Let’s take the policy issue outside the scope of the project review, in three years everyone has made up their minds and our opinion hasn’t changed.
We hosted the necessary couple of files on our server indefinitely and for free, setting up DNS and SSL certificate. This is what we do with all clients. Our server is spacious, it will not notice the extra few requests per day and the client has avoided the hosting issue for such a simple task.
At the same time, we always act in the client’s best interest and do not "bind". With paid hosting we put the files and do all the necessary customizations on that side.
By the way, we have experience of making business cards with even greater functionality and reliability. For this purpose we used pseudoplastic instead of cardboard (in fact, lamination), between the layers of which we placed an NFC-chip. All contact information was recorded in it, which can be read by any smartphone that is not ancient. As a result, for a business card to become useless, it is necessary to make it unreadable by the human eye, QR-scanner and by means of NFC, which is extremely unlikely.
By the way, if you register using our referral link, at the end of the free period you will get an additional month on the selected tariff if you pay for a year. We recommend this platform for simple projects, contact us — we will advise you.
