The turmoil in South Africa seems to have thankfully subsided. The situation is still tense with sporadic acts of violence and looting. However, the situation seems to be much better compared to what we witness over the past few weeks-pure anarchy. A lot of looting took place during that time and some ATMs were bombed and money was taken from them. It seems those who took this money are now trying to spend it.

You shouldn’t accept the looted money. If anyone tries to pay you using dye-stained South African Rands you should refuse them. According to South African authorities, such notes are not legal tender. The notes are likely the proceeds of a crime.

ATMs hold cash in special containers protected with dye-stain technology that is activated when someone tries to break open the container.
Once activated, the cash is stained with a green dye, thus defacing the notes, rendering them unusable as currency.
The stained notes are recognised as having no monetary value once they are stained.

Accepting those notes means you become a party to that conspiracy. If that doesn’t deter you remember that such notes are no longer legal tender. You cannot for example use them to buy goods in other shops or deposit them into your account. Whatever bank you approach will refuse them. So it’s no different from you accepting fake notes. Do not do it.

You should be careful, why some notes are obviously stained sometimes some notes only get a bit of ink that might not be easily seen unless the note is inspected closely. You should make it a habit to examine each note you get carefully.
