Chapter 4:Fortunately, it wasn't always possible to rely on normal electronic transfers, even when both parties to the transfers in question were as pure as the new fallen snow. Which was why physical fund transfers were still possible. As the female crewmember stepped forward, Hutchins punched in the combination to unlock the battle steel box, and its lid slid smoothly upward. Inside were several dozen credit chips, issued by the Banco de Madrid of Old Earth. Each of those chips was a wafer of molecular circuitry embedded inside a matrix of virtually indestructible plastic. That wafer contained a bank validation code, a numerical value, and a security key (whose security was probably better protected than the Solarian League Navy's central computer command codes), and any attempt to change the value programmed into it when it was originally issued would trigger the security code and turn it into a useless, fused lump. Those chips were recognized as legal tender anywhere in the explored galaxy, but there was no way for anyone to track where they'd gone, or—best of all from the slavers' perspective—whose hands they'd passed through, since the day they'd been issued by the Banco de Madrid.
The crewwoman didn't actually reach for the credit chips, of course. That sort of thing simply wasn't done. Besides, she knew as well as Hutchins did that if she'd been foolish enough to insert her hand into that box, the automatically descending lid would have removed it quite messily. Instead, she produced a small hand unit, aimed it in the direction of the chips, and studied the readout. She gazed at it for a moment, making certain that the amount on the readout matched the one Hutchins' superiors had agreed to, then nodded.
There is no need for a PIN with these things.

I was thinking much of the same in a question upstream about how one pays for things. It has to be as practical as paying with paper currencies. One of my cards can be used to debit my account by physically touching the card to a properly equipped register at checkout. RFCs post above seems to corroborate it as well.
I wonder how secure these things really are even in the HV. High tech cards only beget high tech criminals. If you notice in the above post, a device is used to scan the amount on the chips. They aren't SUPPOSED to be hackable. Yet, our current bank cards aren't supposed to be either.
I do not think there is a contradiction in saying no PIN is needed. Note that no PIN was entered to read the amounts; but that is the only thing that you are allowed to do with these chips, since the amount is fixed when issued by the bank. So the "security key" is just there as part of the anti-tamper protocol.
Clearly security protocols are better in the Honorverse, because Haven was not able to exactly duplicate technology even when they have a captured example of it.
Even paper money has a "security key" in the form of serial number, but clearly no PIN is needed.
