How to redact your bank card for renting a car

Why the rental company asks for your bank card

Rental companies verify your license to drive and a payment method. A debit or credit card shows the long card number, expiry date, cardholder name, and (on the back) the CVV security code.

The rental company needs a valid license and a card backing the rental confirmed — not your license number or full card kept. The catch: the card number, expiry, and CVV together are all that is needed for fraudulent online purchases. That's why you should hand over a redacted copy — see the full bank card redaction guide or what to redact for renting a car.

What to redact on your bank card

• The middle digits of the card number (keep first 6 / last 4 at most) The full card number lets anyone charge the card.
• CVV / security code (back of card) Never share it — it is the proof-of-possession for online charges.
• Expiry date With the number it completes a usable card.

What to keep visible (so it's still accepted)

• The cardholder name
• The last 4 digits, if the receiver needs to match the card on file

The watermark to add

Stamp a purpose watermark so the copy can't be reused beyond renting a car:

Redact your bank card in 4 steps

1. Pick the photo. Open Cachera and choose the photo of your bank card with the system picker — only that photo is read, never your whole library.
2. Black out the sensitive fields. Drag a black block over the the middle digits of the card number and cvv / security code. On export those pixels are destroyed — there's no hidden layer to recover underneath.
3. Add a purpose watermark. Stamp "For this car rental only" so the copy can't be reused beyond renting a car.
4. Export and send. Lay it out on A4, export a PDF, and share it with the rental company. Everything happened on your iPhone — nothing was uploaded.

Is this OK to do?

FAQ

Will the rental company still accept a redacted bank card?

Yes. Keep the cardholder name and the last 4 digits visible so they can confirm what they need, redact only the sensitive fields, and add a clear "For this car rental only" watermark. A watermarked, partially-redacted copy is normal, accepted practice.

What should I never show on a bank card?

Hide the middle digits of the card number, cVV / security code, expiry date. The card number, expiry, and CVV together are all that is needed for fraudulent online purchases.

Can the black bars be removed from the copy later?

No. Cachera flattens the redaction into the image on export — there is no hidden layer beneath the black blocks, so the covered text cannot be recovered from the PDF.

Should I send the original bank card instead?

Counter staff often photocopy everything. Provide a redacted copy and show originals only if required at pickup. A redacted copy with a purpose watermark is usually the safer choice.
