       FIELD OF THE INVENTION  
         [0003]    This invention pertains to electronic circuits and, more particularly, to programmable radio frequency identification testing devices.  
         BACKGROUND OF THE INVENTION  
         [0004]    From the invention of paper thousands of years ago to the present date, paper has been used as the preferred medium by individuals and societies for the recording, processing and storage of information. With the introduction of computers into society, many of the functions previously performed exclusively with paper are now being accomplished by writing information on paper and entering the written information into a computer. Typically, the information written on paper is entered into computers by optically scanning the paper. The foregoing method of entering information into computers is inconvenient, because the paper must be placed directly on the scanner, and no intervening objects may be placed between the paper and the scanner. Another method utilized by the prior art for writing information on paper and entering the written information into a computer involved placing a piece of paper over an expensive digitizing pad and using a special pen that produced digital data by indicating the coordinates of the digitizing pad. Thus, heretofore, there was no economic, convenient way for wirelessly entering information written on plain paper into a computer.  
           [0005]    Another method utilized by the prior art for entering information into a computer involved the use of radio frequency identification (RFID) tags. The RFID tags were programmed to contain digital information either during the manufacturing of the read only memory portion of the RFID integrated circuit, or in the field using electromagnetic radio frequency signals to store information in the nonvolatile memory portion of the RFID tag. One of the difficulties involved in the utilization of RFID tags was that if an end user wanted to enter information into the RFID tag, the end user had to use a specialized device that communicated with the RFID tag through a radio frequency. Another problem involved in the utilization of RFID tags that were programmed by the manufacturer was that the end user had to share the information that was going to be programmed into the RFID tag with the manufacturer of the tag.  
           [0006]    An additional method utilized by the prior art for the scoring of multiple-choice and/or true or false tests, i.e., Scholastic Aptitude Tests, involved depositing graphite information by a pencil on specific portions of the card that was electrically read, based upon the conductivity of the deposited graphite. The prior art also used card readers to electrically and optically read punched cards to enter information into systems. The prior art also optically read markings on a page.  
           [0007]    Bar codes have been used in a wide variety of applications as a source for information. Typically, bar codes are used at a point-of-sale terminal in merchandising for pricing and inventory control. Bar codes are also used in controlling personnel access systems, mailing systems, and in manufacturing for work-in-process and inventory control systems, etc. The bar codes themselves represent alphanumeric characters by series of adjacent stripes of various widths or lengths, i.e., the Universal Product Code, planet codes, etc.  
           [0008]    A bar code is a set of binary numbers. It consists of black bars and white spaces. A wide black bar space signifies a one, and a thin black bar or space signifies a zero. The binary numbers stand for decimal numbers or letters. There are several different kinds of bar codes. In each one, a number, letter or other character is formed by a certain number of bars and spaces.  
           [0009]    Bar code reading systems or scanners have been developed to read bar codes. The bar code may be read by having a light beam translated across the bar code and a portion of the light illuminating the bar code is reflected and collected by a scanner. The intensity of the reflected light is proportional to the reflectance of the area illuminated by the light beam. This light is converted into an electric current signal, and then the signal is decoded.  
         SUMMARY OF THE INVENTION  
         [0010]    This invention overcomes the disadvantages of the prior art by providing a method that allows one to mark information with a pencil or conductive ink on a material equipped with a RFID type circuit, and have the marked information represent answers to questions or responses to queries that are stored in the RFID circuit. The material may be any cellulose type product, i.e., paper, cardboard, chipboard, wood or plastic, fabric, animal hide, etc. The marked entered information may be corrected by erasing the written information with a pencil eraser and writing new information on the paper with a pencil.  
           [0011]    This invention accomplishes the foregoing by utilizing the RFID serial number generation portion of the RFID circuit that is used when the RFID circuit is being read. In the prior art, the bits used to encode one&#39;s and zero&#39;s into the generation portion of the RFID circuit were typically fixed. This invention utilizes the serial number generation portion of the RFID circuit by exposing on a piece of paper some or all of the bits left open or closed to represent a binary values, i.e., ones or zeros. A user may complete the RFID serial number storage portion of the RFID circuit by filling in the space between the connections with a pencil to alter the binary values. Alternatively, the serial number generation portion of the RFID circuit may be exposed on a piece of paper with all of the connections made, and a user may break a space between the connections with a sharp instrument or hole punch to alter the binary values. Alternatively, the serial number generation portion of the RFID circuit may have some of the bits all ready left open or closed to represent a unique number.  
