The postage-stamp-size secure digital card fits in the expansion slot of many Palm handhelds and has an estimated street price of $129 (£91), Palm said at the Cellular Telecommunications and Internet Association (CTIA) event in Orlando.
Bluetooth is specification for radio-based wireless links among devices. The specification is developed, published and promoted by the Bluetooth Special Interest Group, a trade association comprised of many vendors. Backers of the technology had expected it to reach critical mass by now, but support by hardware makers remains limited.
In an effort to push usage of Bluetooth, Palm announced a marketing alliance with London-based Sony Ericsson Mobile Communications. US mobile phone operators, Cingular Wireless LLC will be the first to bundle Palm Bluetooth products with Sony Ericsson's T68i mobile phone, according to Palm.
A Palm PDA with the card can exchange data with other Bluetooth-enabled devices within a 10m. For example a user could access the Internet with the phone still in his pocket, dial phone numbers from the PDA, or wirelessly print on a Bluetooth-enabled printer from the handheld device, Palm said.
