Support of Card Technologies
Three different Card Data Sources (or card technologies) have
been defined:
• ICC,
• Magnetic Stripe (Track 2) and
• Key–Entered
Presently, Key–Entry of card data is not supported.
A terminal able to accept Debit/Credit cards shall accept both
ICC and Magnetic Stripe (including fallback from ICC) as card
data source.

7.7
ICC Technology and Fallback to Magnetic Stripe
When an ICC is inserted into the ICC reader, the terminal shall
try to communicate with the ICC. This communication may
fail, and fallback from ICC to Magnetic Stripe may be the only
way to continue and complete the transaction.
If the terminal is attended and the terminal has separate ICC and
Magnetic stripe readers, the merchant shall be able to testify that
the ICC has been inserted correctly, before fallback to magnetic
stripe may continue.
To be able to testify correct card entry, the Merchant Interface
shall include two keys/menu items (“Yes”/“No”) to activate
when the question “Card inserted correctly?” appears.
If the magnetic stripe is used and the magnetic stripe indicates
that the card contains an IC, the terminal will reject the attempt
and request the cardholder to use the ICC reader instead.
