Please ensure that all your card details have been entered correctly and the card is still valid.
Please ensure using a debit/credit card powered by Visa/Mastercard.
If you are still experiencing issues, please consider contacting your bank to ensure your card is authorised for online transactions or try linking another card.
Some banks such as ADCB and ADIB do not permit debit cards to be used for online transactions. Unfortunately, this means that some cards cannot be linked to your Beam account :(
