Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-8d5ae49d71846c9a quantitative
AC Group's Tap&Go contactless card has been used on Kigali's public buses since 2015
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The project record describes Tap&Go as 'Used on all public buses in Kigali to pay for transport fare', and names AC Group as the organisation behind it. The 2015 start is the operator's own dating.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Do4Africa — Tap & Go project record (reference)
  2. AC Group (operator)
Claim 2 clm-cafae51e6ff411a1 descriptive
the company has taken it to Yaounde in Cameroon as well
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The project record states 'This project is implemented in Rwanda as well as in Cameroon', and the East African reporting covers the Cameroon deployment.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Do4Africa — Tap & Go project record (reference)
  2. The EastAfrican (press)
Claim 3 clm-a921335ce7b4aa5e quantitative
It reports more than 298 million journeys, and says bus operators recover 30 to 40% of the fare revenue that cash collection used to lose
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Both figures are AC Group's own, stated on its Tap&Go page: journeys facilitated and the share of previously lost revenue that operators recover.
Caveat
The operator's own figures. Its site is now a JavaScript application that serves no readable text to a plain request, so no locator string is recorded against them.

  1. AC Group (operator)
Claim 4 clm-e195e316dc45c538 quantitative
more than 298 million journeys since 2015, and bus companies recovering 30 to 40% of the fare revenue previously lost to cash collection
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The two headline figures the operator publishes for Tap&Go.
Caveat
Operator figures, unaudited and without a stated method for either the journey count or the recovery range.

  1. AC Group (operator)
Claim 5 clm-bd40c08bd346a696 descriptive
No independent evaluation of either number was found for this entry
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The recovered-revenue range and the journey count appear in the operator's material and are repeated in the press coverage that cites it. Nothing read for this entry measures either independently.
Caveat
A statement about the state of the evidence, made by this entry rather than by any source.

  2. The EastAfrican (press)
  3. Startup Guide (press)
Claim 6 clm-6f44ae3c28ffc481 descriptive
What Tap&Go is reported to have delivered is recovered fare revenue - money that used to go missing between the passenger and the bus company - and that is the number the company leads with, not journey times or waiting
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The operator's own headline claims for the product are the journey count and the recovered-revenue range. No figure for journey time, waiting time or service reliability appears in the material read for this entry.
Caveat
An observation about what the operator chooses to publish, drawn from its own material.

  1. AC Group (operator)
Claim 7 clm-4624f10b3188c053 descriptive
it is what carried the same product across a border
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The East African covers the Rwandan firm's cashless bus system being taken to Cameroon, and the project record confirms the system runs in both countries.
Caveat
No claim-specific caveat recorded

Source dossiers and revision state

This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.

unreviewed Revision 2026-08-26-p1-quality-uplift effective 2026-08-26 · created 2026-08-26

Awaiting operator and domain-expert review; publication of this revision implies neither.

Erratum on this revision's envelope. The snapshot, its hash and its permanent link are untouched.

  • createdAt previously read 2026-08-26T16:35:00Z. The batching script that produced this revision advanced createdAt into the future to satisfy the strictly-increasing order the validator requires per entity. The value never recorded a real event; the corrected value is the moment the revision provably existed in the repository. Corrected to 2026-08-26T14:11:55Z on 2026-08-27; evidence: first appears in commit 5fac751ec9, committed 2026-08-26T14:11:55Z.

Known limits of this passport
  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
  • A missing archive, publication date or content hash is shown as null rather than inferred.
  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
