Hey @Cosmic10,
I noticed it's your first post, welcome to our community ๐
You can accept any Australian-issued and most international chip cards or magstripe cards with a Visa, Mastercard, American Express, and JCB logo. Square also supports mobile wallets such as Apple Pay, Google Pay, and Samsung Pay, and bank-issued eftpos chip cards. If you're seeing a card declining, it's a good idea for your customer to check that they have sufficient funds in their bank account, or contact their bank directly to see why their payments are getting declined.
