Dynamics' Chip & Choice™ technology includes two chips - a secure, embedded chip and an exposed chip. A user can select different payment options by pressing different buttons on the card. Dynamics' secure, embedded chip then writes a different, temporary chip profile into the exposed chip based on the user's selection. In doing so, a user can select and use different payment applications even with readers that do not support such applications. This level of flexibility, unique to Dynamics payments cards, negates the needs for costly infrastructure updates in order to deliver powerful new functionality to merchants, networks, card issuers and consumers.
