Chargeback evidence capture at the terminal is the single highest-leverage process change available to a Caribbean merchant who is losing disputes to friendly fraud. This piece explains what it is, how it works on a modern terminal, what evidence the issuer actually accepts, and why most Caribbean merchants are currently losing chargebacks they could be winning.
A chargeback arrives 30 to 120 days after the original transaction. The customer disputed the charge with their issuing bank. The issuer pulled the funds from the merchant account and is asking the merchant to prove the transaction was legitimate. The merchant has 10 business days to respond with evidence. If the merchant has no evidence — or the wrong kind of evidence — the chargeback is finalized and the merchant eats the loss.
On a typical Caribbean small-merchant terminal that does not have chargeback evidence capture built in, the merchant has roughly nothing to respond with. The original transaction was a tap or a chip read that printed a paper receipt the customer did not take. There is no signature. There is no photograph. There is no documentation tying the cardholder to the purchase. The chargeback wins by default.
What chargeback evidence capture actually means
Evidence capture is the terminal-side process of recording, at the moment of the transaction, the documentation an issuer will accept as proof the cardholder authorized the purchase. On a modern terminal, this includes:
- A digitally captured cardholder signature on the touchscreen at the moment of payment. The signature is timestamped, bound to the specific transaction ID, and stored against the merchant account.
- A transaction-time photograph from the terminal camera, if the merchant has the optional terminal model with one. Used in higher-risk merchant categories where photo evidence makes friendly-fraud claims easier to reject.
- The terminal location stamp — GPS coordinates of the terminal at transaction time, which proves the cardholder was physically present at the merchant location.
- The EMV chip-read or contactless tap event log, which proves a physical card with the cardholder PIN or biometric authentication was presented.
- The receipt PDF generated and emailed to the cardholder, if the cardholder opted into email receipts.
A terminal that performs proper chargeback evidence capture creates all of this automatically, at the transaction moment, without any merchant intervention. The evidence is stored against the transaction ID. When a chargeback arrives, the merchant pulls the transaction record, sees the full evidence package, and submits it to the issuer with one click.
Why most Caribbean merchants do not have this
The terminal that most Caribbean small merchants run on was sourced from a regional bank that leased it from a US or European parent platform. The terminal was certified for card acceptance. It was not certified for chargeback evidence capture. Those are different feature sets, and Caribbean merchants almost universally received the cheaper terminal that handles acceptance but does not handle evidence.
The cost difference between the two terminal types is small — maybe $30 to $80 in unit hardware. But the chargeback economics over a year are different by an order of magnitude. A Caribbean merchant doing $25,000 a month in card volume might absorb $400-$600 a month in chargeback losses on a terminal without evidence capture. With evidence capture, that drops to under $100 a month. The terminal hardware difference pays back in roughly three weeks.
How chargeback evidence capture changes the dispute math
On a terminal without evidence capture, the merchant wins roughly 5-12% of chargebacks they choose to fight. Most merchants stop fighting after a few losses, because the time cost of preparing a response that has no real evidence behind it does not yield enough wins to justify.
On a terminal with proper evidence capture, the merchant wins 55-78% of chargebacks they fight. The evidence package speaks for itself. The issuer sees the signature, the timestamp, the location, the chip-read event log. The friendly-fraud claim falls apart on its face. The merchant wins the dispute, gets the funds back, and the issuing bank starts to recognize that particular cardholder as a chronic disputer.
What the merchant sees in their dashboard
A VendaPay merchant sees their chargeback queue as a live dashboard. Each chargeback row shows the original transaction ID, the cardholder card descriptor, the captured signature thumbnail, the terminal location stamp, the EMV event log, and the suggested response template. The merchant reviews the evidence, adds an optional note (often empty — the evidence is sufficient), and clicks submit. The full evidence package goes to the issuer in the format the network requires.
The whole process takes 90 seconds per chargeback, compared to 30-45 minutes of paper-chasing on a non-evidence-capture terminal. And the win rate is 5-10x higher.

What this means for evidence-capture decisions
If you are a Caribbean merchant and you do not know what kind of evidence your terminal captures at the moment of a transaction, find out. Ask your processor what their default chargeback evidence capture path looks like. If they cannot answer the question clearly, your terminal is not capturing evidence, and you are losing chargebacks you could be winning. Switching to a terminal with proper chargeback evidence capture pays back in weeks, not years.
