Wearable devices having multiple distributed radio frequency identification antennas

A wearable device comprising:

• a battery module;
• an RFID radio;
• a first RFID antenna;
• a second RFID antenna;
• an electronics module including a processor, wherein the processor is configured to select for activation one of the first RFID antenna or the second RFID antenna based upon at least one of a location or a type of an RFID object external to the wearable device;
• and
• a body, wherein, when the wearable device is worn, the battery module, the RFID radio and the electronics module are stacked and disposed at one or more fingers of a user's hand, the first RFID antenna is disposed at an upper side of the user's hand, and the second RFID antenna is disposed at a user's wrist,
• wherein the processor is further configured to, when a movement of the wearable device is detected, switch from the first RFID antenna to the second RFID antenna to read the RFID object.

A wearable device, the wearable device comprising:

• a first radio frequency (RF) antenna;
• a second RF antenna;
• a processor configured to select for activation one of the first RF antenna or the second RF antenna based upon at least one of a location or a type of an RF object external to the wearable device;
• and
• a body, wherein a radio, the first RF antenna, and the second RF antenna are disposed at respective positions along the body,
• wherein the processor is coupled to the radio via a wireless transmission protocol.
