Quick answer

Black out member ID and group number, any SSN-based identifier on your health insurance card; keep your name and the insurer name and plan visible. Add a "For [purpose] only" watermark and export a flattened PDF from your iPhone — nothing uploaded.

What a health insurance card reveals

A health insurance card shows your name, member ID, group number, and plan details. Clinics, hospitals, and pharmacies copy it to bill your plan.

A member ID lets a fraudster get care or prescriptions billed to you and corrupt your medical history.

What to redact

  • Member ID and group number They enable medical-identity theft and fraudulent claims against your plan.
  • Any SSN-based identifier Some plans still use SSN-derived IDs — never expose them.

What to keep visible

  • Your name
  • The insurer name and plan, if the provider must confirm coverage

Redact your health insurance card in 4 steps

  1. Pick the photo. Open Cachera and choose the photo of your health insurance 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 member ID and group number and any SSN-based identifier. On export the pixels are destroyed — nothing is recoverable underneath.
  3. Add a purpose watermark. Stamp who the copy is for, e.g. "For [purpose] only", so it can't be reused elsewhere.
  4. Export and share. Lay it out on A4, export a PDF, and share it. Everything stays on your iPhone — nothing is uploaded.

FAQ

What should I black out on a health insurance card?

Hide member ID and group number, any SSN-based identifier. Keep your name and the insurer name and plan visible so the copy is still useful.

Is it safe to send a copy of my health insurance card?

Only a redacted one. A member ID lets a fraudster get care or prescriptions billed to you and corrupt your medical history. Black out the sensitive fields, add a purpose watermark, and share a flattened copy so it can't be reused.

Can redacted areas be recovered from the file?

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