The Welsh Assembly has pledged £1.7m towards a new NHS website, which will allow patients to book their GP appointments online.
The My Health Online site will also allow people to order repeat prescriptions and check their medical records, Health Minister Edwina Hart said.
She added: "The demand for online GP services is increasing and we recognise that providing accessible information is critical if we want to enable people to change their lifestyles and improve their health.
"The Welsh Assembly Government is also committed to improving access to health services for people living in rural communities. My Health Online will particularly save lengthy journeys to GP practices.
"The website will also help empower people to take responsibility for their own health through the completion of a health diary which can be shared with their GP."
No start date for the website, which is still in its development stage, has been confirmed, but it could be up and running by the end of the year.
It is intended that all GP practices in Wales will take part so patients will use the same online service wherever they log on.
"I think it could help people who are unable to be on the phone trying to get an appointment for that day, between 8.15am and 9.30am whilst travelling to work. Trying to get through to north Cardiff medical centre can be exhausting at that time in the morning and can leave the patient feeling stressed before they have even spoken to receptionists. I can rarely get an appointment with the GP I would prefer to see. If the new system means I can book an appointment with the GP or nurse practitioner of my choice for planned routine consultations at a time that fits in with my work pattern, then I think this would be a vast improvement on the current system we are forced to tolerate. I also believe this will cut down on unnecessary negative discussion between some receptionists and patients. I welcome this change in practice and would be grateful for the proposed changes" - Lynda Smith, Cardiff
