When you use your HyperJar card for travel, such as with TFL, you may notice a charge of around 10p. This is called an authorisation charge, and this is how the travel companies check that your card is valid before taking the full amount of the fare. Most companies process this within 24 hours, however they do have up to 14 days to take the full fare from your account.
