Choose a USB drive that connects to the devices you will actually use, and check the scanner’s requirements if you plan to save scans directly to it. USB-A suits a USB-A port, while USB-C or a dual-connector drive is useful when your workflow calls for those connections. Choose capacity after checking compatibility, keep a separate copy of the receipts, and plan how to protect files containing personal information.
If you will save or open receipt files on equipment with a USB-A port, a USB-A drive offers a direct connection. For scanning straight to a drive, check the exact scanner manual before buying: its accepted file systems, capacities and device types may be more restrictive than its port suggests.
If one device uses USB-C and another uses USB-A, check both ports before choosing a drive. A dual-connector model can avoid an adapter when both devices accept external USB storage; a USB-C-only model will not plug directly into a USB-A port.
If scans include personal details, consider what happens if the drive is misplaced and follow the school’s storage policy. The Information Commissioner’s Office explains that encrypting personal information on USB media can protect it against unauthorised access, but the chosen method must also let you open the files where needed.
Start with the ports and any direct-scan requirements, then decide how to handle personal information and how much space your scan settings call for.
| Concern | What to check | Who this matters to |
|---|---|---|
| Device and scanner compatibility | Check whether each device uses USB-A or USB-C. For direct scanning, check the exact scanner’s accepted file systems, capacities and restrictions on security-enabled drives. | If I scan at school but open the files at home, I need a connection and format both devices can use; around 42% of consumers put compatibility first. |
| Protection of personal information | Check the school’s policy and whether a suitable protection method will work on every device that must open the receipts. | When receipts contain personal details, I want to limit access if the drive is lost without locking myself out of the files; roughly 33% of consumers make protection their primary concern. |
| Capacity and everyday handling | Consider the number of scans, file type and resolution before choosing capacity; check the drive’s physical design if you will carry it regularly. | I want room for revised scans and a drive I can carry between school and home; about 25% of consumers place capacity and handling first. |
A USB-C-only drive will not plug directly into a USB-A port, and a USB-A-only drive will not plug directly into USB-C-only equipment.
Check the ports on the scanner, school computer and home device that will handle the files. Choose a dual-connector drive only if you will use both connections.
Scanner rules can extend beyond connector shape. One Canon scanner manual, for example, specifies FAT16 up to 2GB or FAT32 up to 32GB and warns against drives with built-in security functions; those limits apply to the equipment covered by that manual, not every scanner.
For your exact scanner model, check supported file systems, capacity limits and any restrictions on security-enabled devices before selecting a drive for direct scanning.
Interrupting a write can damage the stored file or drive. Brother instructs users not to remove a USB flash drive while its scanner is scanning.
Wait until saving or copying has finished, then follow the device’s normal removal procedure where one is available.
A portable drive can be lost. The Information Commissioner’s Office identifies encryption as a way to protect personal information stored on USB media against unauthorised access.
Follow the school’s policy, store only the details needed for the project, keep a separate approved copy and make sure you can access protected files on the required devices.
Kingston has USB-A DataTraveler Exodia and dual USB-A/USB-C DataTraveler Duo models relevant to different device connections.
Samsung’s BAR Plus is a USB-A line to consider if a metal body and keyring loop matter when carrying a drive.
Transcend’s JetFlash 790C is a USB-C option for moving files between devices that accept USB-C external storage.
These drives offer stated storage capacities for project files, with options listed for USB-A or dual USB-A/USB-C use. Match the connector and any direct-scan requirements to your equipment before choosing; security features described in a product name do not establish that a scanner or school workflow will accept them.

Consider this model if receipt files need to move between USB-A and USB-C devices. Its name lists a USB 3.2 Gen 1 interface and fingerprint access; check how that access works on every required device and whether the scanner accepts the drive before scanning directly to it.

Consider this model when you need to move receipt files between USB-A and USB-C ports. Its name lists a USB 3.2 interface and a 360° swivel design; for direct scanning, check the scanner’s accepted capacity and file system before use.

Consider this model for equipment with a USB-A port. Its name specifies USB 3.2 Gen 1; if you will save scans directly to a scanner, check its accepted capacity and format rather than relying on the connector alone. If you need protected storage for personal information, confirm the available method against school policy and the devices that must open the files.

Consider the stated 64GB capacity if it suits your receipt files and other project work. Check the connector on the drive and the scanner’s accepted capacity and file system before planning to scan directly to it; keep a separate copy of the files.
Choose capacity after checking your scan settings and any scanner limit, rather than assuming a particular drive size is necessary. Brother’s scanning guidance includes file type, resolution and file-size options, all of which can affect how much space the saved files use; allow room for revised scans too.
No: direct scan-to-USB compatibility depends on the exact scanner model. A Canon manual, for example, specifies FAT16 up to 2GB or FAT32 up to 32GB and warns against drives with built-in security functions. Check your scanner’s manual rather than applying those model-specific limits to every machine.
Remove it only after the scan has finished saving. Brother instructs users not to remove a USB drive while its machine is scanning; if your device provides a normal eject or safe-removal procedure, follow it before unplugging the drive.
Not every school receipt project calls for an encrypted drive; consider what personal information the files contain and follow the school’s policy. The Information Commissioner’s Office says encryption can protect personal information stored on USB media against unauthorised access, particularly if the media is lost. Check that the protection method still lets you open the files on the required devices.
A USB 3.2 label alone does not establish the time a scanner will take to save receipt files. Samsung’s published BAR Plus figures are maximum sequential read speeds under specified conditions, not guaranteed write or scan speeds; check the scanner’s capabilities and the type of speed being quoted before using it to compare drives.
