How far does light travel in 2.5 seconds

According to what the author expresses in this excerpt, in order to confirm the authorship of a document, handwritten ink signatures should be present. Otherwise, there would be no reliable way of verifying the source of that document.

Explanation:

The main reason for Simon Singh to believe that is that, if we don't have a handwritten signature, we could be easily fooled by criminals who take other people's names to make us do things for their own benefit, like in the example given by the author of the bank account. I think his claim is pretty accurate and that the example given by the author supports the claim in a very logical way. I, in fact, agree with him in believing that handwritten signatures or any other way of pursuing reliability is worth the time and intention. Nothing is too much when trying to avoid fraud, and I also think it is a good practice to update the protection system every now and then to maintain our information private and secure.
