[0456] Third, when placing 52 black balls into the box in order from left to right and top to bottom, the number of white balls placed into the box before the 52nd black ball is 33. Since 33 is not a multiple of 4, therefore:

[0462] Step 8: Divide the extracted characters 10011001100000011001100000000110001010000000011000000101000011000011000011001100001 into 21 groups of 4, as shown in the second column of Table 1.

[0468] Assume the traceability code (QR code) printed on the medicine packaging box corresponds to the traceability string 998198062806028618661;

[0469] The first step is to use a barcode scanner to scan the traceability code printed on the medicine packaging box, and the traceability string is obtained as 998198062806028618661.

[0470] The second step is to convert each character in the trace string 998198062806028618661 into binary: 100110011000000110011000000001100010100000000110000001010000000110000011000011000011001100001;

[0471] The third step is to generate a QR code using the name of the drug manufacturer (Chongqing Pujian Pharmaceutical Co., Ltd.), for example, as follows: Figure 2 As shown;

[0472] In the fourth step, when placing 52 black balls into the box in order from left to right and top to bottom, the number of white balls placed into the box before the 52nd black ball is 33. Since 33 is not a multiple of 4, therefore:

[0473]

[0474] Step 5: Since ψ is 1, change the first white box (or the second, third, fourth, ... or the 33rd white box) to an empty box (blue) in order from left to right, as shown below. Figure 3 As shown;

[0475] Step 6: Place each character of the binary trace string 10011001100000011001100000000110001010000000011000000101000011000011000011001100001 into a mapping table from left to right and from top to bottom, as follows; Figure 6 As shown;

[0476] Step 7: Extract the character 0000000000000000000000000000000 from the white area of ​​the mapping table in order from left to right and from top to bottom;

[0477] Since all the extracted characters are 0, the mapping table is correct. Proceed to the next step.

[0478] Step 8: Extract the character 1001100110011001100110011001100110011001100110011001100110011001 from the black area of ​​the mapping table in order from left to right and from top to bottom.

[0479] Step 9: Divide the extracted characters 1001100110011001100110011001100110011001100110011001 into 13 groups of 4; as shown in the second column of Table 2.

[0480] Table 2 Grouping - Character Comparison

[0481] Serial Number Grouping character 1 1001 9 2 1001 9 3 1001 9 4 1001 9 5 1001 9 6 1001 9 7 1001 9 8 1001 9 9 1001 9 10 1001 9 11 1001 9 12 1001 9 13 1001 9

[0482] Step 10: Convert the four-digit character into a single-digit character, as shown in the third column of Table 2; at this point, the traceability string 9999999999999 is obtained; therefore, by scanning the traceability code (QR code) printed on the medicine packaging box, the thirteen-digit medicine code 9999999999999 is obtained.

[0483] Scan 2:

[0484] Assume that the traceability string corresponding to the barcode printed on the drug packaging box is 9999999999999;

[0485] The first step is to use a barcode scanner to scan the barcode printed on the medicine packaging box to obtain the traceability string 2999999999999;

[0486] The second step is to convert each character in the trace string 999999999999 into binary as 1001100110011001100110011001100110011001100110011001100110011001100110011001;

[0487] The third step is to generate a QR code using the name of the drug manufacturer (Chongqing Pujian Pharmaceutical Co., Ltd.), for example, as follows: Figure 2 As shown;

[0488] In the fourth step, when placing 52 black balls into the box in order from left to right and top to bottom, the number of white balls placed into the box before the 52nd black ball is 33. Since 33 is not a multiple of 4, therefore:

[0489]

[0490] Fifth step, since ψ′ is 1, at this point, change the first white box (which could also be the second, third, fourth, ... or 33rd white box) into an empty box (blue) in order from left to right, as shown below. Figure 3 As shown;

[0491] Step 6: Place each character of the binary trace string 1001100110011001100110011001100110011001100110011001 into the black part of the left-to-right, top-to-bottom mapping table, as follows: Figure 4 As shown;

[0492] Step 7: Place 0s into the white boxes of the mapping table in a left-to-right, top-to-bottom order until the 52nd black box is placed; for example... Figure 5 As shown;

[0493] Step 8: Retrieve the character 1001100110000001100110000000011000101000000001100000010100000011000011000011000011001100001;

[0494] Step 9: Divide the extracted characters 10011001100000011001100000000110001010000000011000000101000011000011000011001100001 into 21 groups of 4, as shown in the second column of Table 1.

[0495] Step 10: Convert the four-character string into a single-character string, as shown in the third column of Table 1; at this point, the traceability string 998198062806028618661 is obtained; therefore, the traceability code 998198062806028618661 is obtained by scanning the barcode printed on the medicine packaging box.

