Protecting yourself from fraud
Fraudsters are becoming increasingly sophisticated, but a few simple checks can keep your money safe.
If you think your card or details have been compromised, contact us immediately. The sooner you report it, the better we can protect you.
We will never ask for your PIN, full card number, or one-time passcode.
Types of fraud to watch out for
Understanding one-time passcodes (OTPs)
An OTP is a unique code sent by us via text message or app notification to verify that it’s really you making a transaction or logging in. It expires within minutes and can only be used once. This makes it one of your strongest security tools – but only if you keep it private.
Fraudsters often pose as Radius staff, delivery companies, or HMRC and claim they need your OTP to “verify your account” or “process a refund”. Never share it - this is always a scam.
How to protect yourself from fraud
Guard your PIN at all times
Always cover the keypad when entering your PIN at ATMs or shops – even if no one appears to be watching. Never write your PIN down or store it near your card.
Never share one-time passcodes
No one from Radius, or any genuine retailer or support agent will ever ask you to read one out or forward it to them.
Only shop on trusted websites
Look for the padlock icon and “https://” in the address bar before entering card details. Avoid clicking links in unsolicited emails or texts to make purchases.
Review your statements regularly
Check your account frequently for unfamiliar transactions and report anything unusual straight away.
Never share details over the phone
If you receive an unexpected call claiming to be from us, hang up and call back using the number on the back of your card. Genuine callers will understand.
Enable transaction alerts
Turn on instant notifications for every card payment so you’re alerted the moment your card is used. This lets you spot and report fraud within minutes.
