Recently i had deposited 85£ on my prepaid mastercard to pay off my ACCA subscription fees. After meeting those expenses, i know that my balance on my prepaid card should be almost nil. But whenever i'm making more purchases online, payment is getting approved via paypal. I went to the the ATM and i check my balance which was less than $1. After reaching home, i bought an another item on ebay worth $15 using the same card just to cross check. The payment got approved despite my balance was less than $1 on the account. How is it that my payments are being approved?
P.s There's no question of an overdraft here because my prepaid card do no allow this service.
