web - How to preserve user state in the transition between devices? -


recently came across problem users distracted when working mobile phones example when user shopping online, forget continue task, , there no solution can preserve state , later he/she can continue task his/her desktop.i wonder solution storing user state. moreover, here i'm concerned web applications, when user wants resume unfinished work, can desktop computer while work started mobile device.

my approach set cookie land on site. depending on how data want save start immediately, after search or viable when add item cart present them option of guest login asking username, use real time ajax check availability of name or present them random 4 digit number smoothly popup alerting them can use restore session on device ask email address think users prefer anonymous name unless planning register.

if accept guest login save cookie, username/code, page & items database period of 24-72 hours.
