Systems and methods allow for the integrated circuit cards (ICCs) to removably couple to each other and transmit information to an access device as a single device. One among the two or more ICCs coupled together may read data from the remaining ICCs and provide the data to an access device via contactless communication. The ICC may include a substrate; an integrated circuit embedded in the substrate; input ports exposed on a first surface of the substrate, and output ports exposed on a second surface of the substrate. The input ports and the output ports are electrically coupled to the integrated circuit. The output ports are configured to be removably coupled to the input ports of a second ICC.

A computer-implemented method of operating a payment card network is proposed in which the expiry date of each payment card is stored, not on or in the payment cards themselves, but as a payment card record within an electronic database. When the payment card is used, the record is accessed using other payment card details to check that expiry date has not passed. The process does not require that the expiry date is read from the payment card. This has the advantage that the payment card does not have to be replaced at the expiry date. Instead, the expiry date can be updated by updating the record. In place of the expiry date, the card has an auxiliary date which is the birthdate of the consumer in the YYMM format.

The present disclosure is related to a field of payment transactions using a card that discloses a computer-implemented method and a system for restricting a transaction while using a payment card. A card processing server may receive card details, a transaction amount, a flag, and signature data of the payment card from a remote terminal upon initiating a transaction using the payment card. Further, the card processing server validates the payment card based on the card details and the signature data of the payment card and thereafter determines a value associated with the flag upon successful validation. The value associated with the flag indicates one of two conditions, e.g., a true condition and a false condition. Based on the condition indicated by the flag, the card processing server performs one of a first action and a second action related to either processing or declining the transaction.

Methods, apparatus and computer software are provided for authorizing an EMV transaction between a user device and a point of sale terminal, particularly, but not exclusively, in situations where a secure element is not made available for the deployment of a payment application on the user device. The payment application is instead deployed to a processing environment that is outside of any secure element on the user device. An ICC Master Key corresponding to the payment application is held by a trusted authority, such as the issuing bank. The trusted authority is adapted generate time-limited session keys on the basis of the ICC Master Key and distribute session keys to the payment application. Receipt of a session key by the payment application enables the payment application to conduct an EMV payment transaction. The session key is used to authorize a single EMV payment transaction.

Various embodiments are generally directed to enhancing a card activation experience for an authorized card user when activating a new card by at least displaying various types of information related to the new card in augmented reality (AR) and allowing the user to perform the activation itself or experience other aspects of the activation process in AR. Information pertaining the successful activation of the card may also be provided to the user in AR.

Example embodiments of systems and methods for data transmission system between transmitting and receiving devices are provided. In an embodiment, each of the transmitting and receiving devices can contain a master key. The transmitting device can generate a diversified key using the master key, protect a counter value and encrypt data prior to transmitting to the receiving device, which can generate the diversified key based on the master key and can decrypt the data and validate the protected counter value using the diversified key.
