Projects General Guidance

Hi Guys

Just about to start a project at college for my HNC. Just wanted to check if this is doable and how i can do it?

I want to read a barcode off an id card, which should give me a number and use that number to open a jpeg and load it to a touchscreen or display.

is this possible? and how can it be done?

Cheers

Doing the JPEG decode is going to rule out the eight bit Arduinos.

The eight bit Arduinos (Uno, Nano, Micro, Mega. . .) don't have the memory or the processing horsepower to decode a JPEG file in a reasonable time.
