Without the module, images from the 500SE are just points on a map without an indication of which direction the camera is facing.
Ricoh also has two models of the Caplio 500SE, a model W and a model B. You can transfer photo data to PCs and other devices supporting Bluetooth and/or wireless LAN with both models.
You can also connect the Caplio 500SE wirelessly with a Bluetooth compatible GPS device to add location information to your photo data.
The cameras also have an antiblur function and a flash range of 10 meters.
