The same tasks as a desktop wallet are carried out by mobile wallets. Mobile wallets facilitate payments through "touch-to-pay" and Near Field Communication (NFC) scanning of a QR code in physical stores. Examples of mobile wallets are Bitcoin Wallets, Hive Android, and Mycelium Bitcoin Wallets. Bitcoin wallets tend to be compliant with either iOS or Android systems. There is substantial malware posing as Bitcoin wallets, so before deciding which one to use, research options are suggested.