           [0012]    An additional advantage of this invention is that a RFID type circuit may be combined with marked information that is stored in a RFID circuit, wherein the marked information also forms a bar code.  
           [0013]    A further advantage of this invention is that when a business mailer receives a business reply envelopes and/or prepaid or customer paid post cards from their customers, they do not have to open the envelope or scan the post card to determine what information the customer is sending.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0027]    Referring now to the drawings in detail, and more particularly to FIG. 1, the reference character  10  represents a prior art RFID circuit. Circuit  10  may be the model MCRF  200  manufactured by Microchip Technology, Inc. of 2355 West Chandler Blvd, Chandler, Ariz. 85224. RFID reader  11  is connected to coil  12 , and  12  is coupled to coil  13 . Coil  13  is connected to modulation circuit  14 . Modulation circuit  14  is connected to clock generator  15  and rectifier  16 . Modulation control  17  is coupled to modulation circuit  14 , clock generator  15  and counter  18 . Counter  18  is coupled to column decode  20 . Row decode  19  is coupled to memory array  21 , and array  21  is coupled to modulation control  17 . It would be obvious to one skilled in the art that a battery may be used to supply power to circuit  10 .  
         [0028]    Reader  11  has a transmitter mode and a receiver mode. During the transmit mode of reader  11 , reader  11  transmits a radio frequency signal for a burst of time via coil  12 . After the transmission of a signal by reader  11 , reader  11  turns into a receiver. Coil  12  is inductively linked with coil  13 , and coil  13  receives the radio frequency signal from coil  12  and converts the aforementioned signal into inductive energy, i.e., electricity. When coil  13  has sufficient energy, coil  13  will cause clock generator  15  to generate timing pulses which drive counter  18 . Counter  18  drives row decode  19  which causes memory array  21  to read the fixed bit data pattern stored in memory array  21  one bit at a time. As the data bits are being read by array  21 , the data bits are transmitted to modulation control circuit  17 . Control circuit  17  sends the data bits to reader  11  via modulation circuit  14  and coils  13  and  12 .  
         [0029]    [0029]FIG. 2A is a drawing of a circuit  24  that replaces memory array  21  of FIG. 1 showing how programming of the bits may be accomplished by making the bits externally available for programming RFID circuit  10 . A plurality of sensor circuits  25  is contained in circuit  24 . Sensor circuits  25  are labeled SC  1  SC  2  SC  3  . . . SC  n . Line  29  is connected to SC  1  and graphite contact  52  and line  30  is connected to SC  2  and graphite contact  53 . Line  31  is connected to SC  3  and graphite contact  54  and line  32  are connected to SC  n  and graphite contact  55 . There is a sensor circuit  25  for each graphite contact. The description of FIG. 4 will describe how information may be entered into circuit  24  via graphite contacts  52 - 55 . SC  1  has an input  33 , which enables the data output  34 . Input  33  is connected to one of the n lines  37 , and data output  34  is connected to data line  36  and pull up resistor  35 . Data line  36  is connected to modulation control  17  (FIG. 1).  
         [0030]    When counter  18  selects the value  1 , column decode  20  will enable line  33 , which will cause the same logic level that is on graphite contact  52  to be placed on data output  34 . When line  33  is not selected, the value on graphite contact  52  does not have any influence on the data output line  34 . Enable outputs  33  for SC  1  . . . SC  n  are bundled together in lines  37  so that only one line  37  is turned on at a time. Lines  37  are connected to column decode  20 . Column decode  20  is connected to counter  18 , and counter  18  is connected to row decode  19 . Counter  18  generates a sequence of numbers from 1 through n to enable a different line  37  in sequential order. Thus, data line  36  will receive the data outputs  34  from SC  1  . . . SC  n  at different times.  
         [0031]    [0031]FIG. 2B is a drawing of a circuit  300  that is an alternate representation of circuit  24 , that replaces memory array  21  of FIG. 1 showing how programming of the bits may be accomplished by making the bits externally available for programming RFID circuit  10 . Circuit  300  includes AND gates  301 ,  302 ,  303  and  304  and OR gate  305 .  
         [0032]    One of the inputs of AND gate  301  is connected to column decode  20  and the other input to AND gate  301  is connected to one of the ends of resistor  322 , one of the ends of diode  306  and one of the ends of diode  314 . The other end of resistor  322  is connected to ground. The other end of diode  306  is connected to one of the terminals of toggle switch  310 , and the other end of toggle switch  310  is connected to row decode  19 . The other end of diode  314  is connected to one of the terminals of toggle switch  318 , and the other end of toggle switch  318  is connected to row decode  19 .  
