Experiment with different techniques and conditions — The more you
experiment with different techniques, lighting conditions, scanning
distances and positions, the more proficient you will become.
Conclusion
Socket’s SD Scan Card 3E is a convenient and affordable bar code
scanning accessory for your mobile device, and with a little
experimentation and practice, the performance will approach that of the
larger and more expensive laser-based CompactFlash In-Hand Scan Card.
