Direct Answer and Scope
Start the cost comparison with the physical item. Ask for separate written entries for the plaque or memorial medallion, production, attachment hardware, mounting or installation, delivery, and any later remounting. Request the material, dimensions, attachment method, included work, excluded work, and charge for each field. These are questions for a written offer, not statements that a particular product, installation method, or service is available.
For digital setup, request separate terms for initial content setup, later content changes, platform or hosting access, account administration, domain registration or renewal, and redirect management. Each entry should state whether the charge is one-time, recurring, conditional, or unknown; the billing interval; what is included; and the date of the written terms. Do not convert a blank field into an included feature or a zero-dollar charge.
Treat the QR image and the destination it opens as separate evidence states. Record who controls the destination, account, domain, and any redirect only when current written documentation states those details. Add a human-readable fallback field so the destination can be recorded separately from the QR image. None of these fields establishes continued access, renewal, transfer, export, or restoration unless the relevant term is documented.
How to Use the Evidence
Library of Congress preservation guidance supports asking whether an independently readable copy exists outside a commissioned service. For a hosted memorial, request a written answer about whether an export is offered, what information it contains, which metadata accompanies it, and what file format is delivered. Keep the answer unknown when those details are absent; do not assume that saving a visible web view captures the memorial completely or preserves its functions.
The same guidance treats preservation as an active review process rather than a one-time promise. Ask what periodic readability checks the family would need to perform on exported files and whether any related assistance carries a charge. Record independent copies and tests separately from live platform access. Continued access to a hosted memorial does not establish possession of an independent copy, and possession of a copy does not establish that it has been tested or can restore a live memorial.
Use the preservation guidance to form questions, not to create a price benchmark. It does not provide a California price, a vendor quote, a product lifespan, or a service commitment. Possible export, migration, replacement, and review costs therefore need their own unresolved fields until current written terms identify an amount, frequency, scope, and responsible party.
Decision Framework
Organize the written total-cost worksheet into four groups. Under physical and mounting costs, include the marker or plaque, attachment components, mounting labor, delivery, replacement, and remounting. Under content and setup, include initial setup, content preparation, later changes, and any stated metadata work. Under recurring service, include each platform, hosting, domain, redirect, account, or renewal charge. Under exit and continuity, include export, migration, transfer, closure, and handoff fields.
For every field, request the charge, billing frequency, start point, renewal point, included work, excluded work, and document date. If a vendor combines multiple elements, ask for the combined scope in writing and retain separate status fields for the underlying QR image, destination, account, domain, redirect, export, independent copy, and fallback record. A combined description should not erase an unanswered control or continuity question.
Build the exit-cost worksheet before comparing totals. Ask whether an independently readable export is offered, what content and metadata it includes, what format is delivered, and whether creating or delivering it has a separate charge. Add unresolved fields for migration assistance, account handoff, domain or redirect transfer, final content delivery, and replacement of the physical marker. These remain questions unless current documentation states the capability and its terms.
Do not calculate a vendor total from missing figures. A written total should identify the period it covers and distinguish initial charges from renewals, conditional work, replacement, maintenance, and exit costs. If an amount, occurrence count, or billing interval is absent, preserve it as unknown. That approach prevents an unanswered field from being treated as included, excluded, or free.
Evidence Limits and Unresolved Questions
No validated vendor, product, platform, feature, price, account-control term, export method, file format, backup process, restoration process, review, availability statement, or turnaround record is attached. There is therefore no supported California amount or range for a plaque, mounting, platform access, renewal, content setup, migration, replacement, maintenance, or exit service. Vendor-specific entries must remain unknown until current primary documentation addresses them.
The unresolved questions include who controls each digital layer; whether a human-readable fallback exists; whether export, migration, transfer, backup, restoration, or continuity handoff is offered; what any export contains; and which charges recur or arise later. The Library of Congress guidance supports preservation questions and periodic review, but it does not establish vendor features, continued service, file readability, or long-term link operation.
Evidence behind this page
Each point below is restricted to what the cited primary source supports. Administrative listing status is not a quality endorsement.
| Evidence | Supported point | Scope and limitation |
|---|---|---|
| Evidence 1 | Ask whether an independently readable preservation copy exists outside the commissioned service. | Do not claim that two copies prevent loss, approve a medium or location, or treat a vendor-hosted copy as independent without evidence. |
| Evidence 2 | Describe preservation as an active review process rather than a one-time permanence promise. | Do not guarantee readability, prescribe a universal replacement schedule for every medium, automate a reminder, or claim that an online service will remain available. |
| Evidence 3 | Ask whether a hosted memorial provides an independently readable export, what the export contains, and which metadata accompanies it. | Do not claim that a vendor offers export, that a browser-saved page is complete, that an export preserves functionality, or that a format will remain readable. |
| Evidence 4 | Separate live memorial availability from possession of independent exported copies and from testing those copies. | Do not promise website uptime, domain renewal, redirect continuity, service survival, full export, restore capability, or long-term link operation. |
| Evidence 5 | Publish official method guidance and vendor-question fields only, leaving vendor-specific values unknown until a separate primary-evidence manifest passes review. | Do not name, list, rank, recommend, contact, quote, compare, review, or imply a feature or capability of any vendor or platform. |
| Evidence 6 | Keep every layer visible and unresolved rather than using a QR-present badge as proof of persistence. | Do not guarantee a QR code, link, URL, domain, redirect, account, host, export, backup, restore, or memorial will remain accessible. |
Questions people ask
How much does it cost to put a QR code on a gravestone?
No supported amount or price range can be stated because no validated vendor price record is attached. Request a written, itemized offer that separately addresses the physical plaque or memorial medallion, production, mounting, delivery, initial digital setup, recurring platform or renewal terms, replacement, maintenance, export, migration, and exit charges. Leave every undocumented figure unknown.
Which one-time and recurring cost fields should I request?
One-time fields can ask about the physical marker, attachment components, mounting, delivery, and initial content setup. Recurring fields can ask about platform, hosting, account, domain, redirect, or renewal charges. Also request conditional fields for content changes, maintenance, replacement, and remounting, plus exit fields for export, migration, transfer, closure, and continuity handoff. Treat each capability and amount as unknown until it appears in current written terms.
Can this checklist estimate a vendor's price?
No. It can organize written cost components and preserve unanswered fields, but it cannot produce an estimate, range, average, package price, or total without validated price records or a separately supplied calculation. It also cannot establish that a vendor offers a particular plaque, platform, export, migration, replacement, or continuity feature.
