I respectfully disagree. As people said before, Pascal is an old and dying language. Those used to be written in Pascal almost all replaced by C++ and Java. C++/Java (and other new languages) are clearly much more secure than Pascal. You can write a coin using Fortran, as people did in the eighties, nothing wrong with it, the coin can still work. But I will say that it's a bad choice, why? because it will be difficult to be maintained, enhanced, or linked/interfaced with latest web and internet based environment.
