TM1990A-F5 Stainless Steel Magnetic Dallas Ibutton Keyfob For Patrol Guard
The iButtons have an advantage over conventional smart cards in term of durability and longevity. The stainless steel casing gives iButton a far greater ability to survive in a range of temperatures -- all versions are functional from -40 C to +70 C -- and in a much harsher range of environments (such as exposure to salt water and long term exposure to physical impacts) than the plastic smart card. For e-commerce and personal ID usage, iButtons can be mounted on a range of personal accessories: watch, ring, key chain, or dog tag.
