Review: Toshiba NFC Card 16GB SDHC Memory Card

Toshiba NFC UHS-I 16GB Memory Card Front

Introduction

Toshiba brings Near Field Communication (NFC) to SD memory card with the NFC Card. This Class 10 SDHC memory card is the world's first SD card with built-in NFC. By tapping the card to a NFC enabled mobile phone, thumbnails and card information can be viewed without a physical connection to the card. The NFC SD card is powered by the radio frequency field from the mobile device.

Toshiba NFC Card 16GB SD Card Back

Toshiba NFC cards are currently available in 8, 16 and 32GB capacities. The 16GB card is tested for this review.

The NFC card has a white case with a bright green label. The top of the card is imprinted with a data matrix which appears to be a unique identifier for the card. The reverse of the card has the model number, batch identifier and indicates that this card was made in Japan. Toshiba NFC cards feature a five year warranty.

NFC communication

NFC provides radio communication between devices that are in close proximity to each other. It operates in the industrial, scientific and medical (ISM) radio band at 13.56 MHz with about 14 kHz bandwidth. Up to 424 kbit/s data rate is supported by NFC.

The Toshiba NFC card uses an NFC Forum Type 3 Tag compliant with ISO/IEC 18092 (NFCIP-1). This type of tag is re-writable and has variable memory capacity with a theoretical memory limit of 1 megabyte.

NFC Image Preview

The Toshiba Memory Card Preview is required to view thumbnails from the NFC card. This app is available for Android 4.0-5.0 devices. Memory Card Preview app version 1.0.2 (build 240) is used for this review.

Memory Card Preview App - Loading Card

To initiate communication, the NFC Card is placed against the back of the mobile device. Once the card is detected and communication beings, thumbnails begin to appear. Total time from initial connection to load 16 thumbnails was about 22 seconds. After the thumbnails are loaded the message "Data loading is completed" is displayed and the card can be moved away from the device.

Memory Card Preview App - Thumbnail View

The thumbnail view shows up to 16 images cropped into circular shapes. The app expands one thumbnail at a time in a slightly larger circle and scrolls the image. Images taken in portrait and landscape modes are shown in the proper orientation.

The 16 thumbnails are chosen according to specific criteria. The first image shown is always the most recent photo by the shooting date and time. Following this, up to 15 additional thumbnails are shown. First, images tagged "protected" by the camera are shown, starting with the most recent shot date. After this, at one image is shown for each day according to the shot date starting with the most recent. Finally, additional images are shown starting with the most recent.

It is not possible to change the order or view other thumbnails from the card. The thumbnails are ordered in specific positions on the screen, but these positions are scattered around the screen, making the order appear random. The help section under the app settings shows the order of the thumbnail positions.

Memory Card Preview App - Thumbnail Detail

Tapping a thumbnail will show the un-cropped thumbnail along with the shot date. Original file names are not displayed. Images are shown in 4:3 ratio with black borders added to pictures with different aspect ratios. Thumbnails are 160x120 pixel JPEG format images. Long-pressing a thumbnail allows it to be shared using other apps installed on the device. When shared, a thumbnail is given a numeric name using the original shot date and time, an underscore and a number (0-15), in the format: YYYYMMDDHHMMSS_N.JPG. Various thumbnails in this review ranged in size from 7 to 16KB.

Memory Card Preview App

Detailed card information can be seen by tapping the "i" icon on the card diagram in the center of the thumbnail view. This information includes the range of dates for shots on the card, a name (up to 80 characters) that can be edited to identify the card, a pie chart showing the card usage, the total size and number of images and other files on the card, as well as the total space used and available on the card.

Memory Card Preview App

Information for up to 20 cards can be stored in the app. The card index shows the last time each card was scanned. The card information and thumbnails saved in the app and can be accessed when the card is not present.

The app only shows thumbnails for images in sub-directories under the DCIM directory, the standard directory structure used by digital cameras. The app roughly follows the Design rule for Camera File system (DCF) by requiring sub-directories and images to be named with eight alphanumeric characters. Images in other locations on the card or not named according to these rules are not displayed by the app.

The app only reads JPEG format images. It did not read RAW files for any of the cameras tested (including cameras from Nikon, Canon, Olympus, Samsung, Sony and Pentax), nor did it load thumbnails for TIFF images.

Performance

Testing the NFC card using benchmark tests with USB 3.0 card readers, the card reached a 37.9 MB/s sequential read speed. The highest sequential write speed measured was 13.2 MB/s. While not incredibly fast, the card is fast enough to meet Class 10 specification (10MB/s continuous write speed).

Conclusion

The Toshiba NFC Card offers a unique way to preview images on the card. It only provides small thumbnails and can not download full images from the card. The NFC card in combination with the Memory Card Preview app is a quick way to get a general idea of what is on a card. The app is easy to use but the order it displays images could be improved. The limitation of 16 thumbnails, small thumbnail size and supporting JPEG images only will limit its usefulness for some users. As the first NFC-enabled SD card, Toshiba has shown it continues to bring innovative features to memory cards.
