常见问题(FAQ)
How many different versions of QR codes are there?
Model 2 QR codes come in 40 versions. Version 1 is 21 x 21 squares and Version 40 is 177 x 177; each version adds 4 squares per side and holds more data.
Should I download my QR code as SVG or PNG?
Use SVG for print, because it scales to any size without losing sharpness, which matters for posters and billboards. Use PNG for websites, emails, and slides. QR TIGER offers both downloads.
What kind of data can a QR code store?
A QR code stores data in four standard modes: numbers, letters and numbers, binary data, and kanji. Numbers take the least space, which is why a Model 2 code fits 7,089 digits but only 4,296 letters and numbers.
Can one QR code hold more than one link?
Yes. A Link Page QR code shows all your links on one mobile page, and a Smart URL QR code sends each scanner to a different link based on language, time, scan count, or location. Both are dynamic.
Which QR code types work without internet?
Text, Wi-Fi, SMS, and Event codes store their data inside the code, so the phone reads them offline (sending the SMS still needs a mobile signal). URL codes and all dynamic codes need internet to open.
