Card Surcharge

A card surcharge is a fee a business adds at the till for paying by card, usually shown as a percentage like 1.5%. It exists because merchants pay their bank a fee to accept each card type, and Reserve Bank rules let them pass that cost on instead of absorbing it. Debit eftpos typically costs the merchant well under half a percent. Scheme debit sits a bit higher, and credit costs more again. That gap is why tapping your phone often triggers the credit rate even when the money comes from your own bank account.

The legal line is cost of acceptance. Since the RBA's ban on excessive surcharging, enforced by the ACCC, a merchant may only charge what it actually costs them to accept that card, and the ACCC can require proof. A flat 2% on everything, applied to debit cards whose real cost is a third of that, is precisely the pattern the ban targets.

For the worker tapping through their pay cycle, the surcharge is small per transaction and genuinely meaningful across a year of coffees, lunches and petrol, which is the sort of arithmetic this site exists to make visible.

The merchant's bank sends a monthly statement listing what each card network actually charged: eftpos, Visa debit, Mastercard credit and the rest, each with its own percentage. The RBA standard says any surcharge can be no more than the cost shown there for that payment type. A merchant choosing one blended rate must pitch it at or below the cheapest card they accept, which is why compliant signs often read 1% for credit rather than a single number for everything.

The routing detail is where your money quietly leaks. Every tap defaults to the credit or scheme-debit rails, whose acceptance costs run roughly double to triple the eftpos rails an inserted debit card uses. Dual-network debit cards let the merchant, or you, choose eftpos at the terminal, and many terminals now do least-cost routing automatically. The tap-to-credit path is exactly why your phone payment at the servo attracts 1.5% while the person in front inserting their debit card paid nothing extra.

Enforcement is the ACCC's job. Merchants must disclose the surcharge before you pay, must not exceed cost, and can be fined for systematic overcharging. As the payer, your counter-move is mechanical: insert and choose eftpos for anything over about twenty dollars, treat flat minimum-purchase surcharges with suspicion, and keep the petty spending honest with a budget planner so a year of invisible percentages shows up as one visible number.

Surcharges are a per-transaction tax on convenience, and convenience is precisely the spending mode most likely to run unexamined. Nothing about 75 cents on a lunch feels decision-worthy, which is what makes the category worth pricing annually. A worker tapping a card for $150 a week at 1.5% pays roughly $117 a year in surcharges, enough to matter and small enough to never be noticed, which describes most leaks in a household budget.

A colleague named Brent (yes, that Brent) once argued with a cafe over a 2.2% flat surcharge applied to every card type including eftpos debit. He was, for the first and possibly only time in recorded history, correct about a financial regulation. The ACCC's excessive-surcharging ban exists because that exact sign was once standard practice, and the cafe's 2.2% on a debit transaction costing them perhaps 0.3% was textbook excessive. Brent collected no refund, but he did collect a reputation at that cafe, which he wears as a sash.

The highest-leverage habit takes one afternoon: check your bank app for how your tap routes, insert the card and select eftpos on larger purchases, and sense-check the annual drag with the pay frequency tool if your spending syncs to payday. If a merchant's percentage smells wrong, the ACCC takes the complaint, not you personally at the register with a queue behind you.
