Description:
OBJECT OF THE INVENTION 
     The present invention relates to a multi-communication assisted portable terminal, of the type used in management tasks of a retail business. 
     The object of the invention is to provide a robust, ergonomic point-of-sale terminal, of great durability and adaptable to people with physical disabilities. 
     BACKGROUND OF THE INVENTION 
     In the practical application scope of the invention, there are a large number of known devices or point-of-sale terminals, through which a retail business allows making the payment process easier by allowing clients to pay using a credit card. 
     This type of devices presents some problems which focus fundamentally in the following aspects:
         These devices are fragile, so that accidentally dropping them may cause them to break.   They are not suitable for use by people with physical disabilities.   It is usual for the paper access case to accidentally disengage.   Given its structure, the width of the paper used is greatly limited.   They have a high volumetry and a considerable weight.   They have reduced autonomy.       

     DESCRIPTION OF THE INVENTION 
     The terminal that is recommended has been designed to solve the aforementioned problems in each and every of the aspects discussed. 
     Therefore, based on the conventional internal structure of this type of devices, in which there is a power supply that feeds a microprocessor, associated to a card reader and equipped with a communications module, either wired or wireless, to establish communication with the corresponding banking company, the invention provides, as one of the multiple novelties, the fact of incorporating a touch screen with high brightness VGA resolution, whereby the representation of images, icons, and the like is possible, facilitating the use of the terminal. 
     According to another of the characteristics of the invention, the device incorporates a keypad with a joystick, which facilitates navigation, incorporating contextual operation keys, and reliefs in Braille. 
     Another novel characteristic consists in the incorporation of a large format printer in the device that allows a paper width of 80 mm, with capacity to print EAN 128 of 28-digit codes, allowing use of both 80 mm and 58 mm rolls. 
     Besides, the terminal is provided to incorporate a high resolution image scanner through which it is possible to capture images, as well as to read one and two dimension codes, bet capture, etc. 
     In regards to the means of payment, the device is equipped with magnetic stripe card readers, chip cards or “smart card”, as well as RFID cards (NFC), compatible EMV and PCI. 
     In accordance with another feature of the invention, It is anticipated that the point-of-sale terminal incorporates a high-quality audio circuit, with built in microphone, a circuit that, through the corresponding software allows listening, through audio (voice) signals, to operations that are being carried out which is ideal for people with visual disabilities. 
     As for the wireless/wired media, it is envisaged that the device incorporates GSM/GPRS technology, GPS, WIFI, Bluetooth, and LAN/Ethernet. 
     Externally, it is anticipated that the device is integrated into an ergonomic case, of small dimensions, incorporating rubber inserts in the critical areas, which protect the device from impacts, incorporating on its lower face, shoulder strap reinforced attaching means. 
     Thus, an extremely versatile point-of-sale terminal is achieved, with a great variety of peripherals installed therein in a minimum space, which facilitates all the necessary services for the comfortable and efficient development of the daily activities of the logistics sale personnel, all these with a great durability achieved by means of a ruggedized finish, a robust design, and special ergonomics, thought for prolonged used both in the exterior and the interior.

     PREFERRED EMBODIMENT OF THE INVENTION 
     In view of the above-mentioned figures, and especially  FIG. 4 , it can be observed how the multi-communication assisted portable terminal that is recommended is made, as it is conventional, from a microprocessor ( 1 ), associated to a power supply ( 2 ), a processor that has a communication module ( 3 ), a keypad ( 4 ), a screen ( 5 ), a printer ( 6 ), and means for reading banking cards ( 7 ). 
     Therefore, according to the invention, it is provided that the screen ( 5 ) is a touch screen with high brightness VGA colour resolution through which the representation of images, icons and the like that facilitate the use of the terminal, is allowed. 
     In turn, the keypad ( 4 ) has a numerical keyboard with Braille reliefs, incorporating a joystick ( 8 ) for navigation, and contextual operation keys ( 9 ). 
     The printer ( 6 ) has a 80 mm paper roll, that allows for 58 and 80 mm width rolls with capacity to print EAN 128 of 28-digit codes, its cover ( 10 ) being assisted by means of a locking mechanism by pressing the release button ( 11 ), which prevents the accidental opening of said cover, as it happens in the conventional terminals. 
     In addition, it is anticipated that the device incorporates a high-resolution image scanner ( 12 ), of 1.3 MPx or higher, which enables the capture of images, as well as reading one and two dimension codes. 
     Regarding the means for reading banking cards ( 7 ), it is provided that a magnetic stripe card reader ( 13 ), a chip card or “smart card” reader ( 14 ), as well as a RFID reader ( 15 ), EMV and PCI compatible, are integrated therein. 
     The microprocessor ( 1 ) is associated to an audio circuit ( 16 ), with software of the “text to speech” type, i.e., through which the operations carried out with the device become voice messages that are emitted through one or more speakers ( 17 ), likewise having a microphone ( 18 ), as well as the corresponding headphones inlet. 
     In regard to the communication module ( 3 ), it is envisaged that the following communication and positioning sub-modules are located therein: 
     
         
         
           
             Quadband GSM/GPRS ( 21 ), with built-in antenna in the terminal 
             Connector for external antenna ( 22 ) 
             WIFI ( 23 ) 
             GPS ( 24 ) 
             Bluetooth ( 25 ) 
             Lan Ethernet ( 27 ) 
           
         
       
    
     Additionally, the device has two mini USB ports ( 32 ) on a lateral of its case. 
     In regard to the external appearance of the terminal, it has been provided that its case ( 26 ) incorporates rubber reinforcements in correspondence with its vertexes, incorporating a pair of end parts ( 29 ), which are secured by screwing them to the case, endowed with elongated slots ( 30 ) to which a tape ( 31 ) functioning as an attachment element for the device is fixed. 
     In its lower face it also incorporates a large space in which a pack of high performance batteries ( 28 ) is placed. 
     The device thus described presents a reduced volumetry, with a weight around 805 grams, that allows storing a paper roll up to 15 meters long, with a high performance battery (4 AH), and a last generation microcomputer processor, with a RAM memory ( 19 ) of 512 Mb and a storage memory ( 20 ) of 4 GB.
