Free PromptPay QR generator
Enter your PromptPay ID (phone / national ID / e-wallet) and an optional amount to get a QR instantly. Generated fully offline into your own account — BillsOS never sees the funds and charges no fee.
A single static QR works for everyone, but the payer types the amount (and can mistype). BillsOS embeds an EXACT-amount PromptPay QR on every invoice, so the client scans and pays straight into your own account.