         [0033]    One of the inputs of AND gate  302  is connected to column decode  20 , and the other input to AND gate  302  is connected to one of the ends of resistor  323 , one of the ends of diode  307  and one of the ends of diode  315 . The other end of resistor  323  is connected to ground. The other end of diode  307  is connected to one of the terminals of toggle switch  311 , and the other end of toggle switch  311  is connected to row decode  19 .

The other end of resistor  324  is connected to ground. The other end of diode  308  is connected to one of the terminals of toggle switch  312 , and the other end of toggle switch  312  is connected to row decode  19 . The other end of diode  316  is connected to one of the terminals of toggle switch  320 , and the other end of toggle switch  320  is connected to row decode  19 .  
         [0035]    One of the inputs of AND gate  304  is connected to column decode  20 , and the other input to AND gate  304  is connected to one of the ends of resistor  325 , one of the ends of diode  309  and one of the ends of diode  317 . The other end of resistor  325  is connected to ground. The other end of diode  309  is connected to one of the terminals of toggle switch  313 , and the other end of toggle switch  312  is connected to row decode  19 . The other end of diode  317  is connected to one of the terminals of toggle switch  321 , and the other end of toggle switch  321  is connected to row decode  19 .  
         [0036]    Column decode  20  and row decode  19  function by taking the selected output at logic one, i.e., a high level and keeping all the other outputs at logic zero, i.e., a low level. The output of AND gates  301 - 304  are connected to the input of OR gate  305 , and the output of OR gate  305  is data that is connected to the input of modulation circuit  17 . If switches  310 ,  311 ,  312  and  313 , respectively, remain open, AND gates  301 - 304 , respectively, will have a “zero” output. If switches  310 ,  311 ,  312  and  313 , respectively, are closed, AND gates  301 - 304 , respectively, will have a “one” output. The output of AND gates  301 - 304 , respectively, will be read when switches  318 - 321 , respectively, are closed.  
         [0037]    [0037]FIG. 3 is a drawing showing sensor circuit  25  of FIG. 2A in greater detail. The negative input of comparator  41  is connected to line  29 , and the positive input of comparator  41  is connected to line  38 . Comparator  41  may be a LM339N comparator. One end of line  38  is connected to a 2-3 volt reference voltage, and the other end of line  38  is connected to one of the ends of resistor  39 . The other end of resistor  39  is connected to the positive input of comparator  41  and one of the ends of resistor  40 . The other end of resistor  40  is connected to the input of NAND gate  42 , the output of comparator  41  and one of the ends of resistor  43 . The other end of resistor  43  is connected to a source voltage to act as a pull up resistor. The other input to NAND gate  42  is enable output  33 . The output of gate  42  is data output  34 . Resistor  39  may be 47,000 ohms, and resistor  40  may be 470,000 ohms. Resistor  43  may be 1,000 ohms. Comparator  41  has a positive feedback to provide a small amount of hysteresis  
         [0038]    Sensor circuit  25  is a differential circuit that accommodates variations in the conductivity of the conductive material. The conductive material may be used as a voltage divider to produce V ref  on line  38  under the same conditions experienced by paper  in  on line  29 . Thereby, nullifying the effects of varying resistance in the conductive material. It will be obvious to one skilled in the art that sensor circuit  25  may replace switches  310 - 313  and  318 - 321  of FIG. 2B.  
         [0039]    [0039]FIG. 4 is a seller-furnished form to be completed by a buyer returning goods to a seller. RFID circuit  10  is attached to paper  50  by means of a conductive adhesive such as an anisotropic adhesive (not shown). The seller places a returned goods identification number  51  on the form to identify the buyer by writing the invoice number for the purchased goods on paper  50  in a manner that number  51  may be read by a RFID reader. Graphite contacts  52 ,  53 ,  54  and  55  and lines  56 ,  57 ,  58 ,  59  and  60  are printed on standard bond paper, standard photocopier paper, standard computer paper, etc., by a standard computer printer like the model Desk Jet 880C printer manufactured by Hewlett Packard using a Hewlett Packard 45 black ink cartridge.  
