Abstract
Method and system for coordinated management of a plurality of contactless radio-frequency readers of chips incorporating electronic microcircuits. The method includes transmitting, in a first time interval, transmit operations composed of command instructions from each of the plurality of readers to the electronic microcircuits of the chips associated with each respective reader; and receiving, in a second time interval, receive operations composed of responses from the electronic microcircuits of the chips associated with each respective reader. The first and second time intervals do not overlap.

A method for coordinated management of a plurality of contactless radio-frequency readers of chips incorporating electronic microcircuits, the method comprising:
- transmitting, in a first time interval, transmit operations composed of command instructions from each of the plurality of readers to the electronic microcircuits of the chips associated with each respective reader;
- and
- receiving, in a second time interval, receive operations composed of responses from the electronic microcircuits of the chips associated with each respective reader,
- wherein the first and second time intervals do not overlap.
A contactless radio-frequency reader of chips incorporating electronic microcircuits, comprising:
- a transmitter and receiver for respectively sending and receiving transmit/receive cycles for the electronic microcircuits;
- and
- a synchronization unit structured and arranged to synchronize the transmit/receive cycles with transmit/receive cycles of other readers associated with other electronic microcircuits.
A system of contactless radio-frequency read/write readers of chips incorporating electronic microcircuits, comprising:
- a plurality of readers;
- a synchronization circuit being coupled to the plurality of readers and adapted to implement a synchronization of transmit/receive cycles of the plurality of readers;
- and
- a microprocessor based central control unit structured and arranged to manage the synchronization circuit 46. A system of contactless radio-frequency read/write reader of chips incorporating electronic microcircuits, comprising:
- a plurality of readers;
- and
- a synchronization circuit structured and arranged to synchronize transmit/receive cycles of the readers and including a clock signal switching device for switching from an internal timebase to a timebase of a central processing unit.
