In plain words
Think of the chips at a casino. You hand over £100 and get £100 of chips. You can use them inside, and when you leave you can swap them back for exactly £100. Now imagine those chips also work in shops, can be sent to friends and never lose their value. That is roughly what e-money is.
E-money, short for electronic money, is a digital balance that a licensed firm gives you in exchange for real money, one for one. In the UK the law describes it as monetary value stored electronically, which is a claim on the issuer, issued when it receives funds, and accepted by other people for payments. 1
In practice, it is the balance you see in many wallet and neobank apps. If the app runs on an EMI licence rather than a banking licence, your “money in the app” is e-money. The real pounds or euros behind it are held in a safeguarding account, and you can ask for them back at any time.
How it works
How e-money works
Issued, used and redeemed, always at face value.
-
1
Issue
You pay £50 into the app. The issuer creates exactly £50 of e-money in your name. No discount, no bonus that depends on how long you keep it.
-
2
Protect
The issuer keeps the £50 separate from its own money. It cannot lend it out or pay you interest on it.
-
3
Spend or send
You pay by card, transfer to a friend or pay a bill. Your e-money goes down and the protected money moves with it.
-
4
Redeem
Whenever you want, you withdraw what is left to your bank account at face value. The law sets strict limits on any fee for doing so.
The three rules that define e-money
Issued at par
You get exactly the value you paid in. The issuer cannot issue £105 of e-money for £100. 2
Redeemable at par, any time
You can turn it back into ordinary money at face value whenever you ask.
No interest
Issuers cannot pay interest or any benefit linked to how long you hold the e-money.
Not every prepaid balance is e-money. Value you can only spend with one retailer, such as a single shop’s gift card, or inside a limited network, is usually excluded. The line can be thin, so check before you design a closed-loop wallet.
E-money vs bank deposits vs stablecoins
Three things that all look like “a balance in an app” but work very differently underneath.
| E-money | Bank deposit | Fiat stablecoin (EU EMT) | |
|---|---|---|---|
| Who issues it | An EMI, or a bank | A bank | An EMI or a bank, under MiCA |
| Where it lives | The issuer’s ledger | The bank’s ledger | A blockchain |
| Can the issuer lend it out | No | Yes | No |
| Interest | Not allowed | Allowed | Not allowed |
| Protection | Safeguarding | Deposit insurance up to a limit | Reserve and safeguarding rules under MiCA |
| Redeem at face value | Yes, any time | Yes, subject to account terms | Yes, any time |
In the EU, a stablecoin that tracks a single official currency is an e-money token, or EMT. MiCA treats it as e-money, so only banks and EMIs can issue it, and it carries the same no-interest rule. 3 The UK is building its own stablecoin regime; we cover where it stands in the UK stablecoin moment.
What it means for product design
The e-money rules are short, but they shape a lot of product decisions.
- Balances must be exact. Every penny issued must match money received, and every redemption must pay out at face value. Rounding errors and pending states need clear rules.
- Withdrawals must be easy. Customers have a right to redeem. Hiding the withdraw button or adding surprise fees is a regulatory problem, not just a UX one.
- Rewards need care. Cashback on spending can work. Anything that grows with the size or age of a balance looks like interest.
- Wording matters. Calling e-money a “deposit” or a “savings account” misleads customers about how it is protected.
UK, EU and Gulf
| Market | What it is called | Who can issue it |
|---|---|---|
| United Kingdom | Electronic money | Authorised and small EMIs, banks and a few other named bodies, under the Electronic Money Regulations 2011 |
| European Union | Electronic money, and e-money tokens on a blockchain | EMIs and banks, under the E-Money Directive and MiCA |
| UAE (mainland) | Stored value | Firms with a Stored Value Facility (SVF) licence from the CBUAE |
| Saudi Arabia | Electronic money | E-money institutions licensed by SAMA |
The UAE’s stored value rules are not a copy of UK e-money rules. See when a wallet product triggers heavier regulation in the UAE.
Example: a student wallet
Leo’s parents top up his student wallet app, which runs on an EMI licence.
- Top-up. His mum sends £200. The EMI issues £200 of e-money to Leo and places the £200 in its safeguarding account.
- Spending. Leo spends £120 over the month on his card. His balance shows £80.
- No interest. The £80 earns nothing while it sits there. That is the law, not a choice by the app.
- Cash out. At the end of term he withdraws the £80 to his bank account. He gets £80, at face value.
Common misconceptions
“E-money is a kind of crypto.”
No. Most e-money lives in an ordinary database. Only e-money tokens use a blockchain, and they follow the same core rules.
“My app balance is a bank deposit.”
Only if the app runs on a banking licence. On an EMI licence, it is e-money, protected by safeguarding, not deposit insurance.
“We can reward customers for keeping a balance.”
Not with interest or any benefit tied to how long they hold e-money. Rewards need careful design and legal advice.
FAQ
What is e-money?
E-money, or electronic money, is a digital balance issued by a licensed firm in exchange for real money, one for one. It can be used to make payments to others and the holder can turn it back into ordinary money at face value at any time.
Is e-money the same as money in a bank account?
No. Money in a bank account is a deposit that the bank can lend out, and it is covered by deposit insurance up to a limit. E-money cannot be lent out, pays no interest, and is protected by safeguarding instead of deposit insurance.
Is e-money safe?
Electronic money institutions must safeguard customer funds, keeping them separate from their own money so they can be returned if the institution fails. E-money held with an EMI is not covered by the UK FSCS, so the protection depends on the EMI keeping that separation correctly.
Why does e-money not pay interest?
The law forbids it. In the UK and the EU, e-money issuers cannot pay interest or any other benefit linked to how long the customer holds the e-money.
Who can issue e-money?
In the UK and the EU, e-money can be issued by electronic money institutions, banks and a few other bodies named in the law. Issuing it without the right permission is against the law.
Is a stablecoin e-money?
Some are. In the EU, a stablecoin that tracks a single official currency is an e-money token under MiCA, is treated as e-money, and can only be issued by a bank or an EMI. Other stablecoins fall under different rules.
Are gift cards and store cards e-money?
Usually not. Value that can only be spent with one retailer or within a limited network is excluded from the e-money rules, as long as it stays within that limit.
