The card surcharge ban started in Australia today, 1 October. Shops can no longer add a fee when you tap your card. The Reserve Bank of Australia says shoppers at businesses that used to surcharge will pay similar amounts to before. The fee stays. It moves from the bottom of the receipt into the price on the shelf.

Read that again, because the regulator has put the whole story in its own summary. The surcharge was the visible part of a bank fee. We banned the visible part. The fee kept its job.

My take on this? The small business owner has been cast as the villain of this story. The owner was the messenger. Everyone in the chain has a business to run, and the customer pays for all of it, as the customer always has.

We banned the receipt line. The fee stayed.

What changed on 1 October

Every time you tap a card, the shop pays a fee to process the payment. The fee goes to the shop's payment provider, which is the bank or company that runs its card machine. Part of it flows on to the card network, such as Visa, and part of it to the bank that issued your card.

Until yesterday, a shop could recover that cost with a surcharge: a small percentage added to your bill when you paid by card. About 16% of Australian businesses surcharged, according to the RBA. Australians paid about $1.6 billion a year in those fees.

From today, surcharges on Visa, Mastercard and eftpos cards are banned. American Express and UnionPay are removing their surcharges too, and PayPal follows from 5 October, Bloomberg reported this week.

The RBA's case is transparency. The price you see on the shelf becomes the price you pay at the till. Surcharging was allowed more than two decades ago to steer shoppers toward low-cost ways to pay. Cash now makes up only about 15% of Australian transactions, so that job is mostly done. The UK and the European Economic Area already ban surcharges on most consumer cards.

Here is the part the headlines skip. The ban stops the shop charging you the fee. Banks, card networks and payment providers still charge the shop, every single tap.

Meet the villain, on a 2.6% margin

The public story has a clear bad guy. The shop owner who adds 1.9% to your flat white. Caught, stopped, justice served. Everyone can go home.

Here is the business that villain is running. Restaurant & Catering Australia, which represents 57,000 eateries and caterers, says the average restaurant made a net profit of 2.6% last year. On a $100 bill, that is $2.60 left after wages, rent, stock and fees.

Now take the card fee away from the customer and hand it back to the owner. In its 2024 review, the RBA looked at what small merchants pay. The largest group paid average merchant service fees of 1.5% to 2% of each sale. Some paid well over 2%.

A retail analyst at MST Financial set out the maths this week. A shop on a 5% margin that absorbs one extra percentage point loses 20% of its earnings. A cafe on a 2.6% margin has even less room to absorb the same point.

So the owner has two choices. Reason one to raise prices: absorbing the fee eats the profit. Reason two: there is nothing else left to cut. One Melbourne cafe told Bloomberg it will add 50 cents to a coffee and $1 to a panini. It said the rise only covers the surcharge it just lost.

The surcharge was a cost. The ban removed its label.

Who owns the fee

Every tap sets off a chain. Your bank issued the card. Visa, Mastercard or eftpos run the network in the middle. The shop's payment provider runs the machine on the counter. Each one takes a cut, and the shop pays the lot.

Everyone in that chain has a business to run, and that is fair. Banks fund fraud checks, rewards points and a network that clears payments around the clock. The fee is how they pay for it. The cafe has a business to run too. Until yesterday it recovered its costs the same way the banks do: it charged the customer.

The difference is size. The RBA found small merchants pay around three times the per-transaction fee that large merchants pay. Supermarkets negotiate their rates. The corner cafe takes the rate it is given. Surcharging was already rare among large chains, so for them, today is an ordinary Thursday.

The banks are giving something up. At the consultation stage, the RBA estimated its reforms would cost domestic card issuers $880 million on a net basis, Banking Day reported. The main tool is a cut to interchange fees. From today, the cap on domestic consumer credit cards falls to 0.3%. The RBA says small businesses should receive the bigger reduction.

Here is the catch. The interchange cut lands with the shop's payment provider first. The Australian Retail Council says the benefit depends on how much providers pass through to shops. The RBA will make the large providers publish their fees, so owners can compare. Doing the comparing is the owner's job.

So who pays? You do. You always did.

The RBA's own summary says customers at businesses that used to surcharge will pay similar amounts to now. The money arrives through the shelf price instead of the surcharge. That is the regulator stating, in writing, that the bill lands in the same place.

What changes is who shares it. Under a surcharge, the person tapping the card paid the card cost. Once the cost sits in the price, everyone pays it. That includes the person handing over a $20 note.

Cash customers are a small group, at about 15% of transactions. They are also the one group whose bill just rose for a service they did not use. The Independent Payments Forum is a coalition of small business groups. It warned the RBA that a ban would lift prices for all consumers, including those who use cash.

Here is my prediction, labelled as one. Prices at small businesses that surcharged will rise by about what the surcharge used to be, less whatever the interchange cut hands back. The RBA's fee data puts that at 1.5% to 2% for most small merchants. We will feel good about it anyway, because the line on the receipt is gone.

Congratulations to us all. We removed the fee we could see and kept the one we could not.

How this hits your business

Get your real card cost in writing. Ask your payment provider for your total card fees and your total card sales for the last three months. Divide one by the other and you have your true rate. The interchange cut applies from today. If the rate is unchanged on your next statement, ask your provider why, and compare it against the fees the large providers must now publish.

Raise prices once, and say why. If you need to lift prices, do it in one round, across the whole menu, on one date. Put a short note at the counter saying card fees are now included in the price. It is honest, and it tells customers where the change came from.

Switch on least-cost routing. Least-cost routing sends each debit card payment through the network with the lowest fee, usually eftpos. The RBA's figures show eftpos is generally the least expensive network for merchants. A NSW Small Business Commission survey in 2021 found one in two small businesses taking cards had never heard of it. Ask your provider whether yours is on. For a business with lots of debit payments, it cuts the fee and your prices stay put.

The fee has an owner. Ask for its name.
