The iButton® is a 16-millimeter computer chip with its own unique ID number enclosed in a

detectors, water and most common chemicals.

The steel button is rugged enough to withstand harsh outdoor environments and durable enough for a person
to carry on their keychain.
You can drop it, step on it, scratch it or wear it swimming. The iButton is wear-tested for 10-year
durability and can be reassigned quickly and securely. It is by far the best solution for
both manufacturing and office environments.
In TimePilot's time and attendance systems and its CrossOver Lock
systems, the iButton is part of a keyfob that attaches to an employee's keychain. The keyfob and button
combination is about the size of a house key.
The standard keyfob color is black; 10 other colors are available. To order keyfobs with iButtons installed,
Who else is using the iButton?
Lots of companies are using the iButton for security, convenience or efficiency. Some examples:
- Employees at the U.S. Mint in Denver aren't allowed to carry money into the facility, so they use iButtons to operate the vending machines. Across Canada, many vending machines can be operated by iButtons or with cash.
- TimePilot offers a line of door locks that are operated by the same iButtons used by their timeclocks.
Besides providing security, the locks also record who operated the lock and when. You can also
add and delete iButton "keys" without the need for a locksmith
as well as give users the ability to open a lock with their iButton only at certain times and/or only between certain dates. For details, please visit www.CrossOverLock.com.
- A school in Celebration, Florida, issues iButtons to its students, who use them to open classroom doors and log onto computers. The school plans to expand the technology to its cafeteria, allowing students to pay for their meals with their iButton. This has the added benefit of privacy: Students are prevented from knowing which classmates are on a government-funded reduced-price or free meal program.
- Ryder truck rental mounts an iButton on the side of each of its trucks. The button records the truck number, its rental location, the customer's name and odometer reading at the start of the rental; when the truck is returned the information is downloaded into the company's database for billing.
- The mass transit system in Istanbul, Turkey, is one of the biggest users of the iButton. Some 1.4 million riders use iButtons to travel on the system's subways, buses, trains and ferries.
- Researchers studying human sleep patterns have found that their test subjects have a hard time sleeping while attached to a nest of wires, so they came up with a different method:
One version of the iButton tracks and records temperature, so the researchers tape Maxim's temperature logger iButtons to the subjects. The iButtons contain a clock, temperature detector and memory, and can record data every five minutes during the night. In the morning, scientists simply take the iButtons and download the data they have collected.
