In the era of constant connection, nothing is more powerful than the off switch. Today, about 50 employees of technology company Three Square Market in River Falls, Wisconsin, will have that power taken away, at least in some senses.

They have volunteered to have radio frequency identification (RFID) chips implanted into their hands 鈥� in the skin between the forefinger and thumb. They will be able to use these to log in to computers, activate snack machines and perform other minor office activities. A special 鈥渃hip party鈥� is being staged to meld workers with miniature machines.

As a move towards a dystopian tomorrow, it鈥檚 barely a baby step, but it still raises some uncomfortable scenarios.

There鈥檚 no doubt about the value of being able to connect effortlessly with nearby systems using something that can鈥檛 easily be lost or forgotten. Personal devices like phones and laptops increasingly rely upon biometric scanners to read fingerprints and retinas as replacements for passwords.

Wearable tech such as and allow users to log in to their computers and unlock doors with a wave. A chip implant seems like a convenient melding of the two: the physicality of biometric authentication with the broad utility of a wearable device.

Part of you

But that same combination has a darker version: think of it instead as the permanence of a biometric with the open connectability of a wearable signal. Once implanted, the chip is as much a part of the user as a fingerprint, an iris or retinal pattern, but doesn鈥檛 require the same positive action (touching a scanner, looking into a camera without blinking) to activate.

Moving an RFID chip within range of a reader is enough. Fortunately, the RFID chips being used, supplied by in Helsingborg, Sweden, only have a 15-centimetre range using a standard reader, and hold less than a kilobyte of data. This limits the potential for mischief such as unwanted tracking.

We can鈥檛 count on such limitations to continue. Greater range and computing power are inevitable, especially if the early generations show promise in real-world use.

Regardless of their capability, there are obvious cybersecurity problems that could arise from the use of easily read chips implanted in hands. A simple handshake could be an act of industrial espionage.

Less obvious 鈥� but no less troubling 鈥� are resulting civil liberties concerns. Present-day would fall by the wayside if it were enough simply to bring the device near.

No saying no

There鈥檚 a deeper issue, however. Devices that respond to proximity rather than active intent suggest a world where the option not to see a message or wake up a laptop has gone. A screen that lights up when its user approaches is demanding attention.

It becomes effectively impossible to quiet the everyday environment if our very presence is enough to activate digital systems.

Phones and smartcards can be left behind; watches and rings can be removed. For all intents and purposes, they can be turned off. The same cannot be said for subcutaneous implants eager to respond and connect to nearby signals.

For the people at Three Square Market聽鈥� and others who follow聽鈥� the immediate value of such an implant may be alluring; over time, the lack of an off switch, the inability to say 鈥渘o鈥� to a connection, may prove a far more substantial drawback.
