MSI Mod 1010 Calculator

How MSI Mod 1010 Calculator Works?

The MSI Mod 1010 Calculator works by computing an MSI Mod 10 digit, appending it, and computing a second Mod 10 digit over the extended data.

1. 1Compute the first check digit with MSI Mod 10 (Luhn).
2. 2Append the first check digit to the data.
3. 3Compute a second Mod 10 digit over data plus first check digit.
4. 4Append both digits.

MSI Mod 1010 Calculator Formula

The MSI Mod 1010 formula is c₁ = Mod10(data) and c₂ = Mod10(data + c₁).

c₁ = Luhn(data)
c₂ = Luhn(data ‖ c₁)   (MSI MOD 1010)
Encoded = data ‖ c₁ ‖ c₂

• ‖ means concatenation.

c₁ = 3
c₂ = Mod10(12345678903) = 1
Encoded = 123456789031

MSI Mod 1010 Calculator Conversion Table

The MSI Mod 1010 conversion table lists data with both successive check digits.

What is MSI Mod 1010 Calculator?

An MSI Mod 1010 Calculator is a tool that computes 2 successive Mod 10 check digits for an MSI Plessey barcode.

The second digit adds protection against misreads that the first digit misses, at the cost of 1 more barcode character.

What are the uses of MSI Mod 1010 Calculator?

There are 3 main uses of the MSI Mod 1010 Calculator, including high-security shelf labels, scanner testing, and label audits.

• High-security shelf labels: Retailers that need stronger misread protection use 2 check digits.
• Scanner testing: Technicians verify the Mod 1010 setting on scanners.
• Label audits: Auditors confirm both digits on printed labels.
