Frequently asked questions
Answers for owners, managers, and cashiers.
General
Is a screenshot still enough?
No. HASKA Pulse verifies the actual wallet notification on an authorized device. Screenshots can be easily faked.
Does my cashier need the owner’s phone?
No. The gateway device handles SMS evidence so the owner’s phone is never shared or needed at the checkout counter.
Security
What happens if the same SMS is delivered twice?
Server-side fingerprints and idempotent event IDs prevent duplicate payments. It will be ignored.
Can old payment records be edited?
Transactions are immutable. Confirmations can be reversed, but the original evidence stays intact in an append-only log.
Are my banking details safe?
Yes. Pulse only parses the specific notification SMS and sends a cryptographically signed payload. It does not access your actual bank account.
Technical
Do I need a special device for the gateway?
Any dedicated Android device capable of receiving SMS and running our lightweight app will work perfectly.
How fast is the verification?
Near-instant. Using Server-Sent Events (SSE), the dashboard updates milliseconds after the gateway processes the SMS.
Pricing
Is there a free trial?
Yes, our Starter plan is completely free and allows up to 200 payments per month for a single branch.
Can I cancel anytime?
Absolutely. There are no lock-in contracts for Starter and Business plans.
