Tenants can't tell if an agent really represents the owner before sending a deposit
A r/Bangkok post warns of an agent who faked an owner's authorization letter to collect a tenant's first deposit at a luxury condo; the advice is to confirm the owner with building management and pay only the owner's account. Another renter says every agent asks for a booking fee of about half a month's rent upfront.

Payee Match: scan the owner's ID and the bank screen to compare names
Before paying, the tenant photographs the owner's ID copy or title deed and the bank app's recipient screen. Claude vision compares the two names and the unit, and says match, mismatch or cannot tell, with what to ask.

Owner Callback: an agent that independently confirms with the owner by phone
The tenant enters the unit and the owner's phone number from the building office. The agent calls or texts the owner in Thai and English: 'did you authorize this agent to collect this amount to this account?' and reports the answer before any money moves.

Listing Twin Finder: paste listing photos and see the same pictures elsewhere
Fake or reposted listings reuse photos. The tenant uploads the listing pictures and the tool runs Google Cloud Vision web detection to find the same images on other pages, with different phone numbers or prices.

Booking Pad: a pocket pad of receipt slips with payee name, owner name and a verify QR
A tear-off pad of printed bilingual booking receipts for viewings. Blanks for owner name, payee name, unit, amount and date, with a QR to the name-match checker. The agent will not get a deposit without filling and signing a slip a tenant can show later.

Lease Reader: photograph the contract and get the odd clauses flagged
A tenant photographs the booking form and lease. Claude reads the Thai, explains each clause in English or the tenant's language, and flags unusual items such as large booking fees, vague deposit return terms and payee names that differ from the owner.
