Title (EN) COMMUNICATION PROTOCOL SPEEDUP AND STEP-DOWN
(FR) ACCÉLÉRATION ET ABAISSEMENT ASSOCIÉS À UN PROTOCOLE DE COMMUNICATION
Abstract:
(EN) A payment terminal such as a payment reader may receive and form electrical connections with an electronic transaction card such as an EMV chip card. The payment terminal may provide a clock signal at a rate that exceeds a specified rate for the EMV chip card. The payment terminal may transmit messages to the EMV chip card and monitor receive messages at a data connection. The payment terminal may determine that the clock rate is excessive based on a timeout of a receive message, an error rate of a receive message, or a receive message indicating that one of the transmit messages was not received by the EMV card. The payment terminal may reduce the clock rate to a rate that is below the specified rate for the EMV chip card.
(FR) L’invention concerne un terminal de paiement tel qu'un lecteur de paiement pouvant recevoir et former des connexions électriques avec une carte de transaction électronique telle qu'une carte à puce EMV. Le terminal de paiement peut fournir un signal d'horloge à une fréquence supérieure à une fréquence spécifiée pour la carte à puce EMV. Le terminal de paiement peut transmettre des messages à la carte à puce EMV et surveiller des messages de réception au niveau d'une connexion de données. Le terminal de paiement peut déterminer que la fréquence d'horloge est excessive sur la base d'une temporisation d'un message de réception, d'un taux d'erreur d'un message de réception ou d'un message de réception indiquant qu'un des messages de transmission n'a pas été reçu par la carte EMV. Le terminal de paiement peut réduire la fréquence d'horloge à une fréquence qui est inférieure à la fréquence spécifiée pour la carte à puce EMV.
