Running a loyalty program shouldn’t mean opening the door to fraud. Loyalty is a strategic engine that drives repeat visits, deepens guest relationships, and turns data into dollars. But that same engine is a target. Loyalty accounts are attacked 4–5x more often than ordinary accounts, according to Forter, and the stakes go well beyond stolen points: IBM’s 2025 Cost of a Data Breach report puts the average breach at $10.22 million, and Sift found that 80% of consumers won’t return to a brand after an account takeover there.
For years, the standard response to loyalty fraud has been detection: a report flags suspicious activity, and a person decides what to do about it. That works until the volume outpaces the team reviewing it, and most restaurant marketing teams don’t have a dedicated fraud analyst on staff to begin with.
PAR is changing that equation. Fraud prevention with Punchh Loyalty isn’t just about spotting bad activity anymore, it’s about stopping it automatically, the moment it happens.
Detection Was Never the Hard Part. Acting Fast Enough Was.
Most fraud tools generate a report. Your team has to read it, investigate, and decide what to do, by which point the damage is often already done. PAR closes that gap. Set a threshold, choose the response, and the platform enforces it the instant a guest crosses the line. No manual queue. No waiting on a fraud analyst who may not exist on your team.
Here’s what that looks like in practice:
- Rules that enforce themselves. Configure thresholds across check-in frequency, points velocity, and repeat-abuse streaks, scoped by channel (online order, POS, mobile, or dashboard). When a guest crosses the threshold, the platform automatically bans the account, deactivates it, or force-redeems points, without anyone needing to log in and make the call.
- Device-level enforcement. Banning an account used to be a speed bump, not a wall — the same person could simply create a new one from the same device. Now, when banning a guest, admins can optionally block all device IDs linked to that account — closing the side door that made bans easy to work around.
- Email-domain blocking. Bot signups using fake or disposable email domains used to require manual review to catch, often after they'd already done damage. A single rule now blocks specific domains at both signup and login.
- Referral abuse controls. Referral programs are an easy target if left unchecked: guests post their codes publicly and rack up rewards without driving any real new traffic. You can tier referral rewards by volume, cap how many referral rewards a guest can earn or redeem, and cut off incentives entirely once activity crosses a threshold you set and can adjust anytime.
- Delayed point issuance. PAR lets you add a delay between when a transaction happens and when points are actually issued. If an order gets canceled in that window, the system automatically withholds the points, a simple safeguard that prevents fraudulent earning before it's locked in.
- Time-boxed offers. Every loyalty offer can carry a unique ID that's valid for a short window, such as 15 minutes, making screenshotted or shared offer codes far less useful to anyone trying to exploit them.
- Birthday offer restrictions. Multiple sign-ups used to mean multiple birthdays, and multiple birthday rewards throughout the year. PAR can restrict birthday offers during a guest's first year if the birthday they select happens to fall in the same month they joined.
Sign-In That Can't Be Stolen
Passwords are the attack surface. Credential stuffing and phishing attempts hit loyalty programs every day, and once a guest’s password is compromised, everything tied to that account — points, payment methods, personal data — is exposed.
Passkeys remove the password as a target entirely. A passkey is a cryptographic key pair bound to a guest’s device and your loyalty program. There’s no password to phish, no credential to stuff, and nothing traveling over the wire to intercept. Face ID, Touch ID, or a device PIN confirms the guest is who they say they are. That’s the whole interaction.
What that means in practice:
- Phishing-resistant by design. Passkeys never travel over the wire, so there's nothing to intercept or replay.
- No password to reset, ever. This removes the single largest support ticket category and the single largest attack surface at the same time.
- Faster sign-in, happier guests. FIDO Alliance data shows passkeys convert 30% better than passwords and cut sign-in time nearly in half.
When You Need to Go Further: Advanced Authentication
- OTP and magic link. One-time codes and passwordless email links as a step-up or standalone sign-in flow.
- Multi-factor authentication. Policy-driven MFA for high-value actions, account changes, or sign-ins from new devices.
- Rate limiting and bot defense. Throttle login attempts, block credential-stuffing bots, and surface anomalies in real time.
- Verified identity. Government ID or document verification for compliance-grade identity assurance.
- Session management. Force logout, unlink devices, and revoke sessions across every channel from one place.
Why This Works Differently
- It acts, not just alerts. Detection and enforcement live in the same loop. Set the rule, and the platform carries it out. No weekly report to read, no manual queue to chase down.
- It's phishing-resistant by default. Passkeys are device-bound and cryptographic, going well beyond basic passwordless login, and they're included with Punchh Loyalty rather than gated behind a separate purchase.
- It's built for restaurants. These rules are configured by your own team and purpose-built for restaurant loyalty programs, not a developer project bolted onto retail software that wasn't designed for how guests actually interact with your brand across POS, mobile, and online ordering.
