If you are unsure whether or not fraud has occurred, here are some tips to help you decide whether or not you recognise a transaction*:

  1. Could it be a subscription from a recognised merchant? Sometimes when making a purchase, a company may require you to sign up for a subscription or trial in their small print to provide you with a service or to complete check out. The easiest way to cancel a subscription is to contact the provider directly.
  2. Is the company's trading name different to the business name? In some cases businesses may use different names to trade with than their main business name, for example if you make a purchase with Argos, it may show on your statement as 'Home Retail Group' because this is the name of their parent company. It's always worth looking up the name of the company which has charged you. 
  3. Do you recognise the merchant but not the time and date? When you make a payment, it can take a while for the company to complete the transaction. When you authorise a payment, OnePay will reduce your balance right away ready for the funds to be taken by the merchant so that you don't overspend but it can take up to 7 days for the funds to be claimed. Therefore, if you made a payment at Tesco on a Thursday it may show as the following Wednesday's date on your transaction history because that's the day the transaction was completed. 

* We recommend keeping your card locked via the 'My OnePay' App or Online Portal whilst you make these checks and until you are sure that no fraud has taken place on your account.
