Want your next postcard to express more than three cornball sentences? Soon you’ll be able to add video of your trip with the stick-on Memory Spot, developed by HP Labs. The two-millimeter-square chip packs in half a megabyte of flash memory and can swap all its data in less than a second, so you can load it up or read files off it almost instantaneously.
To exchange songs, short videos or other files, you’ll simply tap the chip with your cellphone or iPod, which could easily be equipped to read the tags. A tiny built-in antenna will send or grab your files over high-frequency radio waves. These waves are what let the Memory Spot transmit info 1,000 times as fast as RFID, and, with a mere one-millimeter range, they also ensure privacy.
Commercial uses are a few years off but could include patient wristbands that store medical records, printouts that also hold digital versions, or postcards that will make your friends really wish they were there. hp.com
