Agreed and this is something that you can't say you are aware of because banks do not communicate of internal security measure checks. As an example : I paid 1c

Agreed and this is something that you can't say you are aware of because banks do not communicate of internal security measure checks. As an example : I paid 1c on my own website via paypal while doing paiement integration test, and the transaction was blocked. I received a text message that told me to call the bank to authorize the paiement. I asked if it would block again for another test, but they have consigns to not answering that kinds of questions and I'm glad they did ;)
