How to share a receipt without handing over your card number

Everyday Digital Privacy

Splitting a dinner bill, claiming an expense, proving a refund — sharing a receipt is one of the most ordinary things we do, and one of the easiest ways to leak more than we mean to. A photo of a receipt often carries your card number, your name, and where you were, all at once.

What a receipt actually reveals

The last four (or more) digits of your card, and sometimes the full number on older printers.
Your name, printed for chip-and-PIN transactions.
The merchant, date, and time — together, a small map of where you were and when.
Loyalty and account numbers tying the purchase back to you.

Whoever you send it to only needs the amount and maybe the items. Everything else is yours to keep.

The everyday fix

Snap or screenshot the receipt as usual.
Open it in Redacted.
Black-box the card digits, your name, and any loyalty or account number.
Leave the total and line items visible.
Download and send the clean copy.

The bigger habit

Receipts are a good reminder that privacy isn’t only about passports and ID cards — it lives in the small, forgettable images we share every week. Building the reflex to cover a card number is the same reflex that protects a boarding pass, a prescription label, or a parcel with your address on it.

None of this needs an account or an upload. The receipt stays on your device; only the redacted version goes out.
