New touring solutions rely on cloud-based Software as a Service (SaaS) combined with mobile or fixed on-site devices. These offer the advantages of lower installation and maintenance costs, forgoing the need for hardware, software upgrades, data backups and computer maintenance. On-site systems need all the usual software patches, backups and periodic hardware replacement. In operation, the role of the watchclock system, described above, has largely been replaced by some combination of GPS, RFID/NFC, or QR coded labels. Users prove that they have visited particular locations or performed tasks by scanning these tags or via GPS generated maps. These technologies result in lower costs, while increasing the flexibility of the systems to handle changes or new uses. This is important when routes change, or if a solution is needed on short notice. Tag-based touring systems typically utilize a mobile phone or tablet app to scan the tags and then upload that information along with a time stamp, phone's location information, and optionally other information the guard enters into the app on the phone. These systems provide instant access to tour information as it is uploaded by the application or device carried by the user, rather than requiring the officer to return to an upload station.
