A few months ago – we did an experiment where we ordered blank NFC cards from Amazon, printed some labels & attached them and then programmed them with some specialized software. It was very cool and reasonably economical… sadly, the solution had a very short lifespan. The ink would smudge quickly, the process itself was cumbersome and the printers & software to print the actual cards can go into the ten’s of thousands of dollars. After our mostly failed experiment, we did some shopping around and found these little beauties! Smart business cards from Kard6.com
