A web program called OneWalmart GTA Portal keeps track of all timestamps in one place. Using an RFID card or a portable device, employees can use the GTA Portal Walmart to sign in and out. This makes the system usable at home, at work, or somewhere else. In order to spot data trends that might necessitate additional research into possible fraud or misconduct, Walmart also offers a more comprehensive picture of employee hours and attendance through the GTA Portal.
