Outstanding For Long 1D & PDF417 Barcode Imager Sensor and Decoder Board built together The RT209 is outstanding in terms of reading those very longer 1d barcode and also those big PDF417 code in ID documents (ID card, driver’s license, passport). Application example: 1. For Long 1D barcode: In some countries, their mail express companies use express bill that printed very long 1d bar code, what’s more, the 1d code would be not clear enough, for this kinds of situation, you would can not find too many (especially when you source from China) barcode scanners that can read those codes, then this RT209 is your good choice. 2. For ID documents PDF417 code: The RT209 is also optimized for reading big PDF417 code, so it can read those PDF417 bar codes from ID documents (not for all of countries’ ID). If you have one project of access control for which you need to get a barcode scanner to read the big PDF417 code from the ID card/ driver’s license, then you have very limited choices. One choice is to buy from Honeywell/ Motorola, but of course the price will be high. Another choice is to source from China, but you would take very long time still can’t find one unless you are lucky enough to find this RT209 ☺
