Quick safety tips when using any Sri Lankan mobile payment app

• Prefer bank‑backed wallets or apps approved/endorsed by the Central Bank. (ezcash.lk, payhere.lk)
• Enable biometric login + PIN and keep the app updated. (nationstrust.com, hnb.net)
• Use LankaQR/EMV‑compliant QR payments at merchants (safer than manual card entry). (lankapay.lk)

If you want, I can (a) rank these by user‑adoption or merchant acceptance, (b) show download links and country availability, or (c) compare fees/features for two or three specific apps — tell me which.
