Oh dear. You can’t even trust your photocopiers these days. Spot the difference.
The implications are huge. Imagine what happens if the following happens as a result of your copy getting messed up (excerpt from article):
- Incorrect invoices
- Construction plans with incorrect numbers (as will be shown later in the article) even though they look right
- Other incorrect construction plans, for example for bridges (danger of life may be the result!)
- Incorrect metering of medicine, even worse, I think.
