Tesco plans to sell off-the-shelf insurance policies with no form filling after the success of its instant travel product.
The supermarket already sells home, pet and motor policies.
Its instant travel product uses information held on the store's loyalty card database to offer insurance free from forms or phone calls.
It sells about 180,000 travel policies a year, including the off-the-peg product.
Paul Baxter, the operation's head of insurance, said: "It's revolutionising the way insurance is sold.
"Motor is too complicated to sell in the same way but there are other products we might be looking at in the next few months."
The instant travel product was piloted in 2000 and launched fully late last year.
The store grew its book by 100,000 motor policies in the three months to the end of July. It promotes insurance in its 340 petrol stations.
The supermarket's personal finance arm - a joint venture with the Royal Bank of Scotland that sells home, motor, travel and pet cover - contributed £17m to Tesco's coffers in the 24 weeks to 10 August.
It has 600,000 in-force motor policies, 100,000 in-force home policies and 75,000 in-force pet policies.
One in three UK households already has a Tesco Clubcard .
