General-About this model, the Bank of China is CH, the American version is LL, the Japanese version is J, and the Hong Kong version is ZP. If it's not CH, it's definitely not China Bank.

The blue label of the Ministry of Industry and Information Technology will be posted on the back of the new machine of China Bank, which is unique to China Bank. When illuminated by a money detector, a clear and bright watermark will appear, which is as anti-counterfeiting as paper money.
