To date, the only such supported dual application card is Card Type ‘07’, supporting ISO 14443
Type A, Mifare.
For normal ViVOpay transactions (those not in Pass-Through Mode), these cards are
automatically handled as ISO 14443 applications.
In Pass-Through Mode, the POS controls the polling mechanism. The POS can use a standard
, where Card Type ‘07’ establishes a Mifare session.
Alternatively, the POS can issue an
Enhanced Poll for Token
(02-0C), where Card Type ‘07’ can
establish an ISO 14443 session.
