How to Destroy a Metal Credit Card Safely and Completely
Metal credit cards feel satisfying to hold — but that same durability makes them significantly harder to dispose of than a standard plastic card. If you've received a replacement, closed an account, or simply need to retire an old card, destroying it properly matters both for your security and, in some cases, because your issuer requires it.
Here's what you need to know about safely and thoroughly destroying a metal credit card.
Why Metal Cards Can't Be Destroyed the Same Way as Plastic
Standard plastic cards can be cut into several pieces with household scissors and tossed out. Metal cards — typically made from stainless steel, titanium, or a metal-plastic composite — resist scissors almost entirely. Forcing a cut can damage the blades or leave the card only partially destroyed, which defeats the purpose.
The goal of destruction is the same regardless of material: render the card's sensitive data unreadable and the card itself unusable. That means:
- The card number
- The CVV/security code
- The expiration date
- The chip (if present)
- The magnetic stripe
Leaving any of these intact is a security risk.
What Your Issuer May Require First 🏦
Before you attempt to destroy a metal card yourself, check your card agreement or call your issuer. Many premium metal card issuers — particularly those offering high-end rewards cards — require you to return the card to them rather than destroy it independently. This is standard practice for cards with significant material value.
When you close the account or request a replacement, the issuer may mail you a prepaid envelope for return. If you don't use it and simply discard the card, some issuers reserve the right to charge a card replacement fee or flag the account.
If your issuer does not require return and leaves disposal to you, the following methods apply.
Methods That Actually Work on Metal Cards
Request Issuer Destruction
The simplest and most secure option. Many issuers accept returned metal cards and destroy them using industrial equipment. You have a verified chain of custody, and the job is done without any risk to you.
Use Metal-Cutting Shears or Tin Snips
Heavy-duty aviation snips or tin snips — available at most hardware stores — can cut through stainless steel cards. The approach:
- Cut through the chip first to disable it.
- Cut through the magnetic stripe in multiple places.
- Cut the card number into at least four to six separate pieces.
- Dispose of the pieces in separate trash bags or separate bins over multiple days.
Do not use standard kitchen scissors. Even "strong" scissors can crack or bend under the stress of cutting metal and create a safety hazard.
Dremel or Rotary Tool
A rotary cutting tool with a metal-cutting disc can grind through the chip, stripe, and card number effectively. This creates metal filings, so work outdoors or in a well-ventilated space, wear eye protection, and use a clamp — never hold the card by hand while cutting.
File or Grind the Surface Data
If cutting isn't an option, a metal file or angle grinder can obliterate the raised or printed numbers, the CVV, and the magnetic stripe. This doesn't destroy the card entirely but renders the sensitive data unreadable. Combine with cutting if possible.
What Doesn't Work ⚠️
| Method | Works on Plastic? | Works on Metal? |
|---|---|---|
| Household scissors | ✅ Yes | ❌ No |
| Microwave | ✅ Sometimes | ❌ Dangerous — fire risk |
| Soaking in water | ❌ No | ❌ No |
| Tin snips / aviation shears | N/A | ✅ Yes |
| Returning to issuer | ✅ Yes | ✅ Yes (recommended) |
| Rotary cutting tool | ✅ Yes | ✅ Yes |
Never microwave a metal card. The metal will arc and can cause a fire or damage the appliance.
Focusing on the Right Parts of the Card
You don't need to reduce the card to dust. You need to destroy the elements that enable fraud:
- The EMV chip — contains encrypted account data; cutting through it disables it
- The magnetic stripe — running along the back; cut across it multiple times or file it down
- The 15–16 digit card number — cut it into multiple non-sequential pieces
- The CVV — the 3–4 digit security code; obliterate it physically or ensure it ends up in separate pieces
Once these are rendered unreadable, the card cannot be used for purchases — online, in-person, or over the phone.
Separating and Disposing of Pieces
Even after cutting, don't put all the pieces in the same trash bag at the same time. Identity theft often involves sorting through discarded materials. Spreading disposal across different bins or different days adds a practical layer of protection.
Some people keep a small container near the shredder specifically for card fragments, mixing them with other paper shred before disposal.
One Variable That Changes the Answer 🔑
Whether you cut the card yourself or return it depends almost entirely on which issuer issued it and which specific card you hold. Premium metal cards from major issuers often have explicit return policies built into the cardholder agreement. Budget metal cards or store-issued metal cards may have no such requirement.
The card in your hand — its issuer, its material composition, and the terms you agreed to — determines which path applies to you. Pulling up your cardholder agreement or making a quick call takes two minutes and tells you exactly where you stand before you reach for the tin snips.
