Metal credit cards require different disposal methods than plastic ones

Metal credit cards cannot go in a standard shredder or be snapped in half like plastic cards. The metal construction — usually stainless steel or aluminum layered with plastic — will damage most household shredders and cannot be broken by hand. Your options are limited to methods that physically separate the metal from any remaining data, render the card unusable, or send it to a facility equipped to handle metal.

The goal is to make the card unreadable and unusable before disposal. This means destroying the magnetic stripe, chip, and any embossed numbers. Because metal conducts electricity differently than plastic, some common destruction methods work differently or not at all.

Key Takeaways

  • Metal cards cannot be shredded in a home shredder and will damage the machine if you try.
  • A drill, grinder, or file can physically destroy the card's data-bearing surfaces, but requires safety precautions and creates metal dust.
  • Cutting the card into pieces with heavy-duty scissors or tin snips makes it unusable, though not completely data-proof.
  • Your card issuer may accept the card back for destruction, which is the safest option if available.
  • Soaking a metal card in water or freezing it does not destroy the data and is not an effective disposal method.

Contact your card issuer first

Before you destroy the card yourself, call the customer service number on the back of your card or log into your online account and ask whether the issuer will destroy it for you. Many issuers, particularly those offering premium metal cards, have return programs where you mail the card back and they handle destruction.

This is the lowest-risk option because the issuer has equipment designed for the job and can confirm destruction. You will need to request a replacement card or confirm that your account is closed before sending the original back. Ask the issuer whether you should cut the card first or send it intact.

Drill or grind the card's data surfaces

A power drill or angle grinder can destroy the magnetic stripe, chip, and embossed numbers in seconds. Put on safety glasses and work gloves, and do this outdoors or in a well-ventilated space because drilling metal creates fine dust. find the card in a vise or clamp so your hands stay clear of the spinning bit.

Drill or grind across the front of the card where the chip and magnetic stripe sit, and across the back where the signature panel and additional numbers appear. Make multiple passes to may support you have removed or deeply scarred these surfaces. A rotary tool with a grinding bit works for smaller areas if you do not have a full drill or grinder.

This method is fast and thorough, but requires you to own or borrow the equipment and take basic safety precautions. If you are not comfortable using power tools, the next method is safer.

Cut the card with heavy-duty scissors or tin snips

Heavy-duty kitchen scissors or tin snips can cut through a metal card, though it requires significant force. Cut the card into at least four pieces, making sure each cut goes through the chip and magnetic stripe. Cut both the front and back of the card to destroy all data-bearing surfaces.

This method is slower than drilling and requires physical effort, but it does not create dust and does not require power tools or a vise. The pieces will still be metal and should be disposed of as scrap metal or in your regular trash, depending on your local waste rules. Cutting alone does not make the card completely unreadable to specialized equipment, but it makes casual recovery of data impossible.

File or sand the card's surfaces

A metal file or coarse sandpaper can wear away the magnetic stripe, chip, and embossed numbers through repeated scraping. This is slower than drilling or cutting but requires no power tools and creates less dramatic metal dust. Work over a trash can or newspaper to contain the debris.

File or sand the front of the card where the chip sits, the back where the magnetic stripe runs, and any embossed numbers on the front. You will need to make many passes to fully destroy these surfaces. This method is most practical if you have time and want to avoid power tools or the effort of cutting.

What not to do with a metal card

Do not put a metal card in a home shredder designed for paper and plastic. The metal will jam the blades, bend them, or break them entirely. Shredders are not designed to handle metal and you risk damaging the machine and potentially injuring yourself if the card catches.

Do not soak the card in water, freeze it, or expose it to heat. These methods do not destroy the data and will not make the card unusable. The magnetic stripe and chip are designed to withstand temperature and moisture changes. Burning the card is also ineffective and creates toxic fumes from the plastic layers and any coatings.

Do not straightforward throw an intact metal card in the trash. Even if the card is expired or cancelled, the embossed numbers and chip can potentially be read by someone with the right equipment. Always destroy the data-bearing surfaces first.

Disposing of the destroyed card pieces

Once the card is destroyed, the metal pieces can usually go in your regular trash or recycling bin, depending on your local rules. Some areas accept scrap metal separately. If you drilled or filed the card, the metal dust should go in the trash, not down the drain.

If you are concerned about the pieces being reassembled or recovered, you can dispose of them in separate locations or mix them with other trash. This adds a layer of security, though it is not necessary if the data surfaces have been thoroughly destroyed.

Frequently Asked Questions

Can I put a metal credit card in a paper shredder?

No. Metal will damage or break the shredder blades. Paper shredders are designed only for paper and thin plastic. Use a drill, grinder, tin snips, or file instead.

Is it safe to drill a metal credit card at home?

Yes, if you take basic precautions. Wear safety glasses and work gloves, find the card in a vise, and work outdoors or in a ventilated space. The main risk is metal dust inhalation and the spinning bit catching your hand, both of which are preventable with setup and attention.

What if I lost my metal card and cannot contact the issuer?

Call the customer service number associated with your account (from a statement or your online banking portal) and report the card lost. The issuer will cancel it and can tell you whether they need the card back. If you later find it, you can then destroy it using any of the methods above.

Do I need to destroy the card before throwing it away?

Yes. Even an expired or cancelled card contains embossed numbers and a chip that could be read with specialized equipment. Destroying the data surfaces first makes recovery much harder and is a basic security step.

Can I recycle a metal credit card?

After you have destroyed the data surfaces, the metal pieces can often be recycled as scrap metal, though most curbside recycling programs do not accept small metal items. Check your local recycling rules or take the pieces to a scrap metal facility if recycling is important to you.
