ePal, which is partly owned by Australia's big four banks, announced its plans to implement a new interchange pricing structure in March. ZDNet report the new structure would have merchants charged an extra 5 cents for every transaction over $15 (paid to the party collecting the money), with an additions 1 cent going to ePal.
Trying to eliminate minimum spend limits in store, ePal decided not to charge any fees for transactions below $15. Also, supermarkets Coles and Woolworths would be exempt from the interchange fees due to a pre-existing parent relationship with ePal.
German Supermarket Aldi decided to take ePal to court over the matter, accusing it of revenue-raising, with the case filed on the 8th of September.
"With over five million EFTPOS transactions per day across Australia, it is possible that these new fees levied on retailers and merchants could lead to the banking industry reaping substantial additional revenue each year," the supermarket said in a statement.
Tom Daunt, Aldi's Managing Director, said Aldi did support the new interchange pricing model but was troubled by the lack of transparency around the new additional costs.
