SD ASSOCIATION EXPANDS iSDIO SPECIFICATION, ADDS HIGH-SPEEDCONTACTLESS DATA TRANSFER WITH TRANSFERJET
New iSDIO memory cards to feature fast contactless transfers between equipped devices
PHOTOKINA and SAN RAMON, Calif. – Sept. 16, 2014 – The SD Association (SDA), a global ecosystem ofcompanies setting industry-leading memory card standards, announced an enhanced iSDIO specification
offering a SD memory card with TransferJet contactless communications. Products using the specification
will be simple to use and feature secure connections for quick peer-to-peer data transfer.
The data recorded on an iSDIO TransferJet memory card can now be wirelessly communicated between
TransferJet equipped devices. Typical devices capable of supporting this contactless communication include
personal computers, smartphones and printers. The specification also facilitates the contactless datatransfer between other iSDIO TransferJet memory cards used in any type of device.
TransferJet technology provides high-speed contactless data transfer capability with the convenience ofsimply placing devices next to each other. Data is transferred at 560Mb per second with an effective
throughput of up to 375Mb per second. TransferJet data transfer speed is more than 1,000 times fasterthan the typical speed of NFC, allowing large data files like videos to transfer through TransferJet almost
instantaneously.
The iSDIO TransferJet specification offers consumers another method of contactless communication. The
advanced, intuitive ease of use enabled by TransferJet technology gives consumers high performance filetransfers without the complicated configuration procedures common with other wireless systems.
"The SD Association is giving consumers and businesses more convenient choices to move their large
movie, photo, music and data collections wirelessly between devices in record time,” said Brian Kumagai,
president of the SD Association. "We know that it’s difficult for just one technology to do everything, so wecontinue to expand our renowned data storage capabilities with wireless conveniences whenever possible.
We were able to complete the iSDIO specification update quickly thanks to our recently announced
collaboration with the TransferJet Consortium.”
The SD Association and TransferJet Consortium, the international group developing industrial standards ofclose proximity and contactless high-speed data transmission technology, began collaborating in March,
2014.
TransferJet is a close proximity, high-speed contactless data transmission technology. It’s unique near-field
coupling feature enables simple and easy operation while maintaining security, data connection and highperformance. SD memory card standards provide massive storage capacities capable of supporting
memory-hungry picture and high-definition video files, including 4K and even 8k video, in the world’s
leading removable memory form factor.
