Yes. This is ONLY possible with a digital business card.
For a paper business card, once you have printed out, you can not make changes, amendments, corrections or updates, unless you reprint it again at extra cost and discard all the old business card printout! What a waste. Common changes to your business card are: change of tel number, change of office address, change of job title, change of your personal picture, etc. But with a digital business card, you can make changes, amendments, corrections or updates, anytime even if you have sent it out! Your customers are always ensured to have read the latest version when they view your digital business card online!
