What's the term for bank microdeposit, small test deposits that one bank sends to another to verify the second account's information and ownership?
Interesting, the literal meaning of  'micro-deposit' (微額存款) doesn't explain the actual function of it in English or Chinese. I would say translate 'micro-deposit' literally as 微額存款 is acceptable. Since people who know what 'micro-deposit' is, would also understand what 微額存款 mean. And people who don't know what 'micro-deposit' is, would need an explanation for 微額存款 just like they would need an explanation for 'micro-deposit'
If the translator worry about Chinese speakers who never heard of 'micro-deposit' will not understand what 微存款 mean, he might as well describe it in the name and write &quot;戶口認證用微額存款&quot; (Micro-deposit for account verification)
