Does Metal Interfere with Magnetic Strips?

If metal blocks RFID, does it block the magnetic strip too? Surprisingly, no.

HiCo vs. LoCo

Modern bank cards use High Coercivity (HiCo) magnetic strips. These are much stronger than the old hotel room keys (LoCo).

The Stainless Steel Advantage

Stainless steel is "Austenitic," meaning it is largely non-magnetic in its structure. It does not act as a magnet itself, so it won't erase your strip. We supply professional-grade HiCo strips in our kits that are shielded to ensure your data is readable by any POS swipe machine, from gas stations to vintage registers.
