(3) application software of handheld terminal directly acts on the hardware layer, and software configuration is poor, and hardware has any change, and software all needs to do corresponding modification.

(4) do not provide application programming interfaces, can't carry out secondary development; The change of any application software all needs to begin to revise from bottom software, and software does not possess reusability and transplantability.

(5) do not support GPRS (General Packet Radio Service, general packet radio service) or WiFi wireless communication mode connecting systems such as (Wireless Fidelity, Wireless Fidelitys), be difficult to the long-time mobile operating that reaches real.

(6) do not support encrypting and authenticating, be not with PSAM (secure access module) card, can not satisfy the requirement of the safety certification payment of all-purpose card consumer field.
