e-signatures, over WhatsApp
Send a PDF to Inkline. It comes back signed — real signature, certificate and all — in about 20 seconds. No app. No account. No “please find attached.”
Forward any PDF to Inkline and say who signs — a name and a number. That's the whole setup.
They tap one button and sign with a finger, right on their phone. Nothing to download, no account to make.
Both sides get the signed PDF back in chat, with a certificate showing who signed, when, and a tamper-evident fingerprint.
Every signed document carries a certificate. The signer is verified by their WhatsApp number — harder to fake than an email link — and the full trail is recorded: sent, opened, signed, delivered. Simple electronic signatures like these are recognised in the UK and EU under eIDAS.
Landlords closing tenancies the same afternoon. Freelancers who'd rather not chase email. Agents whose clients live in WhatsApp. Families doing business London-to-Lagos, where a signature used to mean print, sign, scan, resend — and now means three messages.
