MeT Example

Whilst shopping around for a new television set, the user finds a good price from a store and decides to order immediately. The store requests a ‘signed text’ confirmation from the customer:

As with many online transactions, the user enters all the details and must then press OK to confirm the transaction.

The user is requested to sign the transaction using a suitable certificate.

The certificate has a related signature PIN. The user enters the PIN to confirm the transaction.
