You won’t be able to pay at a petrol pump with your GBP Monese card, because this feature is only available for EUR cards. Instead, you can take your GBP card straight to the cashier to pay for your petrol.
There are also some airlines which do not accept debit card payments in-air so be sure to withdraw some cash if you need to spend money mid-air.
There are also a number of merchants that Monese will not allow to be processed and such merchants may be blocked if they fall into certain categories. These include:
Dating and Escort Services including advertising services
Automated Fuel Dispensers
Quasi Cash Services
Cryptocurrency traders like Bitcoin trading platforms*
POI Funding Transactions
*Monese is actively pursuing ways to enable this in a secure way
