Have you thought about trying to cut a hole and reverse mount the NFC chip through the board? I bet it could reduce the thickness just a bit and make the card functional without the added lump.
Hi Jim! Good idea! I was considering mounting the tssop package breach mount style (upside down) but I decided against it because a majority of the cards I hand out will not have the nfc chip soldered in (chips add an extra ~$1.00 per card) and I didn't want an unsightly hole in the card. There is a good middle ground as the chip comes in a XQFN8 package which is only 0.5mm z-height. The tssop package is about 1mm z-height. It's pretty crazy how tiny ICs get these days!
Have you seen the visa credit card with a dot matrix and button inputs? Its called CodeSure and it's made by SmartDisplayer. I think it could at least make a calculator, if not a tiny dictionary, depending on how much storage the thing has.
I just checked it out. That's pretty wild! I didn't know that existed. It reminds me of the Coin Card. It would be neat to implement a calculator. The big thing is to reduce the cost and minimize / automate the assembly. Flex PCBs are usually kinda pricey though, so it may be cost prohibitive to make something as thin as a credit card. It may be better to shoot for a super thin pcb, capacitive PCB touch buttons and a super thin LCD. Maybe a in-plane LCD so the lcd does not stick out of the card. You would just need to have a routed out hole for the LCD and you should be able to keep the calculator nice and thin. Good luck!

"Let's see Paul Allen's Card"
Hahaha. Paul Allen doesn't need an introduction though :D
Pretty awesome, I’m gonna look at the more of your web stuff

*Ah, yes* I love this design!
Thank you for sharing the video & the designs
Hey, is it possible to have the file you used to make these. Great Christmas Gift for my son. Or , I can pay you if you upload for me. Thanks.

Enjoy!

your website link needs to be updated to add .html
Does it work with ios?
could it be possible to upgrade your business card with rfid and cr2025 lithium battery too?
😎 Very cool!
Hello, you know of someone who can do my design on PCB, I only have one image in PNG but I do not handle the program
could you send me 1 of your cards?........and YES on the network thing
greeting from INDIA, can I get your mail I'D or any other contact method?
