MegaRetailer employee swipes MegaRetailer pre-paid Visa Debit card and puts 50 dollars on it without paying for it - filed as theft 50-500 by LE and misdemeanor division sent it over as a felony. My inclination is that it is 50-500 theft. 32.31(a)(4) says designated person or authorized bearer which is hanging me up - the prepaid debit card is universal by and in itself but the 50 on it is stolen from MegaRetailer. Thoughts? Similar Situations?

Was the card itself stolen? What was done with the card after it was "activated"? It seems to me you have described a bearer "debit card" within the meaning of 32.31 (a)(4). Sounds like the clerk is guilty of both theft and debit card abuse.