         [0040]    If the buyer decides to return a shirt to the seller, the buyer uses a graphite pencil, i.e., number 2, HB, etc., or a Paper Mate® black ball point pen to fill in rectangle  61 . If the buyer decides to return pants to the seller, the buyer fills in rectangle  62  with a graphite pencil, and if the buyer decides to return shoes to the seller, the buyer fills in rectangle  63  with a graphite pencil. If the buyer changes his/her mind regarding the goods to be returned or makes a mistake in filling in one of the rectangles, the buyer could erase the penciled marking in the rectangle with a pencil eraser so that a RFID reader would only read what the buyer indicated on the finished form. The buyer would insert the finished form into a package (not shown) containing the returned goods, and the seller would be able to read the completed form when he/she receives the package with a RFID read without opening the package.

Lines  451 - 455  represent possible answers to a question on an examination. If a student thought the answer to the question were choice “c”, the student would use a pencil to fill in the rectangle “c” on line  453 .  
         [0042]    Graphite contacts  458 ,  459  and  460  and lines  461 ,  462  and  463  are printed on paper  443  by a standard computer printer like the model Desk Jet 880C printer manufactured by Hewlett Packard using a Hewlett Packard 45 black ink cartridge or a Hewlett Packard laser printer.

         [0049]    [0049]FIG. 7 is a drawing showing how a modified RFID circuit of FIG. 6, stores information in the RFID circuit and how the RFID circuit forms a bar code. If someone decided to use a graphite pencil, i.e., number 2, HB, etc., or a Paper Mate®) black ballpoint pen to fill in rectangles A, C, H, L, O and P. Rectangles A, would represent a binary one of a bar code, and a closed circuit will exist between contact  467 , line  485 , line  503 , and contact  504 . Rectangle C would represent a binary one of a bar code, and a closed circuit will exist between contact  469 , line  487 , line  503 , and contact  504 . Rectangle H would represent a binary one of a bar code, and a closed circuit will exist between contact  474 , line  492 , line  503 , and contact  504 . Rectangle L would represent a binary one of a bar code, and a closed circuit will exist between contact  478 , line  496 , line  503 , and contact  504 . Rectangle O would represent a binary one of a bar code, and a closed circuit will exist between contact  481 , line  499 , line  503 , and contact  504 . Rectangle P would represent a binary one of a bar code, and a closed circuit will exist between contact  482 , line  500 , line  503 , and contact  504 .  
         [0050]    It would be obvious to one skilled in the art if rectangles B, D, E, F, G, I, J, K, M, N, Q and R and were filed in with a graphite pencil, rectangles B, D, E, F, G, I, J, K, M, N, Q and R would represent binary ones; and, if rectangles A, C, H, L, O and P were not filed in with a graphite pencil, rectangles A, C, H, L, O and P would represent binary zeros. The lines and contacts connecting rectangles B, D, E, F, G, I, J, K, M, N, Q and R would be closed circuits, and the contacts connecting rectangles A, C, H, L, O and P would be open circuits.  
         [0051]    [0051]FIG. 8 is a drawing showing how a modified RFID circuit attached to a piece of paper provides information to the RFID circuit and how holes punched in the RFID circuit form a code that may be read by an optical reader. RFID circuit  10  is attached to paper  231  by means of an adhesive (not shown). Graphite contacts  232 ,  233 ,  234  and  235 , and lines  236 ,  237 ,  238 ,  239  and  240  are printed on paper  231  by a standard computer printer like the model Desk Jet 880C printer manufactured by Hewlett Packard using a Hewlett Packard 45 black ink cartridge. If a human user wanted to select the information represented by line  236 , the user would make a hole  241  on line  236 , and if the user wanted to select the information represented on line  238 , the user would make a hole  242  on line  238 . Lines  239 ,  240  and  236 , hole  241  and contact  232  will form an open circuit. Lines  238 ,  240  and  239 , hole  242  and contact  234  will form an open circuit. Light may be passed through holes  241  and  242  to repeat the information represented by lines  236  and  238 .  
         [0052]    [0052]FIG. 9 is a drawing of a material  500  to be completed by a party that is keeping track of goods that may be date sensitive, i.e., food, film, medications, batteries, products that have certain shelf lives etc. Label  500  may be: attached to a container that the goods are contained in; affixed directly to the goods, or placed in a container that holds the goods. RFID circuit  10  is attached to material  500 , by means of a conductive adhesive such as an anisotropic adhesive (not shown). The manufacturer, shipper and/or custodian of the goods may place the name, identity, and/or any other information relating to the goods in space  501 . Graphite contacts  502 - 548  and lines  550 - 596  are printed on material  500  with a standard computer printer, like the model Desk Jet 880C printer manufactured by Hewlett Packard using a Hewlett Packard 45 black ink cartridge. The two vertical sides of rectangles  597 - 642  respectively are connected to lines  550 - 595 . If the goods mentioned in identity  501  should be used before Mar. 3, 2004, someone may fill in rectangles  599 ,  611  and  642  with a graphite pencil and/or a ballpoint pen or if someone wanted to indicate that they received the goods on Feb. 1, 2002, they may fill in rectangles  598 ,  609  and  640  with a graphite pencil and/or a ballpoint pen.  
