The comparison in one page
Scope
Paper consent is the familiar process: a printed information sheet and consent form, a conversation with a member of the study team, handwritten signatures and dates from the participant, the person obtaining consent and sometimes a witness, and a signed copy for the participant. The original goes into the investigator site file.
eConsent presents the same information on a screen, usually with the signature captured electronically. A good implementation is more than a scanned PDF: it controls which version of the document is shown, makes required fields mandatory, confirms the signer's identity, records who did what and when, and produces a signed copy. For the definition and regulatory background, see our plain-English eConsent guide and the electronic informed consent regulations guide. This page does not repeat those; it is about choosing between the two routes.
One fact is common to both: consent is a process, not a signature. In the US, the FDA and OHRP joint question-and-answer document on electronic informed consent (published in December 2016) says electronic consent should contain all the required elements of informed consent and the process should allow questions, according to the summaries we checked. The same applies on paper. If the conversation was rushed, neither format rescues it.
Head to head
Written in general terms. A well-run paper process can beat a poorly configured electronic one, and the reverse.
| Dimension | Paper consent | eConsent |
|---|---|---|
| Version control | Depends on staff using the current print run; superseded forms can stay in circulation | The system shows the approved version; older versions can be retired centrally |
| Completeness | Missing initials, dates or signatures are found at review, sometimes weeks later | Required fields must be completed before the signing step can finish |
| Signature and identity | Handwritten signature; identity checked by the staff member in person | On-screen signature plus a verification step such as a one-time email code; countersignature by authorized staff |
| Understanding | Staff explanation; reading level depends on the printed text | Same conversation, optionally supported by structured sections; effect on understanding depends on design and should be judged by your ethics committee |
| Remote participation | Post, courier or an in-person visit; slow, with weak identity assurance | Participant signs on their own device; staff countersign remotely |
| Evidence later | Wet-ink original in a binder; dates are what was written | Time-stamped log of views, signatures and countersignature; signed copy exportable |
| Access and inclusion | Works with no device or connectivity; suits people who prefer paper | Needs a device and some comfort with it; offer an alternative route |
| Cost and effort | Print, courier, file, scan, and find on audit; staff time per form | Setup effort and software cost; less filing, less chasing; see our eConsent cost per study breakdown |
Prices differ widely, and neither route is free: paper costs staff time and storage, electronic systems cost licence or setup. Compare your own numbers.
Where each route breaks
Paper consent usually fails quietly. A page is missing from the stapled set, the participant initialed one box and skipped the next, a consent form from before an amendment gets used for a late enrollee, or the date was written in a hurry. None of these is exotic, and in our experience of how sites describe their audits they are the common findings. The cost shows up late, at monitoring or inspection, when the participant may be unreachable and the fix is a note to file.
eConsent fails differently. The risk is a flow that is clumsy on a small phone screen, a verification email that lands in spam, a participant who cannot get online, or a team that treats the electronic form as a replacement for the conversation. Misconfigured identity steps and untested versions are another risk, which is why the electronic route needs a rehearsal with practice participants and a back-up plan for people who cannot use it.
The honest summary is that eConsent moves errors from "found later" to "prevented at the time" for the things a system can check (completeness, version, sequence, signer verification) and does nothing for things it cannot check (whether the participant understood). Keep that distinction in your standard operating procedure.

Switching
Deciding
A short route that works for small and mid-sized teams.
In clinic only, remote only, or both? Remote or multi-site enrollment tips the balance toward electronic.
Age, access to a device and comfort with it. Where electronic access is uncertain, plan paper as the fallback and say so in the protocol.
Many committees need to review the electronic presentation and the identity method. Ask early what they need to see.
Version history, signer verification, countersignature, witness or representative signatures. Match these to the protocol, not the feature list.
Run practice participants through electronic and paper, and compare the records they leave behind.
A one-page SOP: who obtains consent, how identity is checked, where signed copies live, what happens when someone chooses paper.
Running both
Offering both is common and sensible. These points keep the records consistent.
Identical content and version number, approved by the ethics committee. A drift between them defeats the purpose of version control.
Record paper consents in the study record too, so enrollment reports and monitoring see every participant, not only the electronic ones.
Both routes should give the participant a copy. Check what your regulator and committee expect about printed copies and any linked web material.
The same person should be able to explain either route, and know how to switch a participant who changes their mind.
Where wet-ink originals go, who holds the key, and how this fits your retention plan. See clinical trial data archiving and retention.
Witness, representative and assent flows exist on both routes. See impartial witness eConsent and legally authorized representative consent.
Regulatory context
Neither FDA nor the EU sets electronic consent as mandatory or paper as forbidden. The joint FDA and OHRP guidance on electronic informed consent (Federal Register notice of 15 December 2016) is a set of questions and answers. According to the summaries we checked, it says electronic consent must contain all required elements, participants should be able to move back and forward and to stop and resume, and electronic signature systems fall under Part 11 where Part 50 applies. Check the original for exact wording and for what it says about paper options and copies.
In practice, the ethics committee or IRB reviews your consent process, including the electronic presentation, so ask them what they need to see. For a deeper regulatory map, see the electronic informed consent regulations guide, and for signatures in particular, electronic signatures for clinical trials. Capture provides 21 CFR Part 11-aligned controls; validated use is a shared responsibility with the sponsor. This is not legal advice.
It is better at controlling versions, enforcing completeness, time-stamping events and supporting remote enrollment. Paper is simpler and needs no device. Neither guarantees understanding, so the quality of the consent conversation matters most. Many studies offer both.
Regulators accept electronic informed consent when the required elements are present and the signature system meets the applicable rules, such as 21 CFR Part 11 in the US. Ethics committees and IRBs review the process, so check what yours needs. This is general information and not legal advice.
Summaries of the FDA and OHRP guidance suggest participants should be able to use paper where needed or preferred, and many sponsors keep a paper route for that reason. Confirm in the original guidance and with your ethics committee, and describe the paper route in your procedure.
It can prevent errors a system can check, such as missing signatures or dates, wrong version and skipped sequence. It cannot check whether the participant understood. Your team still needs a proper consent conversation either way.
It depends. Paper costs printing, courier, filing and staff time to check forms. Electronic systems cost licence or setup effort. Compare both against your sites, participant count and number of consent versions rather than assuming one is cheaper.
The participant signs on screen after acknowledging the legal-binding statement and confirming an email one-time code. Authorized staff countersign with password re-authentication, and the document is fully executed only after that. Each signature is linked to the exact document content, and the signed PDF includes timestamps and audit trail.
Yes. Capture offers eConsent templates including basic clinical trial, biobank, pediatric assent and observational study at /templates/consent. You edit the text to match your protocol and have it approved by your ethics committee before use.
