原文外掛簡介

Inkslip is a complete digital waiver desk inside WordPress: publish a liability waiver or release form, and people sign it on their own phone or on a tablet at your counter in kiosk mode, which clears itself after every signer. One parent or guardian signs for several children in one go. Every signed waiver is a tamper-evident record: the exact text is frozen as a version, and each record is fingerprinted and chained so a later change can be detected. No form plugin, shop plugin or outside account is needed, and everything stays on your own site.
Built for gyms, yoga and fitness studios, kayak, bike and equipment rental shops, climbing walls, trampoline parks, riding stables, tattoo and piercing studios, camps, schools, volunteer groups, classes, tours and events — anyone who needs every participant to sign a waiver form or a release of liability before they take part.
Starter waivers
Pick a ready-made liability waiver template and edit it in plain words: a general activity waiver and release of liability (good for events and classes), a gym and fitness waiver, an equipment rental agreement and waiver, and a photo and video release form. They include assumption of risk, a release, and a hold-harmless sentence.
Starters for particular businesses, each ready to edit: a tattoo consent form (tattoos, piercing and permanent makeup, with aftercare), a medical release form for a child (permission to get a child medical care when the parent cannot be reached), a permission slip for field trips, camps and outings, a hold harmless agreement for anyone using your venue or equipment, a volunteer waiver, a horse riding waiver, and a trampoline park waiver that is also a climbing waiver for bouldering and climbing gyms. Choose the questions to ask (e-mail, phone, date of birth, address, emergency contact, medical notes, photo consent, your own tick-boxes such as “I can swim”) and how long a signature stays valid: always, 6 months, 1 year or any number of days.
Initial each clause, and a health questionnaire
Tick the sections of your waiver that matter most and the signer types their initials in an “Initial here” box at the end of each one, before they can go on. Add your own yes/no health questions (“Do you have a heart condition?”) as a short medical questionnaire: each needs a Yes or a No, and a Yes can ask the person to explain. The initials and the answers are part of the signed record, its fingerprint and the PDF.
Signed on any phone
Share a link or print the QR code. The online waiver opens on any phone, one simple step per screen: read, your details, children, sign. People sign with a finger, a pen or the mouse on a smooth signature pad, or type their name instead. Before signing they tick that they have read the waiver and that they agree to sign electronically, then press “Sign and agree”. You can also put the electronic waiver on any page with the “Waiver signing form” block or the [inkslip] shortcode.
Kiosk mode for a counter tablet
Turn any tablet into a waiver kiosk: a big “Tap to sign” screen with your logo. After each person signs it says thank you and resets for the next one, and nothing of the previous signer is ever visible — no back button, no autofill, nothing kept on the tablet. A form left alone clears itself, a staff PIN leaves kiosk mode, and the screen stays awake. Each tablet has its own link that you can disconnect at any time.
Children and guardians
A parent or legal guardian signs for themselves and several children at once — a parental consent form and a minor waiver in one signing. Ages are worked out from dates of birth in your time zone. Anyone under the age of majority (18, or 19 or 21 where that is the rule) can only be signed for by an adult, and every child gets their own record, so you find a child by name later.
Check-in lookup: valid or expired
At check-in, type a name, an e-mail or a phone number. Each person shows a green “Valid until …”, an amber “Expires in 7 days” or a red “Expired”. Children show who signed for them. Open any record to see everything, download its PDF, or verify it. Export signed waivers to CSV (formula-safe for spreadsheets).
A tamper-evident record
When you publish a waiver, its exact text is frozen as a version; editing it later makes a new version and never changes what people already signed. Every signing is fingerprinted (SHA-256) together with the version’s fingerprint and the previous record’s fingerprint — a chain. Verify recomputes a record, or the whole chain, and names the exact record that changed or went missing. The record keeps what was agreed and by whom: the signer’s details, the drawn or typed signature, the time, the device and (optionally) the IP address.
PDF copy for every signer
Each signer gets a waiver PDF by e-mail from your site: the exact text they signed, their answers, the children, the signature, and a record details page with the fingerprints. If your site’s e-mail fails, the signing is still saved and the person can download the PDF on the spot. PDFs are made on demand and never left as public files.
Your data stays on your site
Waivers, signatures and PDFs live in your own WordPress database. WordPress’s personal data export and erase tools work with signed waivers, suggested privacy policy text is included, and you can set a retention period. Unlimited waivers, unlimited signers, unlimited tablets.
How Inkslip is different
Most signature plugins add a signature field to a form plugin, or put a pop-up on a shop checkout. Inkslip is the whole waiver flow on its own:

kiosk mode for a counter tablet that resets between signers;
one adult signing for several children, with ages from dates of birth;
a check-in lookup that shows who is valid and who has expired;
frozen waiver versions and a fingerprinted, chained record with a Verify button;
a PDF copy e-mailed to every signer;
no account, no API key and no outside service.

Privacy and external services
This plugin does not connect to any external service. It makes no outbound request of any kind: no API, no tracking, no analytics, no fonts or scripts from other sites, no CAPTCHA. Spam is stopped with a single-use form token, a hidden honeypot field, a minimum fill time and a rate limit. The only thing that leaves your site is the signer’s PDF copy, sent with your site’s own e-mail.
The Waivers screen has one ordinary link, “Get early access”, to a page about a possible paid service. Nothing is sent when the screen loads; the page opens in your browser only if you click, and your e-mail address reaches us only if you type it there.
