The Central Bank has sent a rush letter to all banks, warning them against an illegitimate Chinese pen, dubbed the “magic pen,” which it tells might be utilized to forge documents with its disappearing ink. They say that the ink will fade after an hour and can last maximum to four days. People should be aware of this especially banks’ staff who deal with lots of clients each day.
However I really don’t know how this will work, will the staff ask the customer to check his/her pen which will lead to a huge argument I guess or banks will provide the customer with a pen to sign any banking document?
Well this should be taken seriously!
