The Telethought peek is included in the wallet, but it is not used by Dee Christopher. The technology for that specific peek is the same. This was thrown in as a bonus for completeness.
The style of the wallet and a couple of other design elements are very different from the Telethought wallet. The main difference being that the Razor wallet is clearly an everyday wallet where the Telethought wallet is meant to just hold business cards.
Other differences include the ability for the Razor wallet to be examined to some extent. The peeked at card is placed in between 2 credit cards. And, the addition of Dee Christopher's routines.
