1.) throw your card in the microwave for no more than 3 seconds. This will completely damage the chip.
2.) recode your magstripe information with a valid dump; preferably with matching last four cc digits.
3.) insert the chip in POS 3 times and that will activate a swipe request. Swipe the card to purchase.
4.) keep in mind POS security/authentication varies - even a valid card might get declined.
