• 0:23 = epic﻿ face

• 250 different types of combination? Check your math.

This guy pressed 5 buttons for his password and there are 5 possible letters to choose. So, a permutation with repetition would mean that there were 5^5 possible combinations or 3,125 possible codes.﻿ Make your code 6 letters long and that jumps to over 15,000 possibilities.

• Sorry? I don't think those numbers mean what you think they do. They are just there so you could in theory have a password that's "918918918". In﻿ order to type that, you just type in EAEEAEEAE. You don't type E twice to get 9, or A to get 1, you just press it once.

• Try opening your eyes before trying to show off math skills on youtube. If you look at the card you can see that each﻿ letter "A-E" has two numbers under each so there are 9 numbers to combine.

• Bagsy﻿ my card doesn't need batteries to work.

• you fail to see the meaning in my comment --- if all your info is in ONE PLACE on ONE CARD -- and you LOSE THAT CARD...youre royally screwed.

• You mean just like if you lost your wallet? If you're the type to lose things just get the security one that was discussed﻿ in the video. You lose it, no problem!

• Who else noticed the big triangle symbol﻿ on the top of the card? hmm.. i bet £100m somebodys gonna makes a video about illuminati including this ._.

• soo...if someone loses that or misplaces it... they're screwed﻿ because all of their info is in one place

ingenious idea!

• It's acutally 10 buttons...look closer at it. An account digit can be 0-9, what you're doing is typing in the missing digits of the account (we'll call it a long﻿ PIN number), I would guess it's like texting on a non-QWERTY pad, if you wanted a "B" you hit "1" twice. Looks similar here, if you want a "1", hit the first button twice, a "4" hit the third button once, etc.