[0496] Two-way verification 2:

[0497] Assume the traceability string 2 corresponding to the barcode printed on the medicine packaging box is 9999999999999; assume the traceability string 1 corresponding to the traceability code (QR code) printed on the medicine packaging box is 998198062806028618661;

[0498] The first step is to use a barcode scanner to scan the barcode printed on the medicine packaging box to obtain the traceability string 2999999999999;

[0499] Then, use a barcode scanner to scan the traceability code printed on the medicine packaging box to obtain the traceability string 998198062806028618661;

[0500] The second step is to convert each character in the trace string 999999999999 into binary as 1001100110011001100110011001100110011001100110011001100110011001100110011001;

[0501] The third step is to generate a QR code using the name of the drug manufacturer (Chongqing Pujian Pharmaceutical Co., Ltd.), for example, as follows: Figure 2 As shown;

[0502] In the fourth step, when placing 52 black balls into the box in order from left to right and top to bottom, the number of white balls placed into the box before the 52nd black ball is 33. Since 33 is not a multiple of 4, therefore:

[0503]

[0504] Fifth step, since ψ′ is 1, at this point, change the first white box (which could also be the second, third, fourth, ... or 33rd white box) into an empty box (blue) in order from left to right, as shown below. Figure 3 As shown;

[0505] Step 6: Place each character of the binary trace string 1001100110011001100110011001100110011001100110011001 into the black part of the left-to-right, top-to-bottom mapping table, as follows: Figure 4 As shown;

[0506] Step 7: Place 0s into the white boxes of the mapping table in a left-to-right, top-to-bottom order until the 52nd black box is placed; for example... Figure 5 As shown;

[0507] Step 8: Retrieve the character 1001100110000001100110000000011000101000000001100000010100000011000011000011000011001100001;

[0508] Step 9: Divide the extracted characters 10011001100000011001100000000110001010000000011000000101000011000011000011001100001 into 21 groups of 4, as shown in the second column of Table 1.

[0509] Step 10: Convert the four-character string into a single-character string, as shown in the third column of Table 1; at this point, the traceability string 998198062806028618661 is obtained; therefore, the traceability code 998198062806028618661 is obtained by scanning the barcode printed on the medicine packaging box.

[0510] Step 11: Since the traceability code 998198062806028618661 obtained by scanning the barcode printed on the medicine packaging box is consistent with the traceability string 998198062806028618661 obtained by scanning the traceability code printed on the medicine packaging box, two-way scanning verification is achieved.

[0511] Two-way verification 2:

[0512] Assume the traceability string 2 corresponding to the barcode printed on the medicine packaging box is 9999999999999; assume the traceability string 1 corresponding to the traceability code (QR code) printed on the medicine packaging box is 998198062806028618661;

[0513] The first step is to use a barcode scanner to scan the traceability code printed on the medicine packaging box, and the traceability string is obtained as 998198062806028618661.

[0514] Then, use a barcode scanner to scan the barcode printed on the medicine packaging box to obtain the traceability string 2999999999999;

[0515] The second step is to convert each character in the trace string 998198062806028618661 into binary: 100110011000000110011000000001100010100000000110000001010000000110000011000011000011001100001;

[0516] The third step is to generate a QR code using the name of the drug manufacturer (Chongqing Pujian Pharmaceutical Co., Ltd.), for example, as follows: Figure 2 As shown;

[0517] In the fourth step, when placing 52 black balls into the box in order from left to right and top to bottom, the number of white balls placed into the box before the 52nd black ball is 33. Since 33 is not a multiple of 4, therefore:

[0518]

[0519] Step 5: Since ψ is 1, change the first white box (or the second, third, fourth, ... or the 33rd white box) to an empty box (blue) in order from left to right, as shown below. Figure 3 As shown;

[0520] Step 6: Place each character of the binary trace string 10011001100000011001100000000110001010000000011000000101000011000011000011001100001 into a mapping table from left to right and from top to bottom, as follows; Figure 6 As shown;

[0521] Step 7: Extract the character 0000000000000000000000000000000 from the white area of ​​the mapping table in order from left to right and from top to bottom;

[0522] Since all the extracted characters are 0, the mapping table is correct. Proceed to the next step.

[0523] Step 8: Extract the character 1001100110011001100110011001100110011001100110011001100110011001 from the black area of ​​the mapping table in order from left to right and from top to bottom.

[0524] Step 9: Divide the extracted characters 100110011001100110011001100110011001100110011001 into 13 groups of 4; as shown in the second column of Table 2.

[0525] Step 10: Convert the four-digit character into a single-digit character, as shown in the third column of Table 2; at this point, the traceability string 9999999999999 is obtained; therefore, by scanning the traceability code (QR code) printed on the medicine packaging box, the thirteen-digit medicine code 9999999999999 is obtained.

[0526] Step 11: Since the drug code 9999999999999 obtained by scanning the traceability code printed on the drug packaging box is consistent with the traceability string 9999999999999 obtained by scanning the barcode printed on the drug packaging box, two-way scanning verification is achieved.
