Two years ago I had an incident where a transaction went off my credit card with "Bank A" and then immediately afterwards a reversal SMS came through. I didn't waste anytime and as I was driving at the time I immediately diverted to a Standard Bank office where they promptly cancelled the card and placed an order for a new card.

This evening the same thing happened again with "Bank B". My questions are:

What is the nature of these transactions?
How are they possible?
How does the bank know to reverse them within seconds without my input?

Does anybody have experience with this?
 
often...

scammers got your details
they transact for a few rands,
then they reverse (test working card), merchant reversal.
then either the same day, or within days, they hit hard...
