In example, the timestamp is 6 digits, first 3 the N days indicated among 1 year, latter 3 M minutes indicated among one day；Institute
Stating payment number includes coupons and payment accounts, is indicated with 11 digits, supplying with 0 less than 11；The type of payment is with 1
Digit indicates that number is that 0 expression is paid with coupons, and number is that 1 expression is paid with payment accounts；By the timestamp, described
The data of payment number and the type of payment are combined (can be to this 3 kinds of data any combination) and form 18 original
String code；
Such as: the timestamp of a consumption card is 101010, payment number is 12345678910, type of payment 0, then
18 original string codes are 101010123456789100；
The wherein encryption algorithm of the timestamp specifically:
The value of M is 0≤M≤1440, if the numerical value of 0≤M < 720, N indicate that practical number of days, the numerical value of M indicate real
Border the number of minutes；If the practical number of days of 720≤M≤1440, N adds 400 to indicate, the practical the number of minutes of M, which subtracts 720, to be indicated；
For example, timestamp is encoded to 050100 if today is the 50th day, the 100th minute among 1 year；If being today
The 50th day, the 1200th minute among 1 year, then timestamp is encoded to 450480；
Step 2, using the phone number of the holder of the payment number as encryption string code, to the original string code progress
Encryption, obtain 18 new string codes, can verify whether be holder operation；
Specifically: first 6 of the phone number are added by turn with original first 6 for going here and there code, not more than 10
Carry obtains one 6 results；Then latter 6 of the phone number are added by turn with 6 results, more than 10 not into
Position, obtains another 6 results；By preceding 6 numerical value in newest 6 results and the original string code, (this refers at 6
Between stab and 101010) be replaced after, obtain 18 new string codes；
For example, the phone number of the holder of the payment number is 15859090114, by first 6 of phone number
(158590) (timestamp: 101010) being added by turn, and the not-carry more than 10 obtains with first 6 of the original string code of bar code
One 6 as a result, i.e. 101010+158590=259500；Then by rear 6 (090114) of the phone number and this 6 knots
Fruit (259500) is added by turn, the not-carry more than 10, obtain another 6 as a result, i.e. 090114+259500=249614, then
18 new string codes are 249614123456789100；
Described 18 new string codes are added by turn with 18 using digital ciphers by step 3, more than 10 not into
Position, is obtained string number to the end, can verify whether to be operated using legal payment terminal；
It is assumed that this 18 application digital ciphers are 591350100853520400,18 new string codes
(249614123456789100) it is added by turn, the not-carry more than 10 obtains string number to the end, it may be assumed that
249614123456789100+591350100853520400=730964223209209500；
Step 4 after being encrypted the last string number again according to Obfuscating Algorithms, obtains final bar shaped yardage

In the last string number, the 1st is obscured position for determination, is from left to right carried out according to the 1st value
Index, the numerical value of index are from left to right to be followed successively by 0 to 17, and the value of holding the 1st and the value for obscuring position are constant, other value
Plus the value for obscuring position, the not-carry more than 10 obtains final bar code data；
From 18 last string numbers 730964223209209500 it is found that the 1st value is 7, then from left to right
Start to index, the 1st to index corresponding 0, then the 8th (indexing corresponding 7) to obscure position, the value for obscuring position is 2,
Then other than the value of the 1st and the 8th are constant, other value adds 2, obtains final bar code data, it may be assumed that
730964223209209500+022222202222222222=752186405421421722；
