A Performance Test on Scanner
A Performance Test on Scanner(control variable method)
1 same barcode ,different scanner, change the scanning distance, the farther the better.
2 same distance,different scanner,change the bar code size & density, the more intensive and smaller the scanner can scan , the better .
3 same distance,different scanner, gradually the use of wider bar code. the wider scanner can scan,the better.
4 same distance,different scanner, the worse barcode the scanner can scan ,the better .
5 same distance,different scanner, the barcode on the curved cambered surface the scanner can scan, the better.
6 using different scanners, scan more code system. can be compatible with more barcode code,the better.
7 same distance,same barcode,different scanner,the faster decoding speed, the better
