I bought two VeriShield file signing cards. Unfortunately neither of the cards work--they each give a "wrong pin" error.
PIN Entry Try is 3. Do we see any message if the cards are locked? Can we sign the file as default and download the app to terminal? Also will there be any ownership issues if I sign the files as default for development?
Let's start with why you are getting the wrong PIN. There could be a few different reasons:
VERIFY YOU HAVE THE RIGHT PIN
When you first got your cards, each one should have come with a welcome letter telling you what the PIN is for that card. Note that each card will have a unique PIN and that you can't mix the two up (that is--if you try to enter the PIN for card 1 on card 2, it won't work and visa-versa).
NOTE: VeriFone is not infallible--when I was in my VF training class, one student got a pair of cards that didn't work and the teacher decided he must have had the wrong PINs sent to him. The only remedy is to contact the VF rep from whom you purchased the cards.
CHECK FOR PROPER INSTALLATION
If you are still having trouble, contact your VF rep.
I know that you do have a very limited number of retries before the card locks itself, but seeing as mine worked on my first try, I really couldn't tell you what happens as you approach and/or cross that limit.
That depends on what type of terminal you are using. If it is a Verix or VerixV (so like 3740, 3750, 3730, 510, 570) then, yes you can use a default signature (that's what I regularly do on these terminals) and no, it won't cause any problems, assuming everything else that is running on that terminal is also default-signed. If you are using some things that ARE secure-signed, then I believe that all items must have the same sponsor to run on that terminal (I know that's true with the eVo platform, but I'm just assuming on the Verix/VerixV platforms).
HOWEVER, if you are running an eVo terminal (like 520) then you MUST use a secure signature--eVo will not accept a default certificate. What's more, once a secure-signed program is loaded into the terminal, then ALL future applications MUST be signed using a certificate with the same sponsor, or that program will not run. (One exception--if you run the certificate removal program, then AFTER it runs, you can load a new sponsor on. However, note that the removal tool will not run unless it has been singed by the same sponsor).
Trying to use a default certificate should not cause any ownership problems, it just won't run. I know that if I try and use the default certificate on my terminal that already has a sponsor, it will compare the file signatures after download and say they don't match. I haven't tried it on a blank (no sponsor cert yet) eVo, but I suspect you would get roughly the same result.
Those file signing cards have gotten expensive recently, so if yours aren't working, then I'd get with the VF rep quickly and try to get it fixed--the longer you wait, the less likely they'll help you.
