Bicycle inflation systems are compact solutions for re-inflating your tire post flat. CO2 systems utilize a CO2 cartridge that is punctured to provide a quick burst of gas. It may not fully inflate your tire but will be enough to get you home. CO2 systems are the most compact and easy to transport but only give you one shot. Mini-pumps can be frame mounted and some are small enough to fit your seat bag. They will require more time to inflate a tire due to their low air volume but are easy to use and won't let you down. Hybrid systems have both a mini-pump and the ability to use a CO2 cartridge.
