On your phone
An electronic signature on iPhone or iPad. Open the PDF, place the stamp, sign. The document stays on the device.
Sign a PDF with your own certificate. The file stays on the device.
TapSign signs PDFs on iPhone, iPad or Mac with the certificate on your USB token or the Romanian electronic ID card. The file is never uploaded and there is no account to create. Anyone, anywhere, can verify the signature in Adobe Acrobat - and across the EU a qualified signature carries the legal weight of a handwritten one.
- PAdES / ETSI CAdES
- eIDAS compatible
- Verifiable worldwide
- Nothing uploaded
Sign on your phone, with an ID card, or with a token
With the electronic ID card (CEI)
The Romanian electronic identity card signs over NFC on iPhone. For contracts and declarations, without a token.
With a SafeNet USB token
A qualified signature with the certificate on the token you already own - SafeNet eToken 5110 from certSIGN, DigiSign, Trans Sped or another issuer. Plug it into an iPhone, iPad or Mac.
Three taps, under a minute
-
01
Open the document
Share a PDF to TapSign from Mail, Files, WhatsApp or anywhere else. It opens straight away.
-
02
Place your signature
Tap the page where the stamp belongs, drag it, resize it. Or sign invisibly, which is just as valid.
-
03
Sign and send it back
Connect your token or hold the ID card to the phone, enter your PIN, and share the signed file.
Everything you need, nothing you do not
Your certificate, your key
The private key stays on the token or the card. The chip signs. We do not.
Signature styles
Eight ways for the mark to look on the page, from the Standard Acrobat layout to a plain signature line. Or none at all.
Verify any signed PDF
Open a signed document and TapSign recomputes the digest and checks the signature against the certificate inside it. On your device.
Multiple signatures
Sign a document that someone else already signed. Earlier signatures stay intact and verifiable.
Reason and place
Add why you signed and where, recorded in the signature itself rather than typed onto the page.
Works with what you own
Any qualified token issued in Romania - including SafeNet eToken from certSIGN, DigiSign or Trans Sped - over USB-C on iPhone and iPad; the electronic ID card over NFC; and any CCID reader on a Mac.
This is what appears on the page
Eight ways the mark can look, or none at all. Every image below is the real output - the same code that writes into your signed PDF drew these.
Prefer nothing on the page? Sign invisibly. The signature lives inside the document and is just as valid.
The document never reaches us
There is no upload step to opt out of. Signing happens entirely on your device, your PIN goes to the token and nowhere else, and we do not run a server that sees your files.
