It used to be that everyone just carried around pictures in their wallets but now that photos have been digitized the playing field has changed completely. Enter in the digital photo key chain, a small photo display unit that will allow you to carry your pictures everywhere you go. In order to use a digital photo key chain you will need a computer and a digital camera. Depending on what kind of computer you have, you’ll want to get a key chain that supports either Windows systems or Mac and Windows Systems.
Generally, key chains come with its own proprietary software that you will need to install on your computer. This will allow you to copy photos to the key chain and to manage them going forward. There are some units that do not require this software and when you connect them to your computer they will act like flask disc key. These types of units are useful for people who are using Linux or other operating systems that are not as ordinary. acrylic charms
Most digital key chains on the market today come with 4MB or more of built in memory. The more memory the unit has, the more pictures you can store on it. Typically, 8MB will allow you to store enough pictures. The size of the screen can vary from 1.5 inches to 1.8 inches. Depending on the screen you may also not be able to see the pictures very clearly, so I would opt for a better screen even if it costs a few more dollars. Digital photo key chains are charged via a USB cable attached to a computer. The USB cable is also how pictures are copied to the key chain with the aforementioned software. Most of the key chain batteries will last for about 3 hours when fully charged.
To extend battery life only turns on the device when you wish to actively look at the pictures. The Coby 1.5″ digital key chain is a cheap model that I would recommend. It is compatible with both PCs and Macs. It has a whooping 16MB memory card and has a slide show mode. This device recharges through the USB and battery life is average. This is the best inexpensive digital key chains on the market in my opinion. If money is not of a concern then I would go with the Genius 1-Inch digital photo key chain.
