The Spectrum Pro is an SRED device and as such will only output financial card data when it has been injected with a data encryption key (DEK). It can be injected with a demo key or with a production key. A demo key is knowable and is almost always the standard ANSI test key of 0123456789ABCDEFFEDCBA9876543210. When developing/integrating for the Spectrum Pro you will want to use a unit injected with a demo key so that you can decrypt the data to see what is actually being encrypted and passed to the acquirer (or gateway or decrypting party). Once in a production environment, you will need a unit injected with the acquirer's key. Only the acquirer will be able to decrypt the data.  

Look for the sticker: 

When ID Tech injects a data encryption key into a device, a small sticker is applied. The sticker shows the key's part number (e.g. IDT-KEYINJ-D01 is the part number for ID Tech's demo key). Most injection facilities will do something similar.
