What Is Curve?
Curve is a free mobile wallet and card that lets you connect all your existing debit and credit cards into one single card.
Instead of carrying 3–5 different cards, you just carry the Curve card and choose in the app which card sits behind it.
Think of it as a smart layer between you and the shops you pay.
- Add your Visa and Mastercard cards into the Curve app
- Use the Curve card in-store, online, or contactless
- Curve routes the payment to the card you selected in the app
- You get extra perks like cashback, FX savings and “Go Back in Time”
How Curve Works (Simple Explanation)
- Download the Curve app on your phone.
- Add your existing bank cards (debit or credit).
- Curve gives you a virtual card instantly and a physical card in the post.
- When you pay with Curve, it charges the merchant and then passes the transaction to whichever card you selected in the app.
- You can view every transaction inside Curve, change cards for future payments, and sometimes even move a past payment to a different card.
Result: you keep using your usual bank, but with more control and more rewards.
Key Features That Make Curve Worth Using
1. Go Back in Time 🕒
Accidentally paid with the wrong card? Curve’s Go Back in Time feature lets you move a past transaction to another card (within Curve’s time limit, usually up to 30 days).
Examples:
- You used your debit card but wanted to use your credit card for points – move it later.
- You paid from the wrong account – switch it to the right one.
This is one of Curve’s most powerful tools and a big reason many people use it daily.
2. Cashback at Popular Stores 💸
Curve can give you instant cashback when you spend at selected shops, restaurants and online services (think Amazon, supermarkets, streaming and food delivery). Your cashback is paid into your Curve Cash balance, which you can then spend with your Curve card.
With my invite link, you get an extra 1% cashback for your first 30 days. More on that in the referral section below.
3. Save on Foreign Transaction Fees 🌍
When you travel or buy in foreign currency, many banks charge ~3% in FX fees. Curve helps you:
- Reduce or avoid foreign transaction fees (within Curve’s fair usage limits)
- Get more competitive exchange rates compared to many traditional banks
If you travel or shop on international websites, this can save you a lot of money over time.
4. One Card to Rule Them All 🔐
Instead of carrying lots of cards, you carry only Curve. In the app you can:
- Switch which card you pay from in a couple of taps
- Lock the Curve card instantly if you lose it
- See real-time notifications for every transaction
Your real bank cards stay hidden behind Curve, adding an extra layer of privacy and security.
Who Is Curve Good For?
Curve might be a great fit if you:
- Use multiple bank cards and want to simplify your wallet
- Like to earn cashback and rewards
- Travel abroad or shop in foreign currencies
- Want more control over which card is charged
- Enjoy organizing your spending in one clean app
If you mostly pay by card and shop online, Curve can quietly save you money in the background.
How the Curve Referral Bonus Works (1% Cashback for 30 Days)
Curve often runs referral promotions. With the current promotion at the time of writing, if you sign up using my referral link, you get:
➡ 1% cashback on eligible purchases for your first 30 days.
How to Get Your Bonus
- Click my Curve invite link:
👉 Join Curve & Activate Your 1% Cashback
- Download the Curve app and complete registration.
- Add at least one of your existing bank cards.
- Order your Curve card if needed and start using Curve for your everyday spending.
Once your account is active and you start using Curve, you’ll earn 1% cashback on eligible purchases for up to 30 days (according to Curve’s latest promo rules). Cashback is paid into your Curve Cash balance, which you can then spend using the Curve card like normal money.
How Much Can You Earn?
It depends on how much you spend during the bonus period. For example:
- Spend £300 in 30 days → 1% cashback = £3 back
- Spend £500 in 30 days → 1% cashback = £5 back
- Spend £1,000 in 30 days → 1% cashback = £10 back
That’s on top of any rewards or cashback you already earn from the underlying bank card, so you can effectively stack rewards.
Note: Referral bonuses and cashback limits can change over time. Always check the latest details inside the Curve app or on their website.
