It will still be in physical form, but for convenience, i prefer it to be contact less (no magstrip).
There are technology that cannot be replaced easily or become obsolete in next decade
e.g.
PC / laptop - if working on IT field (as developer, engineer, architect etc) PCs or laptop is still the weapon of choice. Tablets will not replace pc or laptop e.g. gaming (that needs multiple GPU and better played in mouse as its pointing device), developing apps, 3d modeling or creating expert systems will not suffice for the hardware architecture of tablet. Tablet is better for PMs/CEO (higher ups) who just manage teams / company
CC (credit card) - can be in a new form but there will be trillion$$ of investment to replace the existing magstrip cc (card and the "card reader") so i doubt it will be replaced after a decade from now. Smartphone can be good as replacement for CC but the problem is security (snatchers, hacking, etc). Even if you have fingerprint authentication, if one can reset the firmware, authentication is by passed. Realistically, to implement this smartphone and CC (as one), it can be in a some form of NFC (or similar) but transition of phones to this technology hasn't been a defacto standard in mobile phones thinking NFC has lingered for quite sometime.
keyboard/numeric pads mobile phones will be obsolete come 2020. touchscreen na lahat.![]()
Retz, entry level touchscreens are crap. I touch the icon and wait for 10 seconds for something to happen. Then I find out tapped the wrong icon and click "back" and wait another ten seconds. Later, I try typing out a text message at 10 seconds per letter......
an hour later, I was able to send "hello there". Ten seconds later, I got a reply... "who are you? wrong send"
