A lady surnamed Xu in Jiaxing, east China's Zhejiang province has met with an unpleasant surprise lately as she withdrew 3 pieces of paper from a local ATM and later found out they were test notes.

The three pieces of paper came from a Bank of Communications ATM and they were the same size of the 100 yuan note bearing the words read "test note" on them.

Xu was confused at first and called the police, the police officers confirmed the paper did come out the ATM but said that they had also never seen such a thing before.

After contacts with the staff members of the local Bank of Communications branch, the 3 pieces of paper were said to be test notes put into the ATM by the maintenance workers.

According to a maintenance worker of the ATM, the paper is to test if the machine is working properly after their repair work, as they are not allowed to use real bank notes to do the test work.

However, it is the staff members of the bank who are responsible for removing the test notes after the repair work is done.

The local branch of the Bank of Communications have promised to returned Xu the real 300 yuan and give Xu a proper response after checking their working procedures.

Insiders of ATM workings revealed that the bank should take most of the responsibility for the incident as there were clear working regulations on repairing and adjusting the ATMs. He also noted that as the test paper is specially designed, other kinds of regular paper will not be deposited through the ATMs.
