my new woolworths rewards card has been hacked, points already used in other state while i only received today
Applied the card last month with 5000 points bonus, i received the card today, login, and found the points were used in other state two weeks ago.
Anyone same situation with me? Who can access the card number before me? The envelope received today sealed in a unopened condition.
Possibly someone ordered a bunch of Woolworths Rewards cards, noticed a pattern in how they are numbered, created barcodes for the next numbers in the sequence and used them to redeem your points.
It's entirely possible that for Woolworths rewards they just increment each member number by 1, and because the membership number is also a barcode, the only security in it is knowing the last number is a check number.
E.g. My card could be 9353000000008 and the next person would be 9353000000015
