1. A system for transferring data from a portable data capturing device to a data processing means, the system comprising:
- a wireless communications means for transmitting data from said data capturing device to the data processing means, the wireless communications means comprising a transmitter in communication with said data capturing device and a receiver in communication with the data processing means, the transmitter having a finite transmission range; and
a buffer in communication with said data capturing device for temporarily storing at least some of the data captured by the said data capturing device, wherein data which is temporarily stored in the buffer is only transmitted to the receiver when the receiver is located within the transmission range of the transmitter, and when a force sensing means provided in the data capturing device senses that contact between the data capturing device and a surface has been broken.

Abstract
A system comprising: a wireless communications system for transmitting data from a data capturing device to a data processing device. The wireless communications system has a transmitter in communication with the data capturing device and a receiver in communication with the data processing device. The transmitter has a finite transmission range. The system also includes a buffer in communication with the data capturing device for temporarily storing at least some of the captured data which is only transmitted to the receiver when the receiver is located within the transmission range of the transmitter.
