There are several reasons why your transaction may have declined, these include:  

  • You may not have enough money in your HyperJar account
  • You have entered the incorrect details (PIN, CVV, Expiry date)  
  • Your card is blocked because the PIN has been entered incorrectly three times. If this is the case, please start a Live Chat and we can help unblock it
  • Your card is frozen
  • Your card has expired
  • Your card is damaged
  • The merchant does not accept Mastercard payments
