PerkWallet is a mobile-based service operated by Unified Select Pty Ltd, a company based in Sydney, Australia. It gives people one place to keep perks from participating shops, companies, brands and events, using a mobile number instead of a physical card or separate account. The service is free to use, requires no advance sign-up, and automatically creates a wallet when someone collects their first perk.

PerkWallet supports multiple stamp cards, free gifts, Perk Points and prize-draw entries. Customers can collect a perk by scanning a QR code or receiving it directly on their number, then access their wallet online at my.perkwallet.com. Each perk includes information about where it can be redeemed. At the venue, customers tap Redeem and identify themselves by name or nickname; a four-digit verification code is also provided.

For participating shops, PerkWallet offers a way to welcome customers who arrive with a perk to redeem. The company says businesses pay for what customers collect and that participation costs them nothing.
