[Star Wars] How did Qui-Gon Jinn "send" a blood sample to Obi-Wan and why does a royal vessel have a midichlorian counter on board?

Jedi probably carry a device to test potential force users with them at all times, you know, for recuitment.

Qui Gon's device sent Anakin's blood makeup wirelessly to Obi's device, who in turn plugged it into the Ship's computer for the extra processing power.

With the extra power, it could also count the number of midichlorwhatnots, instead of just reading his blood makeup.
