My uKoo ("uku", Hawaiian for Gift or Reward) is a QR Code/NFC application for a Digital Loyalty Rewards Card.
You can't get any closer to an actual Punch Card than this.
Look for the My uKoo logo at your favorite store. Download the App and Scan the QR Code or Tap the NFC Tag to register and get your first Credit.
Each Scan of the QR Code or Tap on the paired NFC Tag earns 1 credit. Once the "FREE" item is redeemed, the card clears to start over.
