What is an Oyster Card?

The Oyster Card. What is it? What does an Oyster Card do? 

An Oyster Card is the size of a credit card. It’s a smartcard that is used to pay for trips on London Transport. This includes the tube network that dates from Victorian times and those cute red London buses. You can’t really say you’ve been to London without experiencing both of those!

Your Oyster Card can be topped up so it’s ready for use. This saves you time as opposed to buying separate tickets. It can also save you a lot of money. Some London Underground Oyster card fares, for instance, are less than half the price you’d pay for an individual ticket. That’s a considerable saving.

What does the Oyster Card cover?

The Oyster Card allows you to pay as you travel by London Transport.

This includes tubes, buses, the DLR, trams, most overground trains, the rapid transit Elizabeth Line, Thames Clipper boats and even the Emirates Air Line.

You can also use it to pay for train journeys between Gatwick airport and the city, or to take the tube between the city and Heathrow airport

If you haven’t been to the British capital before, one thing to know is that the city is divided into zones. Travel fares are then calculated accordingly. A Visitor Oyster Card can be used in all 9 zones, though many residents and tourists never stray far beyond the more central areas. 

A clever feature of the Oyster Card is that it will calculate the lowest available fare for each journey you make. 

Oyster cards can be used on London buses.

Types of Oyster Card

So when you’re asking what travelcard do I need, it’s a good idea to understand the kinds of Oyster Cards you can buy. 

There are two main types of Oyster Card in the UK. There’s the standard version that residents tend to use, or the Visitor Oyster Card. An Oyster Card for children also gives them a considerable discount on travel. 

Both the standard and visitor Oyster Card for London costs £5 to buy and activate. The key difference to be aware of is that a regular Oyster Card can be loaded with a London travelcard, and a visitor one cannot. You’ll also pay postage on a visitor card. 

If you’re staying a while, this could mean saving money. A 7-day travelcard, for example, can be great value for money if you’ll do a lot of travelling during a week’s stay. Here’s a quick reference guide to the key differences.

Children’s Oyster Card

If your child is aged 11 or less, then they don’t need to pay for travel when they’re with a fare-paying adult. Up to four under-11s per adult can travel for free on buses, tubes, trams, the  DLR, the Elizabeth line, London Overground services, and selected National Rail services. 

For kids over 11, TfL advises buying a Visitor Oyster Card. Once you arrive in London, a Young Visitor discount can be applied at a tube station, visitor centre or the National Rail ticket office at Victoria train station. This discount gives them 50% off the adult fare for up to a fortnight. 

The Oyster Card minimum balance

So what’s the minimum Oyster top up?

You can add any amount between £10 and £50, increasing in £5 increments. £10, £15, £20, £25, £30, £35, £40 or £50 can therefore be added to your card. This top-up never expires, so it’s good for future visits too.

Even TfL themselves suggest letting your friends and family use your Oyster Card for their trips to the capital too!

The Oyster Card maximum fare

One very interesting thing to know about the British Oyster Card is that your daily fares are capped. This cap limits the cost of every journey per day or week.

Once you reach a set limit – the cap – you will no longer be charged for any additional travel. Different price caps apply depending on whether you travel at peak or off-peak times. The caps that apply to bus and tram journeys versus other forms of London Transport also vary.

Transport for London says that capping is more cost-effective than a one-day travelcard when you make a few train trips per day. The same applies with the Oyster maximum fare when you use a combination of bus, tram and rail journeys during the day. 

Always touch in and out with your Oyster Card when making your journeys, otherwise you could be charged the full fare for that trip! You should also use the same card or device each time for the fare cap to be applied.

How to get an Oyster Card

There are three main options for those wondering how and where to buy an Oyster Card. You can order one online, get one as part of the London Pass or buy one in person.

Buying an Oyster Card online

If you want to buy an Oyster Card to be sent to an address outside the UK, you’ll need to get a Visitor Oyster Card. Standard cards can only be posted to a UK address. 

You can buy your standard or Visitor Oyster Card directly from TfL. 

Buying the London Pass and Oyster Card

Those who buy the London Pass can opt to add an Oyster Card to it. This is a pass for a duration of between one and seven days, increasing in daily increments. There is also a 10-day version.

The London Pass gives the holder access to over 80 London attractions, including Thames river cruises, London bike hire and hop-on hop-off bus routes. With key sights such as the Tower of London, Greenwich Observatory and London Zoo covered, it can be a very worthwhile purchase!

Buying an Oyster Card in person

The final option is to buy an Oyster Card when you arrive. You may only be able to obtain a standard one this way, however: the sale of visitor cards is limited. They’re sold only via certain tourist offices, overseas travel agencies, on board a London-bound Eurostar train and at some London airports.

You can buy standard Oyster Cards once you’re in the city from tube station ticket machines, train stations, London Transport Visitor Centres and Oyster ticket stops.

Top-ups can be purchased at the same places. 

How to use the London Oyster card

You need to use your Oyster Card at the beginning and end of each journey unless it’s made on a tram or bus. Otherwise, London Transport cannot calculate the correct fare to charge to your card. 

There are yellow card readers to use for this purpose. Don’t touch out when you alight from a bus or tram. For tubes, trains and other forms of transport, it’s important to use the same card or device each time.

If there are no gates – or these are open – you still need to touch in or out on a yellow card reader at the station.

We love the Oyster Card maximum daily fare feature when visiting London. Using the card also saved us time as well as money while exploring London.
