The smallest, lightest timing system. With TSPortable you can time races in places that are inaccessible by vehicle, even in places where there is no mobile coverage. The TSPortable timing system is made up of an RFID mobile scanner, a mobile phone and the TSPortable app. Set up a timing point wherever you want and get your readings in real-time, all you need is an internet connection. Without a connection, the readings stored on your mobile device will send automatically when internet access is retrieved.
