Recently I received a promotional mail from LinkedIn for trying out 1 month free of Premium membership I accepted the offer and as was required I provided my credit-card details.
I have done a plenty of Online Transactions on my card but every other time I did an online transaction I needed to provide a password before money was deducted from my account.
This time I did not provide my password (It was not asked) but still LinkedIn was able to reduce Re 1 from my account. I do not doubt the credibility of LinkedIn but was shocked to see how money was deducted from my account even without giving my online transaction password.
Please let me know How was LinkedIn able to deduct money from my account?
