MICs are usually mentioned in the same sentence that also explains why you can't print nor scan money.
The big Wikipedias have long articles on it with many sample images: https://de.wikipedia.org/wiki/Machine_Identification_Code https://en.wikipedia.org/wiki/Printer_steganography
or a Florida birth certificate (WTF?)
If you need to fax one, you'll need to find a really old fax machine without color printer or scanner capability.
