5 QR Code Physical Characteristics 280
281
The exact physical tag is not specified, except for the following characteristics. 282
5.1 Level of Error Correction 283
284
QR codes SHOULD use the Medium level of error correction. 285
286
Note: A version 4 QR code with level medium correction contains up to 287
90 Alphanumeric characters. 288
5.2 Readability 289
290
The QR code format SHALL be correctly readable with standard readers, even when parts of 291
the QR code are dirty or damaged. 292
5.3 Size 293
294
The format SHALL allow a QR code with only mandatory parameters to be printed and 295
scanned on as little as a 7x7mm surface and still comply with the interoperability and 296
robustness requirement. Rationale: Some devices have tight space constraints on where to 297
print the QR-code and thus need a very small QR-code size. 298
5.4 Producibility 299
300
The QR code format SHALL be feasible to be added to the devices in mass production in a 301
cost-efficient manner. 302
