TM1990A - F5 Magnetic Dallas Ibutton Key Fob / Keyfob For Patrol Guard System

The electric key contains a chip with a globally unique and unchangeable serial number, so each person can be assigned their own unique key. With this technology you can implement a simple, efficient and cost effective access system for your home or business.

The iButtons have an advae 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.

Among the major successes for the iButton have been its use in many countries as an e-purse for the mass transit system; for parking meters; and as Blue Mailbox attachments that improve postal efficiency.

Advaes of iButton Devices:

When developing an iButton solution for an application, you can consider many complementary technologies. Bar codes, RFID tags, magnetic stripe, proximity and smart cards are some of the possibilities. Unlike bar codes and magnetic stripe cards, most of the iButton devices can be read AND be written to. In addition, the communication rate and product breadth of iButton devices go well beyond the simple memory products typically available with RFID. As for durability, the thin plastic of smart cards is no match for the strength of the stainless-steel-clad iButton device.
