- sandworm101 4y agoGlad to see that my 6-digit pin is safe from hacking for at least a few more years.
- bomdo 4y agoDon't be so sure of that. If your PIN just happens to start with 00, it is fairly trivial to jury-rig a common 4-digit hacking device to crack your 6-digit PIN.

- forinti 4y agoIn 2009 my card had a 6-digit PIN and I went on holiday to Argentina. The card readers there only accepted 4 digits and they validated my card with the first 4 digits of my PIN. That was a bit disconcerting.
- hardware2win 4y agoWhat the...? Its crazy, but kinda reasonable
- sgjohnson 4y agoPIN is actually completely optional. A rogue terminal can decide to authorize the transaction with a “signature” (there are legitimate uses for this) Or even with no PIN at all (there are also legitimate uses for this) It’s also possible to do either of these 2 things and then report back that the transaction what authorized with a PIN
- Goz3rr 4y agoOn that subject, I (a European) went to the US last week. It was time to pay at a restaurant in their needlessly complicated way where they hand you the bill, you return them the bill with your card and then they return once more for you to fill out the tip. Shortly after the second step the waiter returned apologizing, saying they could not bypass the PIN on the card like they normally could (which was slightly startling to me) and asked if I could come with them to enter it on the payment terminal myself.
- sgjohnson 4y agoMust have been a debit card that flat out refused anything but Chip & PIN. Most cards aren't like this. With my UK issued AmEx & Visa cards (both Charge/Credit), at certain places terminal didn't even ask me for a PIN, and the transaction just went through as "Chip & Signature"
- dzhiurgis 4y agoUp in Lithuania they now starting to have a contactless tipping device where you scroll the wheel to select tip amount. Which is kinda pointless since if you are paying and receiving service at the counter - you aren't really receiving a service to tip for.
- saiya-jin 4y agoSame experience (card came with default 6-digit pin that I didn't change), never have longer-than-4 pin when traveling outside of western democracies. The fact that it worked made me doubt that it was actually verified, but didn't have balls to play with this too far away from easily obtainable money
- notafraudster 4y agoThis is why my PIN is 9998.
- vorticalbox 4y agoI believe most banks stop sequence numbers such as "1234", "9876"
