Yes, I am saying that. Who made the bad cards? CPI made the card that works for me, G&D the cards that didn't.
Where can I see who issued the cards ? Interesting ....I would like to check if the blue and the two others that are not working were issued issued from a different company.... but I cannot find anything on the cards
They're all ISSUED by Discover. But if you look at the top right on the back you can see the manufacturer. For CPI it will say "cpi-co", for Giesecke & Devrient (G&D) it will have a tiny version of their logo.
Thanks a lot.. now I see it. For me all the cards issued by G&D are not working. CPI reads chip smoothly ...wow... strange that Discover has not all cards issued by the same company.
Same here, though one person on another board has an issue with a CPI card. Still, it seems that the CPI cards at least work sometimes, I have not yet seen one report of one of the G&D cards actually working.
It's no surprise at all to use multiple vendors. It allows orders to be spread out, and gets companies to compete against each other. CPI and G&D are both major, reputable smart card vendors. I would not blame G&D for this problem. It is more likely a problem in Discover's customisation of the cards, but we just... don't know. Nor do we know how they'll fix it. Depending on how far they're ACTUALLY getting, it may be possible to fix these cards remotely by issuer script (though I doubt it).
It could also be that the cards are fine and it's an issue in the D-PAS application and certification, though this seems much less likely. It's also possible an update to D-PAS could enable them to work. Still, doubtful. I suspect a re-issue of these cards is in the not-too-distant future...
Great info. At least I learnt something now... I looked at my cards and could not tell the difference but with your explanation I can see the G&D logo 
... at the moment I am amused when merchants keep telling me ..." no no... you cannot wipe this card! It has a chip " ... shocked sales personal in Europe that had also the impression a chip card cannot be swiped ... Discover shows otherwise ..lol... I just checked and the garnet red is CPI as well and I know I had that one used with chip before.

So, there are two issues here:
1. The G&D cards seem to have some issue. Probably Discover's personalisation is failing, yet somehow validating, but that's pure speculation on my part.
2. Many merchants, even chip-enabled ones are not enabled for chip DISCOVER/DINER'S (D-PAS). At these merchants, still insert the card first but then swipe it when the terminal errors or says to swipe the card.
@lg8302ch wrote:I am looking forward to the little experiment now. Whenever a merchant terminal requires to swipe the D&G card I will simply select a CPI card and insert the chip again. If this processes by chip then I know it is the card and the merchant has chip enabled for Diners. Curious to see the result. I am almost positive that DCI cards will process because I am sure I would have noticed if the card had required swipe after inserting chip in the past... it is so unusual and since I do not remember such actions I am pretty sure it worked with the garnet red in the past.
Update on my little experiment. It is indeed the Discover chip cards issued by D&G (New York and Daisy Gerbera designs) that will not work with chip. When the terminal was requesting to swipe I cancelled and tried the Discover card issued by DCI and yes smooth processing with chip. Tests at the same merchant which has chip enabled for at least 10 years but Discover cards from D&G get refused. Swipe only. But the ones from CPI (blue and garnet red) get processed by reading the chip smoothly. It looks that the D&G cards are not compatible to chip readers 
Just upgraded my card to CHIP version. Will see how it goes. Have been using CHIP cards with CHASE, Barclay for quite long. No problem while swiping the magnetic strip of those cards. Plus lots of merchents already started using CHIP card terminals.
