An RF-UCard system is a contactless smartcard syste m with multiple chip operating systems and multiple applications. A multi-card collision occurs when mo re than one card within the reader’s read field and thus lowers the efficiency of the system. This paper pre sents a novel and enhanced algorithm to solve the multi-card collision problems in an RF-UCard system . The algorithm was originally inspired from framed ALOHA-based anti-collision algorithms applied in RF ID systems. To maximize the… Expand

ALOHA packet system with and without slots and capture
Roberts investigates methods of increasing the effective channel capacity of such a channel and proposes to consider the channel to be slotted into segments of time whose duration is equal to the packet transmission time, and to require the devices to begin a packet transmission at the beginning of a time slot.
