....It is at least like this with my card.
I live in Canada, my bank is BMO, I don't know a bout the others banks/countries
The mag strip is easy to copy, there were a big network of thieves that place modified terminal (with the complicity or merchants or their employees). The modified one copy the card (mag strip), by reading directly what the magnetic head reads, and the PIN by placing a pad between the buttons and the PCB.
I had, my card cloned twice, when I had the only the mag strip. Now? 0 times. If the merchant's terminal doesn't have the chip I don't use my card (the bank will refund me, but the hassle is not worth it -both times my card was disabled Friday evening, and my branch is closed for the weekend-).
If the terminal support the chip, my mag strip won't work anyways , so using it will only expose me to the risk of a cloned card and the hassle that comes with it (may be the merchant/clerk did something to the machine to force people to swipe the card, may be not, nothing to gain in trying).
With that said, I change it at least once a year, b/c at some point it starts acting funny (and it's free)
lol you should google your sig made me laugh even though i havent a clue what your sig really means i had to search it.
1^2=1; (-1)^2=1; 1^2=(-1)^2; 1=-1; 1=0.
^ this? what's so funny about it? (there's an error/catch, obviously)
You buy into the fad that equal means same
equivalent (as in mathematical equivalence relation, mind you "equal" is one) would be more suited
To thine own self be true. (If not that, at least make some money.)