         [0053]    [0053]FIG. 10 is a drawing of a train ticket  644  that indicates the stop that someone contracted with the train company to be transported to. RFID circuit  10  is attached to material  643 , by means of a conductive adhesive such as an anisotropic adhesive (not shown). An employee of the train company may indicate the stop that the customer paid to go to, i.e., Stop  6  by filling in rectangle  670  with a ballpoint pen or with a standard computer printer, like the model Desk Jet 880C printer manufactured by Hewlett Packard using a Hewlett Packard  45  black ink cartridge. Graphite contacts  645 - 664  and lines  655 - 664  are printed on material  643  with a standard computer printer, like the model Desk Jet 880C printer manufactured by Hewlett Packard using a Hewlett Packard 45 black ink cartridge. The two vertical sides of rectangles  665 - 673  respectively are connected to lines  655 - 663 .  
         [0054]    [0054]FIG. 11 is a drawing of the front of a business reply envelope and a modified RFID circuit that may be inserted into the envelope. Business Reply envelope  675  has the name and address  715  of the recipient of envelope written on the front panel of envelope  675 . RFID circuit  10  is attached to material  676 , by means of a conductive adhesive such as an anisotropic adhesive (not shown). A customer or potential customer of the recipient of envelope  675  may place their name, corporate identity, and/or any other information relating to questions asked on material  676  in space  716 . Graphite contacts  677 - 689  and lines  690 - 702  are printed on material  676  with a standard computer printer, like the model Desk Jet 880C printer manufactured by Hewlett Packard using a Hewlett Packard 45 black ink cartridge. The two vertical sides of rectangles  703 - 714  respectively are connected to lines  690 - 701 .  
         [0055]    If the person answering the questions asked on material  676  purchased goods for their home, they would fill in rectangle  703  with a graphite pencil or ballpoint pen. If they purchased the goods for their manufacturing business, they would fill in rectangles  704  and  705  with a graphite pencil and/or a ballpoint pen or if they purchased the goods for their service business, they would fill in rectangles  704  and  706  with a graphite pencil and/or a ballpoint pen. If the goods were purchased for the government rectangle  707  would be filled in with a graphite pencil or ballpoint pen. The person answering the questions would fill in the one of the rectangles  709 - 710  to indicate their position. Rectangle  711  would be filled in with a graphite pencil or ballpoint pen to indicate model  1  and rectangle  712  would be filled in to indicate model  2 . If a check for under $1,000 (not shown) is enclosed in envelope  675  rectangle  713 , would be filled in with a graphite pencil and/or a ballpoint pen. If a check for over $1,000 (not shown) is enclosed in envelope  675  rectangle  714 , would be filled in with a graphite pencil and/or a ballpoint pen.  
         [0056]    Thus, the addressee of envelope  675  may use a RFID reader (not shown) to determine the answers to the questions indicated on material  676  without opening envelope  675 . Hence, the addressee of envelope  675  may process the envelopes in an order that depends upon the answers to the questions posed on material  676 . For instance, any material  676  that indicates a check for over $1,000 is enclosed will be processed first. It would be obvious to one skilled in the art that different questions may be asked on material  676  and/or a business reply card may be used with material  676  on its back surface.  
         [0057]    [0057]FIG. 12 is a drawing of a parking summons to be completed by authorized governmental personnel. RFID circuit  10  is attached to material  801 , by means of a conductive adhesive such as an anisotropic adhesive (not shown). The authorized governmental personnel may place the name, identity of the automobile, and/or any other information relating to the parking infraction in space  800 . Graphite contacts  802 - 870  and lines  750 - 795  and  720 - 742  are printed on material  801  with a standard computer printer, like the model Desk Jet 880C printer manufactured by Hewlett Packard using a Hewlett Packard 45 black ink cartridge or a Hewlett Packard laser printer. The two vertical sides of rectangles  900 - 960  respectively are connected to lines  750 - 795  and  720 - 742 . If the parking summons was issued on March 4, at 11:00 PM, the authorized governmental personnel would fill in rectangles  902 ,  908  and  959  with a ballpoint pen.
