Nowadays, a high end Multipurpose Laser Jet Printer can print RM100 note and looks almost 98% the same as the real one. Just that the texture of the paper different. Due to RM100 not a polymer note so very hard for us to differentiate the real and fake ones.

Plus those con man will print with different serial numbers too. So the safer way to do COD is the nearest bank and as him/her to bank in to your account. Do this if he/she take out more than 1 Rm100 notes to pay for the item.

Not every ATM dispense RM100 notes, i can assure you that but HSBC ATM does have special machine to dispense RM100 notes. I usually choose to withdraw with RM100 notes at HSBC's because sometimes i withdraw more than 3k at once. So my wallet wont get so thick after withdrawal.

Nowadays RM20 and RM10 also have fake notes...beware.
