Now keep it safe: three things
- Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
- Save this receipt to your camera roll.
Keep the receipt file too. The image is a handy copy; checking needs the file.
- Email it to yourself.Email it to myself
Your mail app opens a draft. Attach your receipt image and receipt file. Don’t attach your photos or documents. Timevolt does not send it or know whether it was sent.

How to keep notes that hold up
Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.
- Write it down straight away, on paper or in the box on a step.
- Put the date, time and place at the top, and who you spoke to.
- Use their words where you can; separate what you saw from what you were told.
- Sign or initial a paper note, photograph it and add the photo.
- Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.

Scope of the cited rule.
Pennsylvania section 2201(b) addresses a qualifying confirmation between merchants and a ten-day objection period for the statute of frauds. Silence alone does not establish that a contract was made or that every term was accepted. Other states and transactions need their own scope check.
As of October 30, 2026.

Real cases where dated records mattered. We don’t claim a time receipt would have changed the result.
US federal, D. Connecticut · 2007
Keep the revised instructions with the order
A maker and supplier disputed which order and revised work sheet set the rules for the parts. A dated fax recorded the change. The court let some assets be held, less than sought, but did not decide a final winner.
This was an interim ruling based on a preliminary showing, not a final decision on liability.

Resolve drawing conflicts before relying on them
A contractor and an agency disputed pipe and valve sizes in drawings used to bid. The case went back to decide if the clash was plain enough to ask about before bidding. If hidden, a fair reading could still lead to a price change.

Positions below refer to the cited rule or record type, not endorsement of Timevolt. This service is not represented as an eIDAS qualified timestamp provider. A non-qualified timestamp does not receive the qualified timestamp presumption.
UCC 2-201 statute of frauds (sale of goods)
A writing signed by the party to be charged is needed for goods over $500. Under the applicable state UCC rule, a qualifying confirmation between merchants can satisfy the statute of frauds against a recipient who does not object within ten days. Silence alone does not establish a contract or acceptance of every term.
The page does not say whether electronic records count. A dated receipt could help show when a confirmation existed, but it does not show receipt or signature.

Read the sourceFederal Rule of Evidence 902(13) and 902(14)
Electronic records and data copied from a file can be self-authenticating with a qualified person's certification and advance written notice. The 2017 Committee Note says identical hash values reliably show exact duplicates.
Supports hash-based identification of a file as an exact copy, via certification. It does not cover timestamps or Bitcoin anchoring specifically, and the court still decides admissibility and weight.

Proves / Doesn’t prove
Proves
A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.
Doesn’t prove
It does not prove you sent them to the supplier, that the supplier received or accepted them, who wrote them, or that the spec is correct or governs the purchase order.
This cannot establish delivery, agreement, correct units or which terms govern.
These are the bounds of a completed proof. The local tester does not establish any time. The chosen court, scheme or regulator decides what to accept.
Questions, answered plainly.
Your file stays on your device. During normal receipt creation, your device sends a randomized code made from its fingerprint, plus encrypted recovery data. It doesn't send the plain fingerprint or the random value that opens the code. Keep the original file and the complete receipt for checking. Privacy Policy.
Does a time receipt prove my supplier received the spec?

Context for this answerWhich revision should I fingerprint?
Fingerprint the exact released file set for each revision, one receipt per revision, and record the revision letter in your issue log.
What if I change one character in a drawing?
The fingerprint changes completely, so the old receipt matches only the old file. That makes superseded revisions easy to tell apart.
Will a court accept it?
Courts decide. US federal rules allow electronic files to be authenticated by hash value through a certification, but a receipt alone is not a ruling on admissibility.
