- slipperlobster 3y agoOne of the huge pain points I was responsible for was certification of certain payment terminals. Meaning, hardcoded PANs (personal account numbers) written to magnetic stripe cards (or, worse, EMV chips) that have to make physical contact with a reader to transmit data. Up until a point, we were able to (easily) reproduce these messages via the ISO8583 message format via software. Makes certification much more automation-friendly. Once we got into hardware encryption/decryption via HSM devices, it wasn't as easily done.
