| 摘要 |
The invention is an improved transaction verification method comprising a document, card or electronic apparatus with a transparent optical pattern visible to the user on a transparent window display. The verification process is performed by a user aligning the transparent pattern over a synchronized pattern image. The optical combination of these patterns induces a visual code, to be apparent to the user, which is then manually entered into a remote terminal or directly to the electronic apparatus to verify the transaction.
