not create.

Where the method stops

An honest guide names the ceiling. Three of them apply here.

It only goes one way. CashtoCode is a deposit method. Payouts need a separate method the merchant supports, usually a bank transfer or an e-wallet. Sort that out before you deposit, not after — some merchants will not release a payout until the receiving method has been verified, and that verification takes longer than the deposit did.

The merchant network is narrow by design. Online casinos, sportsbooks, crypto exchanges, VPN and hosting providers, gaming marketplaces and dating platforms are in. General retail is not — no Amazon, no eBay, no supermarket delivery. That is a commercial positioning decision rather than a technical barrier, but the practical effect is the same: check the merchant’s own live payment page, because third-party acceptance lists go stale quickly.

A code behaves like cash once it leaves your hands. Whoever holds the PIN can redeem it, and a redeemed code cannot be recovered. An unredeemed one can usually be refunded through the reseller under its own terms, commonly within 14 to 30 days. Our CashtoCode eVoucher refund page sets out which case is which.

One product, two forms — check which one applies to you

This trips people up often enough to state plainly. What we sell is not the same everywhere.

Outside Germany, Austria and Switzerland, it is the eVoucher described on this page: buy a PIN, enter the PIN. Inside those three markets it is a different product entirely — a barcode generated at the merchant’s own checkout, taken to a partner outlet and paid for in cash there, with nothing bought in advance.

Neither is a variant of the other; they are separate products serving separate markets, and markets have moved between them in both directions. The merchant’s live payment page is the authoritative answer for where you are today. For what the international product is in detail, see what is the CashtoCode eVoucher.

Is this the right method for you

It fits when the deposit is a one-off, when the amount is modest, when you would rather not hand a card number to a merchant you have no ongoing relationship with, or when you simply do not hold a card that the checkout accepts.

It fits badly when you need the money to come back the same way, when the amount is large enough that stacking codes becomes tedious, or when you are buying from ordinary online retail, where it is not offered at all.

That is a narrower recommendation than most payment pages will give you. It is also the one that leaves you with fewer surprises at the checkout.
