hello everyone.
i am not a techwizard so please dumb it down for me.
basically what i am trying to get done is this
a small calculator type device that can work offline. ( and occasionally get online using wifi chip)
it will have a nfc + wifi + fingerprint scanner + encryption chip.
it will contain some information on the chip, like points.
The device, when powered on, ( just like calculator) works like this.
All info is encrypted fully using the encryption chip onboard.
user gets some points from server, it shows on the screen the number of reward points. he can then give those points ( part or full) to someone else by using the keypad to type in the number,
use fingerprint scanner to digitally sign it ( or authenticate it) put his device next to the other persons device and points get transferred using nfc technology
use of wifi chip - then it gets connected to internet ( when possible)
point transfer is already complete,
it sends the info to the server, finalizing the points that way, even if the hardware device is lost, points are actually not, and he wont' be able to transfer points again.
now please tell me
1- the hardware that i will need ( links will be great, preferably from aliexpress.)
2 - software that i will need, if its coded already
3- any other info i will need to get started.
