Abstract
Aspects disclosed herein relate to improving technology detection and collision resolution among multiple NFC devices using a NFC type-A RF technology. In one example, a communications device is equipped to determine that a first device sensing response message includes one or more collisions, identify a first remote NFC device of the plurality of remote NFC devices by performing collision resolution on the first device sensing response message, transmit a sleep request message to the first remote NFC device that prohibits the first remote NFC device from responding to a first device sensing request message and the first device sensing request message, receive a second device sensing response message that includes collisions among the plurality of remote NFC devices, and identify a second remote NFC device of the plurality of remote NFC devices by performing collision resolution on the second device sensing response message.
