Visitors to the Oyster Online page on the Transport for London website will now be presented with a direct link to join the NHS Organ Donor Register.
According to the Cabinet Office, which, along with London Mayor Boris Johnson, is behind the scheme, three people die every day because of a lack of registered organ donors.
The majority of new people signing up to the Organ Donor Register comes through the Driver and Vehicle Licensing Agency (DVLA). However, Department of Transport statistics show that London is the area with the lowest car ownership rate in the UK. It's thought that the TfL website will reach a large number of people living in the Capital.

The family of Carina Marcangelo say she is in a critical condition following surgery on Sunday but making steady progress.
Carina had a disease which damages the heart and became the youngest person in Britain to be fitted with a mini-defibrillator.
Carina has cardiomyopathy which damages the heart. She spent her first birthday completely sedated on life support at the Royal Brompton as she awaited a donor organ.
She became the youngest child to be fitted with a mini defibrillator (ICD) in her chest in November at just 9 months old. The device gave her heart a shock if its rhythm worsened.
Carina could only receive a heart from a one-year-old to a small five-year-old. The average waiting time for a heart is around 3 months.

In London and its surrounding regions, there are 4.3million people on the list but, they are always in need of more to increase the chances of helping the 2,000 patients waiting for a transplant.
Whilst great work is being done and live are being saved, there are still people dying. Last year from April to January, 864 patients got the organ they needed. Sadly it was not enough for some and over 60 people died whilst waiting.
