A cash bail means the arrested person or someone on their behalf must pay the bail in full to the court.

A bail bond means going through a private bail company that will charge a fee between 10-15% of the original bail amount.
A property bond means using a piece of property as collateral (serving as an asset one pledges and can be taken if they fail to meet the terms of bail).
