I wonder if we will see this in the near future. RBC are releasing some or all of their new credit cards with to be used by PayWave systems, which is convenient, but does not make sense when you have chip&pin on the card to stop people from using it. Even with the chip&pin security, the card can still be entered manually and be used. One thing I would like for Canadian banks to start handing out security keys for bank accounts. Instead of having to update your password or remembering it when you go online. The key has a randomly generated password you need to use to access your account online. Only person I have seen something like that was my ex. http://en.wikipedia.org/wiki/Security_token

I had a midterm examination in my stats/probability class yesterday (yes on a Sunday....). I'm trying to figure out if I got the right answer or not on one of the questions. Everyone had problems with this question it seemed. Yet the question seems pretty simple on the surface! The question was about the number of coffee refills ordered at a truck stop. # of refills | Probability 0 | 0.3 1 | 0.4 2 | 0.2 3 | 0.1 a) What is the probability of two randomly selected truckers will each order the same number of refills? I put: (0.3) (0.3) + (0.4)(0.4) +(0.2)(0.2) + (0.1)(0.1) = 0.09 + 0.16 + 0.04 + 0.01 = 0.3 Is that correct? Thanks!
