A device implementing a scalable wireless transaction system includes at least one processor configured to receive, from a wireless transaction system server, a list of wireless transaction group identifiers, and an indication of at least one applet associated with each of the wireless transaction group identifiers. The at least one processor is further configured to receive, from a wireless transaction device, a polling frame that includes one of the wireless transaction device group identifiers. The at least one processor is further configured to select an applet provisioned on a device secure element that is assigned to the wireless transaction group identifier, the assigning being based at least in part on the received list. The at least one processor is further configured to utilize the selected applet to perform a wireless transaction with the wireless transaction device.
