Hewlett-Packard researchers have developed a memory chip with wireless networking capabilities that is roughly the same size as a grain of rice, the company said Monday.
Prototypes of the Memory Spot chip developed by HP Labs contain 256 kilobits to 4 megabits of memory and can transfer data wirelessly at speeds up to 10Mbps. There are eight bits in a byte. This amount of storage allows the chips to hold a short video clip, digital pictures or "dozens of pages" of text, HP said, adding that the chips do not require a battery.
Memory Spot chips get their power using a technique called inductive coupling, which allows power to be transferred from one component to another through a shared electromagnetic field. In the case of Memory Spot, this power is supplied by the device that is used to read and write data on the chip.
Data stored on Memory Spot chips could be accessed using a variety of devices, such as specially equipped cell phones or PDAs, making them suitable for a range of applications, such as adhesive attachments applied to a paper document or printed photograph, HP said.

Not all bytes have 8 bits. A lot of older mainframes have 7 -- that's why octal was popular once, and why UTF-7 is still widely used. A few had 9, although that wasn't widespread. Some specialized computing devices have anywhere from 5 to 10. So pointing out that it's 8, in the context of a whole new specialized chip, isn't redundant.

Eight bits in a byte? When did this happen?
I think the size of a byte became exactly eight bits in the 60s, though it's possible that other-sized bytes existed in machines developed into the 70s. These days the term is pretty unambiguous, but telecommunications standard documents usually prefer the term 'octet', since there have been bytes of other sizes (and even platforms with *variable-sized* bytes). In particular, 6-bit bytes were very common early in computing history.

It's not that people think there's 10 bits in one byte, it's that they think there's 1000 bytes in one KB.
And you know what? They're right. It's the programmers who fucked up when they started using standard ISO suffixes and modified what they meant. One kilometer is not 1024 meters, it's 1000. The hard drive manufacturers are right, the programmers are wrong.

First of all, it's modifiers for SI units, not "ISO suffixes". Second, a byte isn't an SI unit so claiming it's "wrong" to map kilo to 1024 in the context of something that doesn't have anything to do with SI is pointless. Many words are overloaded. We c

Seeing as how Memory Spot readers must be "positioned closely" to access the data stored on the chip, wouldn't these make a better choice for passports? I think this would alleviate a lot of fears.

The chips in the new passports are ISO 14443 smart card chips, not standard RFIDs, and they do use the same sort of RF communications technology as these Memory Spot readers, and do have a similarly short range.

RFID vs. HP's new chip (Score:5, Interesting)
RFID features longer range and a small uniform, pre-encoded response. (e.g. ID Badge at work) HP's new chip features shorter range and a larger response, selectable from a large pool of responses, and probably the pool of responses is changeable even after deployment.
As another poster said, the short ranges at which this thing would work will alleviate a lot of people's privacy concerns. Still I gotta say that tagging people is still tagging people.

Not at all. Passive RFID chips can have computational capabilities. A good example is Speedpass, which uses a challenge-response crypto system. It's bad encryption that was easily duplicated by some grad students at Hopkins, but it is done.

Commercial Use (Score:5, Interesting)
Pointing your cell phone at a product for price comparisons and technical specs, or getting a small video on an item in a museum, or collecting e-mail addresses on College Night, or brochures at a convention, or any other sort of "Additional Info" normally not available at the point of contact, seems to me to be an extremely sustainable business model at a minimum of cost and input.
RFID might not be a commercial utopia, but it's a good start in a direction we could've been taking 10 years ago.

But it could be fun to build memory into ordinary objects. You would not need any electrical contacts. All you need is a universal reader that can presumably be cheaply added to PDA, notebooks, etc. On top of that it'd be easy to write software that reads and writes these to do interesting things:

So far, RFID resonds with a number, then you then crossreference with some sort of database to see what that ID represents. This apreach has obious advantages, but was also dictated by the limited amount of data transmition capabilities of current RFID chips, without sacrificing distance.
This device described by HP would have the data on the RFID ship itself. This has the advantage that the reading device does not need to be connected to a r
