The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section. A summary of the conclusions reached follows.
The result was merge PINsentry into Chip Authentication Program. -- Jjasi (talk) 07:06, 18 August 2008 (UTC)

  • Vote for. The PINsentry page seems unnecessary given the detail here. Jjasi (talk) 13:15, 10 July 2008 (UTC)
  • Agree. PINsentry describes the exact same thing, but is a much less well informed stub. PINsentry is just the marketing name of one single UK bank for the Chip Authentication Program. Their readers are exactly the same as the many other CAP readers that lots of banks are rolling out at the moment. They are fully compatible and interchangeable. No need to have a separate article for each bank's marketing term for the exact same technology. Markus Kuhn (talk) 13:20, 10 July 2008 (UTC)
  • Support merger - no need for separate article for Barclays. TalkIslander 13:34, 10 July 2008 (UTC)
  • Disagree The PINsentry system has specific details that would be lost in any merger Little Professor (talk) 12:01, 27 July 2008 (UTC)
    • Such as? Any specific differences between systems can easily be mentioned in this article, but it still doesn't warrent it's own article. TalkIslander 12:35, 27 July 2008 (UTC)
  • Agree. PINsentry is just Barclay's branded implementation of CAP. —Preceding unsigned comment added by (talk) 14:43, 30 July 2008 (UTC)
4 say merge, 1 says not. If nobody objects within the next 48 hours I'll summarise the merge proposal as a vote to merge. Jjasi (talk) 19:38, 15 August 2008 (UTC)

Merge done. Didn't copy anything across from the old article as it didn't seem to add anything to that already here. Jjasi (talk) 08:49, 18 August 2008 (UTC)

Wrong page name?[edit]

Isn't that "Chip Authentication Protocol" instead of "Chip Authentication Program"? For example, I found this page which talks about Chip Authentication Protocol. Should we rename that page?

NatWest also uses this and it seems their card reader is compatible with Nationwide's. —Preceding unsigned comment added by Yanson (talkcontribs) 16:19, 5 January 2009 (UTC)

It's also compatible with Barclays'. (talk) 01:54, 5 February 2009 (UTC)
I believe any reader can be used to read any card. (Regardless of who supplied the card/reader.) —Preceding unsigned comment added by (talk) 21:28, 14 December 2009 (UTC)
yes, APACS consortia members decided to create a standard hardware specification for the reader so that any UK card could be used with any branded reader. The NatWest/RBS reader (manufactured by Xiring), e.g. the RBS/NatWest branded readers have the Identify and Sign buttons that are not used by the bank.

Academic paper describing UK CAP protocol[edit]

I am a co-author of an academic paper (published at Financial Cryptography 2009), describing the operation of the UK CAP variant. Contributors to the article may wish to incorporate some of the information it offers. SJMurdoch (talk) 13:34, 26 February 2009 (UTC)

- Done, as of 2009-06-30. - quixoticgeek —Preceding undated comment added 23:57, 29 June 2009 (UTC).

"Incompatibility" section[edit]

The "Incompatilility" section states that "CAP readers are generally not compatible with cards from differing issuing banks."

This is rubbish. You can use a card issued by any UK bank in any UK bank's card reader. They are all compatible. (talk) —Preceding undated comment added 23:22, 31 October 2011 (UTC).

How are changed PIN numbers sent to card readers?[edit]
