First-order and promo abuse
Free delivery and ride credits claimed by new accounts again and again. The app install is the thread that links the accounts.
Real riders, real couriers. Real promotions.
Delivery and ride-hailing apps give away credit to grow, which makes them a target for promo farms, fake accounts and emulators. Fingerly adds an install ID and a set of app checks to every sensitive moment, on iOS, Android and the web.

[ 01 / 06 ]Abuse patterns
How abuse reaches delivery and ride-hailing apps.
These apps run on phones, spend money to acquire customers and onboard people who work for them. The patterns that reach them reflect all three.
Device farms and emulators
Racks of phones or emulated devices that create accounts in bulk to collect referral bounties. The native SDKs report emulators and provisioned devices.
Fake courier and driver accounts
Accounts opened to collect sign-up bonuses or to resell a verified profile. The same install behind several driver sign-ups is a lead for review.
Cloned and tampered apps
Cloned or patched apps that run many accounts side by side or hide what the device reports. Cloned-app and tampering signals are reported by the SDK.
Account takeover and stored payments
Stolen logins used to order or ride on saved cards. A device the account has never used is worth knowing about before the order.
Payment and refund abuse
Orders paid with stolen cards, and refund claims repeated across accounts. Device context is an input beside your payment provider.
[ 02 / 06 ]Pattern to decision
From pattern to decision.
In apps the device is recognised by a random install ID the SDK keeps for the app, never by its hardware. It identifies the installation, not the phone.
01
Promo and referral farms
Credit for new customers, once.
Identify at signup and when a promo code or referral is applied. Count redemptions per install ID and read device farm and emulator signals. The usual first decision is to hold the credit for the cluster and review it together.

02
Fake courier and driver sign-ups
Look before a profile is verified.
Identify at courier or driver onboarding. Several sign-ups on one install, or from an emulator or cloned app, are worth a manual review before the profile can take jobs.

Tampered and cloned apps
What the app says about its own device.
Instrumentation, rooted or jailbroken devices and cloned apps are reported by the native SDKs with weights you control. Decide on the server, because an app can be patched to report anything.

Orders on stolen logins and cards
Make checkout safer, not harder.
Recognise the installs an account normally uses and add a step only when a login arrives from a new one that also carries automation or an anonymised network. Combine the result with your payment provider.

[ 03 / 06 ]Integration
Integrate at the right moments.
Four habits keep a policy for delivery and ride-hailing apps effective without turning it against genuine customers. A production identification is billed per request, from $0.0025, so it is worth placing where it earns its cost.
- 01 Identify at the moment
Call identify in the app at signup, when a promo or referral is applied, at courier onboarding and before the first order from a new install, not on every screen. Pass your own account reference as the tag.
await fingerly.identify({ tag: "promo-redemption" }) - 02 Verify on your server
Send only the request ID from the app to your backend, read the stored result with a secret key, and check that its tag matches the action. The app can be modified, so the server decides.
- 03 Observe before you enforce
Run in monitoring mode first. Family phones, shared tablets and corporate networks are ordinary, so measure who a rule would affect before enforcing it.
- 04 Act in proportion
Hold credit and payouts for clusters instead of closing accounts, step up for uncertain sessions, and give a genuine customer or courier a way to be cleared.
[ 04 / 06 ]Moments
Where to check, what to do.
Where a delivery or ride-hailing app usually places the check and what it reads there.
| Moment | Identify when | Read | Usual first decision |
|---|---|---|---|
| Signup | The account is created | Install ID, emulator, device farm | Hold promo credit for clusters |
| Promo redemption | Before the discount applies | Visitor ID, high activity | Review repeat redeemers |
| Courier onboarding | Before verification | Visitor ID, cloned app, emulator | Manual review before activation |
| First order from a new device | Before payment | Suspect score, tampering | Step up above your threshold |
| Payout | Before it is released | Visitor ID, instrumentation | Hold and review linked accounts |
Every decision is yours. Fingerly returns the visitor ID, the signals and the suspect score, and never blocks a request by itself.
[ 05 / 06 ]Questions
Questions about delivery and ride-hailing apps.
How a delivery or ride-hailing app uses device fingerprinting, and what an install ID can and cannot do.
Talk to the teamHow do delivery apps prevent promo and referral abuse?
With Fingerly, a delivery app identifies the install at signup and at redemption, stores the visitor ID with each claim and reviews repeat claimants. Device farm and emulator signals show bulk operations, and your policy decides whether to hold the credit.
Can Fingerly detect emulators and cloned apps on Android?
Yes. The Android SDK reports emulators and virtualised Android, cloned apps, rooted devices, instrumentation and interception as signals with weights you control. Work profiles on managed devices are tuned so that an enterprise fleet is not reported as cloned apps.
Does the install ID follow the phone or the person?
Neither exactly. In an app, Fingerly recognises a random install ID the SDK keeps for the app, never the phone hardware. Removing the app or clearing its data may start a fresh ID, which is why emulator, farm and cloned-app signals matter beside it.
Which mobile frameworks does it support?
Native iOS and Android, plus React Native, Flutter and Lynx bridges over them. They send the same identify request as the web SDK and return the same response fields, so one backend integration covers every surface.
Does it replace my payment or driver verification?
No. Fingerly does not verify identity documents or authorise payments. It adds device and network context as one input beside the checks you already run, and returns a suspect score your own rules act on.
