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.
