Nearly all ScoutPalDB users have or plan to purchase Dell Axim or HP iPAQ
PDA's; these devices typically have two slots at the top into which you can
plug a scanner and memory card. The bigger slot is called a CF slot. (Compact
Flash.) The smaller slot is called an SD slot. (Secure Digital.)
You can put a scanner in one slot, and a data card in the other slot. You
can choose to use a CF scanner with an SD data card, or use an SD scanner
with a CF data card. Either set will work for scanning merchandise with ScoutPalDB,
but most users choose to use a CF scanner with an SD data card.
The options are illustrated here:
Why a CF slot scanner and an SD slot data card is the usual choice:
- SD data cards cost less than CF data cards, and are widely available.
- Most newer computers have an SD slot. If not, SD card reader attachments
are low cost and widely available.
- CF scanners are stouter than SD scanners.
- The CF slot inherently grips attachments like a scanner more securely
than the SD slot can.
What you need to know about data cards:
- The ScoutPalDB database needs a card sized 1GB or more.
2GB SD Cards are typically priced around $10.
- IMPORTANT: Most Dell Axim's, other older PDA's,
and many older computer built-in card reader slots are NOT compatible with
SD cards larger than 2GB!!! Read the numbered points
below to learn more:
- We have found that some retailers (e.g. Walmart) sell certain card
brands that are internally actually 4GB cards labeled as 2GB!
These cards are not compatible. Naturally, changing the label
does not change what's actually inside the card. (SanDisk is the original
developer and owner of SD Card patents; we have not heard of any mislabeled
SanDisk brand card.)
- We have been told that in some regions 2GB micro-SD cards are
easier to find than standard-SD cards. But still, the micro-SD card itself
must still be sized 2GB or less. A micro-SD to standard-SD adapter sleeve
us then used to make the the card fit into a PDA and a typical card reader;
new micro SDs will typically come with the necessary adapter.
(Refer to the illustration on the right side of this page to visualize the
micro-SD card solution.)
- To find out the actual physical capacity of any given card: put the
card in your computer then click Start, then Computer; or
open the My Computer icon on your desktop. (Windows 8 or 10?
You may wish to first download and install the free
it will restore a more familiar Start button as well as other functions
that allow full access and control of the card and PDA, without affecting
Windows 8/10 features.)
- Windows Mobile 6 devices and Windows Mobile devices with built-in
micro-SD card slots usually will not have a 2GB card limit.
- Most PDA's can read any size CF card.
- You're going to need a way to
put your card into your computer
so it can be updated. If your computer does not have a compatible card
slot for your card, you'll need to buy an appropriate
they are widely available and typically priced under $20.
Check your computer! It may already have an SD card slot; some have a CF slot.
